Borocarbonitride (BCN) based materials are finding increasing attention for a range of applications owing to their outstanding features. BCN is generally realized through the coupling of carbon and boron nitride (BN) with the latter being analogous to graphene and recognized due to its good electrical/mechanical properties and thermal/chemical stability. Although BCN is widely acknowledged for tunable bandgap, one of its fascinating yet less explored aspects is porosity. The porous features including high surface area and pore size are always favorable factors to enhance the efficiency of non-porous materials. This review is focused on parallel coverage and comparison of BCN and BN in terms of their synthesis methods, structure-property relationships, and application perspectives. This review aims to provide the readers with up-to-date information on the aspects that have not been covered previously. The review also covers the detailed explanation and analysis of various factors affecting the structure and property relationship that could lead to the development of more advanced BCN nanoporous structures. In terms of the application perspectives, emerging fields such as energy storage and conversion and photocatalysis and conventional fields such as adsorption are covered and the review concludes by providing illustrations on current challenges and future directions.

Porous carbon materials with tunable micro and mesoporous structure, graphitic wall structure, and enhanced layer spacing are considered attractive materials for several applications, including adsorption and energy storage and conversion. However, it is challenging to design porous carbon with all these properties in a single system. Here, we present a facile and rational synthesis route to fabricate graphitized porous biocarbon nanosheets from a low-cost precursor through a simple integration of simultaneous ¿activation and graphitization¿ process using iron acetate and potassium acetate at a high temperature. The prepared materials show tunable micro and mesoporosity with an enhanced layer spacing and high crystallinity. These sophisticated materials exhibit a smooth switch over the micro and mesopores for either low (5.9 mmol g-1/ 0 °C/ 1 bar) or high pressure (16.7 mmol g-1/ 0 °C/ 30 bar) CO2 capture. The careful manipulation of the porous texture and the graphitization degree also allows for enhanced performance as LIB anodes (646 mAh g-1), which show good cycling and surpass the specific capacity of conventional graphite anode (372 mAh g-1). These findings exemplify the importance of designing intriguing materials for addressing climate change by reducing greenhouse gases as well as providing low-cost alternative energy storage resources.

Transition-metal nitrides have attracted significant attention because of their unique electronic and surface properties and superior chemical and mechanical stability. Although various metal nitrides nanostructures have been realized, it remains challenging to introduce porosity and the high specific surface in these nanostructures, but they are required to expand the application possibility of these materials in energy storage and conversion. Here, we report the preparation of nanoporous titanium carbonitride using a high-nitrogen-containing mesoporous carbon nitride, C3N6 (MCN-4), as a reactive template and titanium tetrachloride as the titanium source. Nitrogen adsorption and microscopic results reveal that the prepared samples are highly nanoporous in nature, and the optimized sample exhibits a specific surface area of 700 m2/g and a high specific pore volume of 1.3 cm3/g. With the slight variation of the amount of MCN-4 in the synthesis mixture, the composition and the crystal structure of the nanoporous titanium carbonitride can be finely controlled. Near-edge X-ray absorption fine structure and Raman spectroscopic analyses of these samples confirm that the titanium atoms are strongly bonded with both carbon and nitrogen. The electrochemical hydrogen evolution reaction measurements of the optimized nanoporous titanium carbonitride loaded with 5 wt % of platinum in acidic medium reveal a high electrocatalytic performance with the overpotential of 27 mV at the current density of 10 mA cm-2, which is similar to that of commercially available Pt/C which contains 20 wt % of Pt. The combination of nanoporous structure together with the highly conducting carbon matrix in these metal carbonitride samples really helps to enhance the electrocatalytic activity. This research reveals a great opportunity for the design of porous metal nitride-based nanostructures with different composition and the potential for these materials to be used in energy storage and conversion technologies.

We report an integrated approach by combining in-situ activation, doping and natural nanotemplating to design low-cost and highly efficient N-doped nanoporous carbons for energy storage and carbon capture applications. N-doped nanoporous carbons are prepared by impregnating sucrose, 3-amino 1,2,4-triazole and the ZnCl2 into the nanochannels of the mixed kaolin-halloysite nanotube nanoclay, followed by carbonization and clay template removal. The prepared materials exhibit micro and mesoporosity, high specific surface areas (1360¿1695 m2 g-1), and nitrogen content (7.73¿12.34 wt%). The optimized material offers the specific capacitance of 299 F g-1 (0.3 A g-1) and 134 F g-1 (10 A g-1) with excellent cycling stability (91% capacity retention after 4000 cycles/5 A g-1). N-doping together with the interconnected micro and mesoporous structure, offers a more ion accessible surface and further provides enhanced charge transfer, hydrophilicity, and the interaction of the electrode-electrolyte ions. The optimized material adsorbs 24.4 mmol g-1 of CO2 at 30 bar pressure and 0 °C. The synthesized materials performed better as supercapacitor and CO2 adsorbent than halloysite clay, kaolin clay, activated carbon, nanoporous carbons, and mesoporous silica. The method presented here will provide a unique platform for synthesizing a series of advanced nanostructures for electrochemical and carbon capture applications.

Transition metal nitrides have gained a lot of attention as they have a significant potential for the electrocatalytic applications owing to their unique structure and electrical properties. However, the synthesis of mesoporous metal nitrides without compromising their electronic conductivity and the porous features is quite challenging. Herein, we demonstrate an integrated strategy of combining reactive templating approach and the doping for the synthesis of highly crystalline and mesoporous titanium carbonitride (MTiCN) materials through a simple heat treatment of the mixture of titanium tetrachloride and mesoporous C3N5 via reactive templating approach. The synthesized MTiCN materials possess rod shape morphology, high specific surface area, and mesoporous structure together with the highly graphic carbon matrix which are inherited from the mesoporous C3N5. The optimized MTiCN exhibits considerable electrocatalytic hydrogen evolution reaction (HER) activity with a low onset potential of 37.6 mV vs RHE and Tafel slope of 34 mV.dec-1 which lies very close to the commercial platinum/carbon. This work would offer a simple solution for the rational design of series of porous transition metal carbon nitrides with excellent electrocatalytic properties using carbon nitrides with tunable nitrogen and carbon contents for electrochemical conversion and storage applications.

We demonstrate a synthesis of copper nanoparticles decorated over nitrogen-doped mesoporous carbon with different N and Cu contents which exhibit conducting, redox, basic, adsorption, and excellent textural properties. These materials are prepared through a nanotemplating approach by simultaneously encapsulating sucrose, guanidine hydrochloride, and Cu(NO3)2 into the porous channels of mesoporous SBA-15 at a low carbonization temperature of 600 °C. The prepared materials exhibit an ordered mesoporous carbon framework with bimodal pores, decorated with nitrogen and Cu functionalities on the surface of the pores and in the wall structure. The presence of nitrogen functionalities in the porous carbon matrix not only helps to reduce the Cu ions but also stabilizes the nanoparticles and offers redox sites, which are beneficial for adsorption and electrochemical applications. The optimized sample exhibits the highest adsorption capacity of different gases such as CO2 ¿ 22.5 mmol/g at 273 K, H2 -13.5 mmol/g at 77 K at 30 bar and CH4 - 5 mmol/g at 298 K and 50 bar. We also demonstrate that the prepared material shows a high selectivity of adsorption towards CO2 in a mixture of CO2/H2 and CO2/CH4 and it also registers a high supercapacitance of 209 F g-1 at a current density of 1 A g-1 with excellent cyclic stability.

One of the key focuses of the agricultural industry for preventing the decline in crop yields due to pests is to develop effective, safe, green, and sustainable pesticide formulation. A key objective of industry is to deliver active ingredients (AIs) that have minimal off site migration and non-target activity. Nanoporous materials have received significant attention internationally for the efficient loading and controlled, targeted delivery of pesticides. This is largely made possible due to their textural features including high surface area, large pore-volume, and tunable pore size. Additionally, the easier manipulation of their surface chemistry and stability in different environments are added advantages. The unique features of these materials allow them to address the solubility of the active ingredients, their efficient loading onto the porous channels, and slow and controlled delivery over time. One of their major advantages is the wide range of materials that could be suitably designed via different approaches to either adsorb, encapsulate, or entrap the active ingredient. This review is a timely presentation of recent progress made in nanoporous materials and discusses critical aspects of pesticide formulation and delivery.

Reversible polymer electrolyte membrane (PEM) fuel cells have attracted significant research attention in the last decade due to the associated benefits. However, flow-field design of the bipolar end plates, among various other parameters, largely affects its performance. Thus, the present paper focuses on determining hydrogen storage capacity of a typical activated carbon (aC) electrode employed in a reversible modified PEM fuel cell with varied designs of flow-field. Three flow-field orientations - pin-type, parallel, and interdigitated - are used and their performance is evaluated. The fabrication method of the electrode, reversible modified PEM fuel cell, and different orientations of micro flow channels is disclosed. The characterization of the employed aC electrode is done using scanning electron microscopy (SEM), x-ray diffraction analysis (XRD), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FTIR). The fabricated cells are tested by linear voltage sweep and results are recorded. The result analysis revealed that the interdigitated flow-field design leads to better distribution of the reactants and encourages higher hydrogen adsorption in the carbon electrode compared to the other flow-field designs under consideration. The electrochemical hydrogen storage capacity of the carbon electrode with interdigitated flow-field design is found to be 1.47 weight percentage (wt. %), whereas for parallel and pin-type designs, it stands at 1.40 wt. % and 1.36 wt. %, respectively. The obtained energy storage density is comparable with the commercially available metal hydride based compressed hydrogen canisters. It is surely a step forward toward developing a reversible PEM fuel cell with enhanced performance capable of storing the charge, like a battery, with many potential applications.

In order to overcome the current energy and environment crisis caused by fossil fuels depletion and greenhouse gas emission, it is indispensable to introduce new, eco-friendly, high-performance materials into energy conversion and storage applications. 2D transition metal oxides (TMOs) are regarded as the promising candidates due to their excellent electrochemical properties. However, their innate poor electronic conductivity greatly restricts their applications in energy conversion and storage. This review discusses and summarizes the developed strategies to overcome the limitation through surface modification including defect engineering, heteroatom incorporation and interlayer doping, as well as hybridization with conductive materials. In addition, a detailed summary of their synthesis and applications in supercapacitors, lithium ion batteries and electrocatalysis is included. Finally, future prospective such as opportunities and challenges is discussed for the successful implementation of 2D TMOs in the field of energy applications.

Nanoporous biocarbons derived from biomass have attracted significant attention owing to their great potential for energy storage and conversion and water purification. However, the fabrication technology for these materials requires high cost and corrosive activating agents such as KOH or ZnCl2 which is a huge hurdle for their potential commercialization. In this study, a low-cost synthesis strategy is introduced for the preparation of O and N functionalized nanoporous biocarbons using non-corrosive and low-cost potassium citrate as an activating agent and casein as a biomass source via a single-step solid-state procedure. The presence of O functional groups in the activating agent and a large amount of N in the biomass precursor facilitated the successful incorporation of both O and N atoms into the final nanoporous biocarbons. A series of O and N functionalized nanoporous biocarbons with tunable porosity, specific surface area, and pore volume was prepared by varying the amount of the activating agent and casein. The optimized material CPC-3, which was synthesized using a 1¿:¿3 ratio of casein to potassium citrate, showed a high surface area (2212 m2 g-1), a large pore volume (1.11 cm3 g-1), and an appreciable amount of surface oxygen-containing functional groups. With the advantages of excellent surface parameters and the O and N functionalities on the porous surface, the functionalized nanoporous biocarbons achieved a high CO2 adsorption capacity of 25.4 mmol g-1 at 0 °C and 30 bar and showed an impressive specific capacitance of 177 F g-1 in a three-electrode and 95 A g-1 two-electrode system at 0.5 A g-1 using 3 M KOH as an electrolyte. Interestingly, the functionalized nanoporous biocarbon with a high amount of micropores displays a CO2 adsorption capacity of 5.3 mmol g-1 at 1 bar/0 °C, which is much higher than that of the reported activated porous carbon materials and ordered mesoporous carbons. It is surmised that the reported unique fabrication approach and the multifunctionality nature of these fascinating materials offer exciting opportunities for cost-effective CO2 adsorption systems and highly efficient energy storage devices.

We investigated the CO2 adsorption and electrochemical conversion behavior of triazole-based C3N5 nanorods as a single matrix for consecutive CO2 capture and conversion. The pore size, basicity, and binding energy were tailored to identify critical factors for consecutive CO2 capture and conversion over carbon nitrides. Temperature-programmed desorption (TPD) analysis of CO2 demonstrates that triazole-based C3N5 shows higher basicity and stronger CO2 binding energy than g-C3N4. Triazole-based C3N5 nanorods with 6.1 nm mesopore channels exhibit better CO2 adsorption than nanorods with 3.5 and 5.4 nm mesopore channels. C3N5 nanorods with wider mesopore channels are effective in increasing the current density as an electrocatalyst during the CO2 reduction reaction. Triazole-based C3N5 nanorods with tailored pore sizes exhibit CO2 adsorption abilities of 5.6¿9.1 mmol/g at 0 °C and 30 bar. Their Faraday efficiencies for reducing CO2 to CO are 14¿38% at a potential of -0.8 V vs. RHE.

Highly efficient, low-cost electrocatalysts having superior activity and stability are crucial for practical electrochemical water splitting, which involves hydrogen and oxygen evolution reactions (HER and OER). The sustainable production of hydrogen fuel from electrochemical water splitting requires the development of a highly efficient and stable electrocatalyst with low overpotential that drives electrochemical redox reactions. Electrochemical water splitting using highly active nickel-iron layered double hydroxide (NiFe LDH) catalyst having a very high turnover frequency and mass activity is considered as a potential contender in the area of electrocatalysis owing to the practical challenges including high efficiency and long durability at low overpotential, which shows great potential in future hydrogen economy. This review includes certain recommendations on enhancing the electrocatalytic performance of NiFe LDH-based electrocatalyst, particularly through morphology engineering, construction of hierarchical/core-shell nanostructures, and doping of heteroatoms through combined experimental assessment and theoretical investigations, which in turn improve the electrocatalytic performance. Finally, emphasis is made on the bifunctional activity of the NiFe LDH catalyst for overall water splitting. At the end, the conclusions and future outlook for the design of the NiFe LDH catalyst towards scale-up for their use as electrolyzer at the industrial level are also discussed.

Aqueous film-forming foam, used in firefighting, and biowastes, including biosolids, animal and poultry manures, and composts, provide a major source of poly- and perfluoroalkyl substances (PFAS) input to soil. Large amounts of biowastes are added to soil as a source of nutrients and carbon. They also are added as soil amendments to improve soil health and crop productivity. Plant uptake of PFAS through soil application of biowastes is a pathway for animal and human exposure to PFAS. The complexity of PFAS mixtures, and their chemical and thermal stability, make remediation of PFAS in both solid and aqueous matrices challenging. Remediation of PFAS in biowastes, as well as soils treated with these biowastes, can be achieved through preventing and decreasing the concentration of PFAS in biowaste sources (i.e., prevention through source control), mobilization of PFAS in contaminated soil and subsequent removal through leaching (i.e., soil washing) and plant uptake (i.e., phytoremediation), sorption of PFAS, thereby decreasing their mobility and bioavailability (i.e., immobilization), and complete removal through thermal and chemical oxidation (i.e., destruction). In this review, the distribution, bioavailability, and remediation of PFAS in soil receiving solid biowastes, which include biosolids, composts, and manure, are presented.

Slags are a co-product produced by the steel manufacturing industry and have mainly been utilised for aggregates in concreting and road construction. The increased utilisation of slag can increase economic growth and sustainability for future generations by creating a closed-loop system, circular economy within the metallurgical industries. Slags can be used as a soil amendment, and slag characteristics may reduce leachate potential of heavy metals, reduce greenhouse gas emissions, as well as contain essential nutrients required for agricultural use and environmental remediation. This review aims to examine various slag generation processes in steel plants, their physicochemical characteristics in relation to beneficial utilisation as a soil amendment, and environmental implications and risk assessment of their utilisation in agricultural soils. In relation to enhancing recycling of these resources, current and emerging techniques to separate iron and phosphorus slag compositions are also outlined in this review. Although there are no known immediate direct threats posed by slag on human health, the associated risks include potential heavy metal contamination, leachate contamination, and bioaccumulation of heavy metals in plants, thereby reaching the food chain. Further research in this area is required to assess the long-term effects of slag in agricultural soils on animal and human health.

In this investigation, a hybrid of metal sulfide and carbon nitride (CN) is synthesized by in-situ chemical conversion between metallic species and a single precursor of carbon, nitrogen and sulfur elements through a strong p-d conjugation approach. It is observed that the local chemical alteration in the vicinity of N atom in the CN template triggers the formation of a highly p-conjugated CN system and efficient p-d hybridization at heterointerface. This is accelerated by partial substitution of the Fe atom for Mn ions in the MnS phase which significantly enhances the battery performance, delivering 2031 mA h g-1 after 500 cycles with inverse capacity growth. Via systematic in-depth characterizations, it is found that the gradual increase of Li-ion diffusion coefficients and charge transfer kinetics for repeated cycling is ascribed to the highly dispersed and uniform particles that are confined within the CN template through a strong p-d hybridization.

In this report, we demonstrate the preparation of a series of carbon nanospheres (CNSs) with high surface area and tunable sizes from natural bioresource, Arecanut kernels, by using direct pyrolysis. This method offers a convenient approach to induce porosity in the synthesized carbons without the need for an activating agent. The textural parameters including the specific surface area, pore volume, and pore size can be controlled by the simple adjustment of the carbonization temperature from 700 to 1000°C. The CNSs prepared at 700°C showed a low specific surface area, whereas the higher carbonization temperatures (800¿1000°C) supported the rise in specific surface area of the products (433.6¿1001.4 m2/g). The carbon, hydrogen, and nitrogen (CHN) analysis revealed that the CNSs exhibited a high purity with the carbon percentage ranging between 96 and 99%. The synthesized materials were tested as adsorbents for CO2 gas, and it was found that the CNSs with the highest specific surface area of 1001.4 m2/g registered the CO2 adsorption capacity of 14.1 mmol/g at 0°C and 30 bar, which is a reasonably high value among reported porous carbons prepared without activation. This value of CO2 adsorption also stands above the activated carbon and multiwalled carbon nanotubes. The excellent CO2 adsorption capability of these adsorbents along with their low-cost synthesis offers a feasible pathway for designing such materials for other applications as well.
