[more] © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Mesoporous materials with carbon framework structure can offer distinctive functionalities with tunable electronic or catalytic properties. Many synthetic routes including hard or soft templating approaches are developed for the fabrication of various ordered mesoporous carbon based materials which have demonstrated unique catalytic and energy storage properties. So far, most of these techniques deliver only mesoporous carbon with amorphous wall structures which limit their performance in many applications. Fullerenes exhibit unique structure and significant properties including superconductivity, electrochemical stability, and heat resistance. Herein, for the first time, the preparation of highly ordered mesoporous fullerene C70materials with tunable porous structure and controlled rod-shaped morphology through the thermal oligomerization of fullerene C70molecules inside the mesopore channels of SBA-15 silica as a hard template with the help of chlorinated aromatics, wherein the solubility of fullerenes is high, is reported. It is demonstrated that these metal-free mesoporous fullerene C70framework with a high surface area and bimodal pores with multifunctionality exhibit excellent performance in the oxygen reduction reaction for fuel cells and supercapacitors. This simple strategy can also be extended to other fullerene nanostructures with different carbon atoms which can exhibit interesting physicochemical properties and find applications in catalysis and energy storage.

[more] © 2018 The Royal Society of Chemistry. Highly ordered and three-dimensional (3-D) mesoporous carbon materials were prepared through a nano-hard templating approach using FDU-12 silica with tunable pore sizes as a template, which was synthesized via a microwave-assisted method. Powder XRD and microscopic techniques such as HR-TEM, HR-SEM, and N2adsorption-desorption techniques were employed to characterize the structure and textural properties of the prepared mesoporous carbon samples. The characterization results reveal that all the mesoporous carbon samples show a 3-D porous mesostructure with tunable pore diameters (5.7 to 9.4 nm) and a large specific surface area in the range from 451 to 1251 m2g-1. The supercapacitive behavior of the cubic structured mesoporous carbons was determined using cyclic voltammetry, electrochemical impedance and charge-discharge measurements. The cubic mesoporous carbon materials exhibit a superior capacitive performance with a high specific capacitance value of 315.3 F g-1at the current density of 1 A g-1, which is much higher than that of hexagonally-ordered mesoporous carbon with large pore diameters, activated carbon, and carbon nanotubes. The materials also show excellent cyclic stability and extremely low resistance. The superior specific capacitance of these materials is attributed to the combination of excellent surface properties such as large specific surface area, large pore volume and uniform pore diameter, spherical morphology, and a 3-D porous system with cage-type pores.

[more] © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim Highly ordered mesoporous C60with a well-ordered porous structure and a high crystallinity is prepared through the nanohard templating method using a saturated solution of C60in 1-chloronaphthalene (51 mg mL-1) as a C60precursor and SBA-15 as a hard template. The high solubility of C60in 1-chloronaphthalene helps not only to encapsulate a huge amount of the C60into the mesopores of the template but also supports the oligomerization of C60and the formation of crystalline walls made of C60. The obtained mesoporous C60exhibits a rod-shaped morphology, a high specific surface area (680 m2g-1), tuneable pores, and a highly crystalline wall structure. This exciting ordered mesoporous C60offers high supercapacitive performance and a high selectivity to H2O2production and methanol tolerance for ORR. This simple strategy could be adopted to make a series of mesoporous fullerenes with different structures and carbon atoms as a new class of energy materials.
