Abstract
| - In this study, ordered macroporous carbon with a three-dimensional (3D) interconnected pore structure anda graphitic pore wall was prepared by chemical vapor deposition (CVD) of benzene using inverse silica opalas the template. Field-emission scanning electron microscopy, transmission electron microscopy, X-raydiffraction, Raman spectrometry, nitrogen adsorption, and thermogravimetric analysis techniques were usedto characterize the carbon samples. The electrochemical properties of the carbon materials as a carbon-basedanode for lithium-ion batteries and as a Pt catalyst support for room-temperature methanol electrochemicaloxidation were examined. It was observed that the CVD method is a simple route to fabrication of desiredcarbon nanostructures, affording a carbon with graphitic pore walls and uniform pores. The graphitic natureof the carbon enhances the rate performance and cyclability in lithium-ion batteries. The specific capacitywas found to be further improved when SnO2 nanoparticles were supported on the carbon. The specific activityof Pt catalyst supported on the carbon materials for room-temperature methanol electrochemical oxidationwas observed to be higher than that of a commercial Pt catalyst (E-TEK).
