Preparation and electrochemical characteristics of mesoporous carbon spheres …

A B S T R A C T Mesoporous carbon spheres serving as electrode materials for supercapacitors were synthesized by a facile polymerization-induced colloid aggregation method using melamines as a carbon precursor and commercial colloidal silica as a silica source for hard template. After the carbonization of as-formed resins-template composites at 1000 8C and the removal of the silica templa…
