Abstract

This invention relates to a mesoporous carbon material in the form of filaments having a high surface area. A process is also provided to produce mesoporous carbon material of high surface area. The process comprises drying a carbon material, surface oxidizing the dried material, stabilizing the surface oxidized material, and activating the stabilized material to produce a highly activated, mesoporous material.
