Structure and Electrochemical Capacitance of Nitrogen-enriched Mesoporous Carbon

Nitrogen-enriched mesoporous carbon which has been successfully prepared from quinoline-polymerized pitch using mesoporous silica as a template denoted ordered hexagonal assembly of fibrous carbon having ca. 6–7 nm in diameter and higher capacitance amounting to 200–300 F·g−1 in H2SO4 electrolyte than ordinary mesoporous carbons prepared using divinylbenzene as a carbon precursor (<180 F·g−1).
