Abstract

Herein, we demonstrate a new approach for the fabrication of N,O,S-tridoped porous carbon nanosheets with the assistance of colloidal silica. The carbon nanosheets with an optimal content of doped O (∼11.6%) present excellent performance toward the oxygen reduction reaction (ORR), with an onset potential (1.02 V) and a half-wave potential (0.86 V) comparable to those (1.04 V, 0.84 V) of commercial Pt/C electrocatalysts.
