Nitrogen‐doped porous carbon nanosheets (N‐CNS) are synthesized by hydrothermal carbon coating of g‐C 3 N 4 nanosheets followed by high‐temperature treatment in N 2 . g‐C 3 N 4 serves as a template, nitrogen source, and porogen in the synthesis. This approach yields N‐CNS with a high nitrogen content and comparable oxygen reduction reaction catalytic activities to commercial Pt/C catalysts in alkaline media.
