title: Highly nitrogen doped carbon nanosheets as an efficient electrocatalyst for the oxygen reduction reaction.
abstract: In this work, highly nitrogen doped carbon nanosheets (HNCNSs) have been successfully prepared by annealing EDTA calcium disodium salt. They exhibited a direct four-electron reaction pathway and high stability as an efficient metal-free catalyst for the oxygen reduction reaction.
