▎ 摘　　要

NOVELTY - The preparation method of nitrogen-doped reduced graphene oxide-modified graphite felt electrode involves hydrophilically processing graphite felt electrode, dispersing in mixed solution of nitrogen-containing compound and graphene oxide and then freeze-drying, placing in tube furnace under nitrogen gas atmosphere and then heat treating and pyrolyzing. USE - The method is useful for preparation of nitrogen-doped reduced graphene oxide-modified graphite felt electrode. ADVANTAGE - The method enables preparation of nitrogen-doped reduced graphene oxide-modified graphite felt electrode with excellent electrochemical reversibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for nitrogen-doped reduced graphene oxide-modified graphite felt electrode prepared by the method.
