Description
Summary:[Display omitted] A stepwise method is used to synthesize MOP-CAN from Cu-based metal-organic polyhedron (Cu-IPA) for the first time, which exhibits a satisfying oxygen evolution performance. •A copper-organic polyhedron of Cu-IPA is regarded as the source of copper and carbon content.•A type of Cu3N/Cu embedded in N-doped carbon material denoted as MOP-CAN is obtained.•The MOP-CAN uses nitride as the active site and graphite carbon as the conductive substrate.•The as-obtained MOP-CAN exhibits a satisfying oxygen evolution activity. A stepwise method is used to synthesize partially nitrided electrocatalyst from Cu-based metal–organic polyhedron for the first time. The obtained MOP-CAN shows trace Cu3N as well as metallic Cu nanoparticles anchoring on the graphitic carbon layer, which exhibits a satisfying oxygen evolution performance competitive to the precious metal-based catalysts.
