Metallic Co2P ultrathin nanowires distinguished from CoP as robust electrocatalysts for overall water-splitting

Abstract

A rapid microwave-assisted preparation of Co₂P nanowires (NWs) is reported here, comparing with the CoP NWs. The characterizations and theoretical calculations indicate that Co₂P exhibits metallic properties with improved conductivity. The electrocatalytic hydrogen and oxygen evolution activities are then measured and discussed in the paper, which show the advanced efficiency of Co₂P NWs for the overall water-splitting.
