▎ 摘　　要

A simple approach has been developed for anchoring three-dimensional network structured Ni-P nanowires on reduced graphene oxide (GO) via a one-pot solvothermal method. Both the reduction of GO and deposition of Ni-P nanowires are achieved by introducing NaH2PO2 center dot H2O in the reaction medium. Without GO in the reaction system, Ni-P nanowires are ready to be assembled to urchin-like microspheres. The hybrid electrode of Ni-P nanowires/reduced GO composite exhibits enhanced electrocatalytic activity towards the oxidation of methanol in alkaline solution compared with the bare urchin-like Ni-P microspheres, which is attributed to the larger surface area and improved conductivity resulting from the introduction of graphene sheets.
