Direct solvothermal phosphorization of nickel foam to fabricate integrated Ni2P-nanorods/Ni electrodes for efficient electrocatalytic hydrogen evolution.

We report an easy one-step approach for fabricating integrated Ni2P-nanorods/Ni (Ni2P-NRs/Ni) electrodes by direct phosphorization of a commercially available nickel foam current collector under solvothermal conditions. The resulting self-supported Ni2P-NRs/Ni composite electrode exhibits high electrochemical performance towards hydrogen evolution reaction in acidic medium.
