Abstract

An advanced electrode composed of porous CoP nanorod bundle arrays (NBAs) on Ti plate was fabricated by using Co3O4 NBAs as precursors and developed as a robust self-supported hydrogen-evolving cathode for electrochemical water splitting. Such electrode exhibited remarkable activity for hydrogen evolution reaction in a wide pH range, affording a low onset overpotential, small Tafel slope, and long-term stability.
