Abstract

A facile unipolar pulse electrodeposition combined with the thermal oxidation method was applied for fabrication of CuO/Co₃O₄ composites on carbon electrode for water electrolysis, and it was found that the sea anemone-like one with a 3D hierarchical structure formed at −0.8 V exhibited excellent performance for water electrolysis at a low overpotential with high stability.
