A Nickel‐Based Integrated Electrode from an Autologous Growth Strategy for Highly Efficient Water Oxidation

An integrated electrode with autologous catalyst-support features is designed for highly efficient water oxidation. The high performance arises from consubstantial growth of Ni(OH)2 on metallic Ni substrate by a controlled surface oxidation protocol. The integrated feature between the catalyst and the support brings extremely efficient charge transfer toward unprecedented water oxidation activity and affords excellent system stability.
