It is of great importance to design and develop complex heterostructured nanocatalysts with superior electrochemical performance to that of single structured ones. Here, we report the hydrothermal fabrication of a hierarchical heterostructured CuO@ZnCo layered double hydroxide nanowire array on a copper foil (CuO@ZnCo LDH/CF). As a self-supported electrocatalyst for water oxidation, CuO@ZnCo LDH/CF has superior catalytic activity with the requirement of a low overpotential of 270 mV to attain 10 mA cm-2 in 1.0 M KOH. In addition, it shows strong durability to maintain its activity for at least 24 h.

分层CuO @ ZnCo LDH异质结构纳米线阵列，用于增强水氧化电催化作用。
设计和开发具有比单结构的电化学性能优异的电化学性能的复杂的异结构的纳米催化剂，具有重要的意义。在这里，我们报告了在铜箔上（CuO @ ZnCo LDH / CF）的分层异质结构CuO @ ZnCo层状双氢氧化物纳米线阵列的水热制备。作为水氧化的自支撑电催化剂，CuO @ ZnCo LDH / CF具有优异的催化活性，要求在170 MV的低过电势下在1.0 M KOH中达到10 mA cm-2。此外，它显示出很强的耐久性，可以将其活性至少维持24小时。
