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.
设计和开发具有比单一结构纳米催化剂更优异电化学性能的复杂异质结构纳米催化剂具有重要意义。在此，我们报道了在铜箔（CuO@ZnCo LDH/CF）上通过水热法制备分级异质结构的CuO@ZnCo层状双氢氧化物纳米线阵列。作为用于水氧化的自支撑电催化剂，CuO@ZnCo LDH/CF具有优异的催化活性，在1.0 M KOH中达到10 mA cm-2的电流密度时所需的过电位低至270 mV。此外，它还表现出很强的耐久性，能够保持其活性至少24小时。
