二维（2D）材料已广泛应用于电化学转化技术中，尤其是在金属-空气电池中的水氧化反应（WOR）和水分解中。在这里，我们展示了一种简便的配体辅助合成方法，可促进2D层状双氢氧化物（LDH）向2D金属-有机骨架（MOF）的转化。CoFe-LDH前驱物充当可调节的金属释放源，控制2D MOF的异质成核。与大多数钴基电催化剂相比，优化的CoFe 2D MOF在玻璃碳电极上表现出优异的WOR性能（10 mA cm ^-2时的过电位为274 mV，Tafel斜率为dec ^-1的46.7 mV）和长期稳定性，这归因于独特的2D特性以及Co和Fe离子之间的耦合效应。更重要的是，这项工作突出了将2D LDH转换为2D MOF的能力，并揭示了WOR中优异性能的内在因素。
