Through the transformation from layered double hydroxides (LDHs) to metal organic frameworks (MOFs) by a hydrothermal method, we have prepared a promising electrocatalyst (Ni_xV_1−x-MOF) for the oxygen evolution reaction (OER). The optimized Ni_0.9V_0.1-MOF has the best OER performance and only requires an overpotential of 290 mV to drive a current density of 150 mA cm⁻² in alkaline solution.

层状双氢氧化物阵列原位转化为NixV1-x-MOF的纳米花，作为高效，稳定的氧释放反应电催化剂

通过使用水热法将层状双氢氧化物（LDHs）转变为金属有机骨架（MOFs），我们为氧释放反应（OER）制备了有希望的电催化剂（Ni _x V _{1- x} -MOF）。经过优化的Ni _0.9 V _0.1 -MOF具有最佳的OER性能，在碱性溶液中仅需290 mV的超电势即可驱动150 mA cm ^-2的电流密度。
