Abstract

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.
