Abstract
Abstract The realization of seawater electrolysis requires the development of electrode materials that can meet the requirements of high activity, high selectivity, and corrosion resistance. Herein, this work successfully prepares a molybdate (MoO 4 2− )‐modulated nickel‐iron oxide electrode for seawater electrolysis via a quick and easy thermal shock method, with high activity and extraordinary durability in oxygen evolution reaction (OER) for seawater electrolysis. The experimental analyses and theoretical calculations reveal that the in situ generated MoO 4 2− on the surface of electrode can modulate and stabilize the catalytic active phase γ ‐(Ni, Fe)OOH, improving the OER activity, as well as play a…
