A functional bimetal is incorporated into Ni2P, where Fe atoms improve the conductivity for improving electron transfer, and Co atoms accelerate the self‐reconstruction process to favorably generate a Co and Fe co‐incorporated NiOOH species on the electrode surface for inhibiting the adsorption of Cl− ions, thus ensuring excellent oxygen evolution reaction selectivity and stability for large‐current‐density seawater splitting. Abstract Designing efficient and durable electrocatalysts for seawater splitting to avoid undesired chlorine evolu...
