Large-scale electrolysis of freshwater may deplete water resources and cause water scarcity worldwide. Thus, seawater electrolysis is a potential solution to the future energy and water crisis. In sea-water electrolysis, it is critical to develop cost-effective electrocatalysts to split seawater without chloride corrosion. Herein, we present zinc-doped nickel iron (oxy)hydroxide nanocubes passivated by negatively charged polyanions (NFZ-PBA-S) that exhibits outstanding catalytic activity, stability, and selectivity for seawater oxidation. Zn dopants and polyanion-rich passivated surface layers in NFZ-PBA-S could effec-tively repel chlorine ions and enhance corrosion resistance, enabling its excellent catalytic activity and stability for seawater oxidation.(c) 2023 Science Press and Dalian Institute of Chemical Physics, Chinese Academy of Sciences.
