Electrochemical water splitting to produce hydrogen fuel is a promising renewable energy-conversion ***-scale electrolysis of freshwater may deplete water resources and cause water scarcity ***,seawater electrolysis is a potential solution to the future energy and water *** seawater electrolysis,it is critical to develop cost-effective electrocatalysts to split seawater without chloride ***,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 *** dopants and polyanion-rich passivated surface layers in NFZ-PBA-S could effectively repel chlorine ions and enhance corrosion resistance,enabling its excellent catalytic activity and stability for seawater oxidation.
