Microwave quasi-solid-constructed Ni2P–Ni12P5-supported Os with unique metal–support interaction for anion-exchange membrane seawater electrolysis

. The cost calculation for the produced hydrogen reveals a low price of USD $0.92 per gallon of gasoline equivalent (GGE), which demonstrates its economic advantages for industrialized application. Moreover, various stability measurements revealed that the electrolytic cell system exhibits excellent durability without significant current fluctuations. This corrosion-resistant electrocatalyst with enhanced price activity and mass activity for sustainable seawater electrolysis will pave the way in the design of efficient electrocatalysts with diverse strategies from a novel vision.
