Dual-strategy engineered nickel phosphide for achieving efficient hydrazine-assisted hydrogen production in seawater.

ABSTRACT: Electrocatalytic hydrogen production in seawater to alleviate freshwater shortage pressures is promising, but is hindered by the sluggish oxygen evolution reaction and detrimental chloride electrochemistry. Herein, a dual strategy approach of Fe-doping and CeO₂-decoration in nickel phosphide (Fe-Ni₂P/CeO₂) is rationally designed to achieve superior bifunctional catalytic performance for the hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR) in seawater. Notably, the two-electrode Fe-Ni₂P/CeO₂-based hybrid seawater electrolyzer realizes energy-efficient and chlorine-free hydrogen production with ultralow cell voltages of 0.051 and 0.597 V at 10 and 400 mA cm^-2, which are significantly lower than those n
