In this study, we developed a nitrate-coordinated iron–nickel hydroxide [NC–FeNi(OH)2] catalyst for hydrazine oxidation-assisted seawater splitting. Replacement of O2 evolution by hydrazine oxidation in a two-electrode setup resulted in a cell voltage of 1.20 V at 100 mA cm−2. This represents a voltage reduction of 470 mV compared to conventional seawater splitting. Additionally, NC–FeNi(OH)2 demonstrated remarkable stability over a period of 60 hours.
