In this study, we developed a nitrate-coordinated iron-nickel hydroxide [N C -FeNi(OH) 2 ] catalyst for hydrazine oxidation-assisted seawater splitting. Replacement of O 2 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, N C -FeNi(OH) 2 demonstrated remarkable stability over a period of 60 hours.
