Compared with the oxygen evolution reaction (OER), the urea oxidation reaction (UOR) is more likely to react in an alkaline electrolyte, and the thermodynamic voltage of urea electrolysis is 0.37 V, which is much smaller than the theoretical voltage of water-splitting (1.23 V). In this work, a Ni–Fe...
