The electrocatalytic urea oxidation reaction (UOR) has emerged as a promising alternative to the oxygen evolution reaction (OER) for wastewater recycling and energy recovery. However, the traditional UOR pathway on NiOOH surface is hindered by the rate-limiting desorption of *COO and the competition...
