Urea is present in the environment as a result of large amounts of wastewater from various origins. One of the most effective methods for disposing of urea involves electrochemical oxidation. This study investigated the use of sintered Ni-Pt electrodes as anodes in the electrocatalytic oxidation of urea. The activity of the Ni-Pt electrodes was compared with those of conventional Ti/Pt and Ni electrodes. Based on our results, the sintered Ni-Pt electrodes exhibited much higher activity in the oxidation of urea compared with the conventional anodes.
