Abstract
The present disclosure provides a catalyst for urea oxidation reaction, a method of preparing the same, and a use thereof. The catalyst for urea oxidation reaction includes transition metal oxides forming on a metal substrate, and the transition metals includes Fe, Co, and Ni. The method for preparing the catalyst includes contacting the metal substrate with a homogeneous solution to obtain the catalyst for urea oxidation reaction, and the homogeneous solution includes transition metal nitrate precursors and a sulfur precursor. The method of the present application is a low-cost, high-efficiency, and simple process that can be mass produced.
