The Urea oxidation reaction (UOR) process has a slow four-electron transfer step, and it is necessary to design a catalyst with improved reaction kinetics and excellent mass transfer ability. Utilizing 316 stainless steel mesh (SSM) with mesoporous structure, A hydrothermal method and high temperature vapor phosphating methods were used for constructing a NiP2-FeP4(x:y)/SSM compounds, NiP2-FeP4(7:1)/SSM obtain the best performance with a potential of only 1.47 V at a current density of 100 mA·cm-2. Speculated that the exposure of active sites is ensured on the basis of retaining the Layered Double Hydroxide (LDH), and the synergistic effect of metal-like compounds NiP2 and FeP4 enhances the electron transfer ability, thereby improving the slow kinetics of UOR. Therefore, the NiP2-FeP4(7:1)/SSM complex is expected to be an effective catalyst for the electrooxidation of urea.
