英文摘要	The urea oxidation reaction has attracted increasing attention. Here, porous rod-like Ni2P/Ni assemblies, which consist of numerous nanoparticle subunits with matching interfaces at the nanoscale have been synthesized via a simple phosphating approach. Density functional theory calculations and density of states indicate that porous rod-like Ni2P/Ni assemblies can significantly enhance the activity of chemical bonds and the conductivity compared with NiO/Ni toward the urea oxidation reaction. The optimal catalyst of Ni2P/Ni can deliver a low overpotential of 50 mV at 10 mA.cm(-2) and Tafel slope of 87.6 mV.dec(-1) in urea oxidation reaction. Moreover, the constructed electrolytic cell exhibits a current density of 10 mA.cm(-2) at a cell voltage of 1.47 V and an outstanding durability in the two-electrode system. This work has provided a new possibility to fabricate metal phosphides-metal assemblies with advanced performance.
