Urea electrooxidation-boosted hydrogen production on nitrogen-doped porous carbon nanorod-supported nickel phosphide nanoparticles
文献摘要：
Urea electro-oxidation reaction(UEOR)-boosted water electrolysis can supplant the kinetics-restricted oxygen evolution reaction(OER)and provide an energy-saving method of hydrogen generation.However,low UEOR activity and the poisoning issue of the catalyst limit its practical application.Herein,a simple coordination reaction is used to synthesize the dimethylglyoxime-NiⅡ complex(DMG-NiⅡ),which efficiently serves as the initial precursor to synthesize nitrogen-doped carbon nanorod-supported nickel phosphide nanoparticle(Ni2P/N-Cnanorods)nanocomposites.The density functional the-ory calculations and electrochemical results reveal that nitrogen doping can weaken the adsorption of hydrogen and the generated CO2,resulting in an enhancement of hydrogen evolution reaction(HER)and UEOR activity.In addition,N-doping can also promote the generation of Ni3+,which can further pro-mote the UEOR and HER performance.Concretely,the overpotential for the HER on Ni2P/N-Cnanorods-2h nanocomposites is only 201 mV at 10 mA cm-2,and the onset potential of the UEOR on Ni2P/N-Cnanorods-2h nanocomposites is only 1.34 V.Additionally,the Ni2P/N-Cnanorods nanocomposites also show excellent long-term stability due to the introduction of nitrogen-doped carbon material.Consequently,the symmetric Ni2P/N-Cnanorods-2h‖Ni2P/N-Cnanorods-2h urea electrolyzer requires 1.41 V of electrolysis voltage for urea electrolysis,which can be applied in energy-saving H2 production and environment purification.
