Transition metal phosphides (TMPs) are widely applied in electrocatalytic reactions, such as the hydrogen evolution reaction (HER), due to their excellent physicochemical properties. However, when utilized CO2 reduction severe limits activation of molecules. In this study, oxygen atoms were successfully migrated from TiO2 into Ni2P nanoparticles through a simple impregnation and low-temperature phosphidation process, constructing an O–Ni2P/TiO2 nanowire array electrode that modulates surface electronic structure, inhibits evolution, promotes activation. At potential −0.4 V (vs RHE), CH4 production rate reached 1.46 μmol·h–1·cm–2, with Faraday efficiency 11.8%, maintained long-term stability during 36-h process. situ infrared spectroscopy revealed CO* CH3* intermediates easily formed on material, which key directly related CH4.
