| 英文摘要 | It is of significant importance to develop effective non-noble-metal catalysts for hydrogen evolution electrocatalysis under basic conditions. In this study, we demonstrate the facile construction of a Ni2P-CeO2 interface based on the central point that low-temperature phosphidation of the NiO-CeO2 precursor only converts NiO into Ni2P selectively. The resulting Ni2P-CeO2 nanosheet array on Ti mesh behaves as a durable catalyst for alkaline hydrogen evolution reaction (HER) electrocatalysis, and it can reach 20 mA cm(-2) at an overpotential of 84 mV in 1.0 M KOH, outperforming all reported Ni phosphide HER catalysts. Density functional theory calculations reveal that the Ni2P-CeO2 interface can promote water dissociation and optimize hydrogen adsorption free energy. |
