英文摘要	Due to their importance for practical applications in energy conversion, resolving the kinetic issues of water-dissociation in alkaline media for Pt-based electrocatalysts remains an ongoing challenge. Herein, the electronic properties of Pt could be modified with a nickel nitride (Ni3N) support through forming an interface of a low ratio of Pt nanoclusters (Pt NCs)viaa simple impregnation approach combined with nitridation. 1.5Pt@Ni3N-360 can offer excellent bifunctional performance for both the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER) which is competitive with commercial IrO(2)and Pt/C catalysts under alkaline media. It shows a low overpotential at 10 mA cm(-2)(285 and 71 mV) and a small Tafel slope (57 and 48 mV dec(-1)) for OER and HER, respectively. The excellent bifunctional electrochemical activity of 1.5Pt@Ni3N-360 is due to the interface and synergetic effect between Ni3N and dispersed Pt clusters, which changes the electron distribution of the material, so that the hydrogen adsorption energy tends to the optimal value (Delta G(H*)similar to 0). It is believed that the utilization of low-ratio Pt as an co-electrocatalyst with a variety of metal nitrides opens new horizons and opportunities to fabricate more efficient electrocatalysts for broad applications in energy-related devices.
