摘要：

In order to accelerate the reaction rate of water splitting, it is of immense importance to develop low-cost, stable and efficient catalysts. In this study, the facile synthesis of a novel rose-like nanocomposite catalyst (Ni2P/Fe2P/Fe3O4) is reported. The synthesis process includes a solvothermal step and a phosphatization step to combine iron oxides and iron-nickel phosphides. Ni2P/Fe2P/Fe3O4 performs well in catalyzing oxygen evolution reaction, with a very low overpotential of 365 mV to reach 10 mA cm(-2) current density. The Tafel slope is as low as 59 mV dec(-1). Ni2P/Fe2P/Fe3O4 has a large double-layer capacitance that contributes to a high electrochemically active area. Moreover, this catalyst is very stable for long-term use. Therefore, the Ni2P/Fe2P/Fe3O4 catalyst has a high potential for use in oxygen evolution reactions.
