报道了一种可控的真空扩散方法，用于将碳包覆的金属Co纳米颗粒逐渐磷化成Co/CoP Janus纳米颗粒。Janus Co/CoP纳米粒子作为典型的Mott-Schottky电催化剂，在各种电解质中表现出优异的析氢和析氧反应性能，在沿着pH变化范围内具有很好的稳定性。Mott-Schottky Co/CoP催化剂可以作为双功能电极材料在宽pH范围内进行整体水裂解，并且可以在中性电解质中仅在1.51 V下实现10 mA cm− 2的电流密度。
A controllable vacuum‐diffusion method for gradual phosphidation of carbon coated metallic Co nanoparticles into Co/CoP Janus nanoparticles is reported. Janus Co/CoP nanoparticles, as typical Mott–Schottky electrocatalysts, exhibit excellent hydrogen evolution reaction and oxygen evolution reaction performance in various electrolytes across wide pH range along with high durability. The Mott–Schottky Co/CoP catalyst can work as bifunctional electrode materials for overall water splitting in wide pH range and can achieve a current density of 10 mA cm−2in neutral electrolyte at only 1.51 V.
