| description | 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−2 in neutral electrolyte at only 1.51 V.
Mott–Schottky type Janus Co/CoP nanoparticles are constructed by a proof‐of‐concept strategy, promoting the overall water splitting activity as typical Mott–Schottky electrocatalysts. The electron redistribution at the Co/CoP interface significantly and generally boosts the catalytic activity of Janus nanoparticles for both hydrogen evolution reaction and oxygen evolution reaction across a wide pH range. |
