Electron-transfer enhancement of urchin-like CoP–Ce2(CO3)2O/NF as an ultra-stable bifunctional catalyst for efficient overall water splitting

An urchin-like CoP–Ce 2 (CO 3 ) 2 O/NF bifunctional catalyst was successfully constructed by a facile hydrothermal and gas-phase phosphating process, which exhibits extraordinary HER and OER performance ( η 10 = 85.2 and 205.5 mV) in alkaline solution.
