• A template approach for the synthesis of porous cobalt phosphide nanoarrays (Co₂P/CoP NAs) is reported, which exhibits superior electrocatalytic activity and stability toward charge storage and hydrogen evolution.

• Using Co₂P/CoP NAs as a charge mediator, the H₂ and O₂ evolution of alkaline water electrolysis is separated effectively in time, thereby achieving a membrane-free pathway for H₂ purification.

• Introduction of easily oxidized chemicals to replace water oxidation triggers a low energy consumption path toward H₂ purification.
