Abstract Since formaldehyde oxidation reaction (FOR) can release H 2 , it is attractive to construct a bipolar hydrogen production system consisting of FOR and evolution (HER). Although copper‐based catalysts have attracted much attention due their low cost high activity, the performance enhancement mechanism lacks in‐depth investigation. Here, an amorphous‐crystalline catalyst amorphous nickel hydroxide‐coated copper dendrites on foam (Cu@Ni(OH) /CF) prepared. The modification Ni(OH) resulted in hydrophilic aerophobic states Cu@Ni(OH) /CF surface, facilitating transport liquid‐phase species electrode surface accelerating . Open circuit potential (OCP) density functional theory (DFT) calculations indicate that this core–shell structure facilitates adsorption HCHO OH − In addition, catalytic pathway are investigated through situ FTIR DFT calculations, results showed lowered energy barrier for C─H bond breaking H─H formation. HER//FOR system, Pt/C//Cu@Ni(OH) provide current 0.5 A cm −2 at 0.36 V achieve efficient stable production. This work offers new ideas designing electrocatalysts assisted with oxidation.
