Abstract Engineering the intermetallic nanostructures as an effective bifunctional electrocatalyst for hydrogen and oxygen evolution reactions (HER OER) is of great interest in green production. However, a few non‐noble metals act electrocatalysts, exhibiting terrific HER OER processes reported to date. Herein nickel–antimonide (Ni─Sb) dendritic nanostructure via cost‐effective electro‐co‐deposition method designed their electrocatalytic property toward unrevealed. The Ni─Sb delivers...
