Abstract
The electrons transfer from Cu<sub>2</sub>O to NiCo<sub>2</sub>O<sub>4</sub> with the formation of Cu–O bonds at the interface of the NiCo<sub>2</sub>O<sub>4</sub>/Cu<sub>x</sub>O, making parts of the relatively inert Cu(<sc>i</sc>) into the active Cu(<sc>ii</sc>) and introducing abundant new active sites.
