Facile Synthesis of Zn/N‐doped CuO and Their Application in Oxygen Evolution Reaction

Zn/N‐doped CuO have been prepared by a series of processes like stirring, soaking and calcination. Firstly, Zn‐ZIF precursors were synthesized by a simple stirring method, which is the source of Zn element. And then after a series of soaking and calcination, CuO hydrangeas doped with Zn/N were successfully synthesized. The calcination temperature was changed to control the samples’ morphology and their performances. The obtained samples showed...
