Enhancing oxygen evolution reaction performance via Zn/Fe co-doping in a Co 3 O 4 nanostructure: mechanistic insights and surface reconstruction dynamics

A Zn/Fe co-doped Co 3 O 4 was constructed by combining an etching treatment with a heteroatom doping process using ZIFs as precursor, which is found to generate highly active FeOOH/CoOOH species on its surface during OER and follow the LOM pathway.
