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

structure and promote the generation of active (oxy)hydroxide species, are identified as key factors in enhancing the electrocatalytic performance. This work offers a novel concept for enhancing the electrocatalytic activity of electrocatalysts through doping strategies and provides guidance for the rational design of ideal electrocatalysts.
