Oxygen reduction reaction(ORR)and carbon dioxide reduction reaction(CO2RR)are of particular interest for energy conversion and storage and have drawn a lot of recent attentions.It is obvious that efficient electrocatalysts are highly needed to selectively accelerate the ORR and CO2RR at a low overpotential.Metalloporphyrins and the derivatives represent an important type of non-precious metal electrocatalysts(NPMEs).
