Cu dopant triggering remarkable enhancement in activity and durability of Fe-N-C electrocatalysts toward oxygen reduction

Doping of a second metal has been becoming a valid strategy to further improve the catalytic performance of Fe-N-C catalysts toward oxygen reduction reaction (ORR). A highly efficient Cu-Fe-N-C electrocatalyst for oxygen reduction has been prepared by pyrolyzing the precursor of Cu(OH)2-Fe(OH)3@ZIF-...
