Boosting activity toward oxygen reduction reaction of a mesoporous FeCuNC catalyst via heteroatom doping-induced electronic state modulation

Abstract

Mesoporous Fe and Cu anchored in N-, S-, and P-doped carbon (FeCuxNC) catalysts, revealing the presence of ordered mesoporous grain-shaped particles and demonstrating that the electronic state of the active sites (Fe–Nx) is controlled by their environments, which can affect ORR kinetics.
