Defective-Activated-Carbon-Supported Mn–Co Nanoparticles as a Highly Efficient Electrocatalyst for Oxygen Reduction

Abstract

A highly active and durable cathodic oxygen reduction reaction (ORR) catalyst is synthesized by introducing a small amount of Mn–Co spinel into a kind of defective activated‐carbon (D‐AC) support. It is assumed that the synergetic coupling effects between the unique defects in the D‐AC and the loaded Mn–Co spinel facilitate the ORR and enhance its durability.
