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

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.
