Fourteen-Membered Macrocyclic Cobalt Complex Structure as a Potential Basis for Durable and Active Non-platinum Group Metal Catalysts for Oxygen Reduction and Hydrogen Evolution Reactions

active site of the Co-14MR catalysts are the reasons for their high durability. These findings suggest that the Co-14MR structure is a promising design for non-platinum group metal catalysts for proton-exchange membrane fuel cells and water splitting.
