Nonporous MOF-derived dopant-free mesoporous carbon as an efficient metal-free electrocatalyst for the oxygen reduction reaction

In this work, we report the synthesis of mesoporous carbon derived from nonporous MOFs without any heteroatom doping or residual metal, which is highly efficient for the electrocatalytic oxygen reduction reaction. The excellent ORR activity is attributed to both high specific surface area and mesoporous structure.
