Well-dispersed Pt/RuO-decorated mesoporous N-doped carbon as a hybrid electrocatalyst for Li-O batteries.

Despite their high energy density, the poor cycling performance of lithium-oxygen (Li-O) batteries limits their practical application. Therefore, to improve cycling performance, considerable attention has been paid to the development of an efficient electrocatalyst for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Catalysts that can more effectively reduce the overpotential and improve the cycling performance for the OER during charging are of particular interest.
