摘要：

For the purpose of finding the catalytic active site for the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER) in the crystal structure of Co3O4, a {100} faceted Co3O4 cube enclosed by only a Co2+ site and a {112} faceted Co3O4 plate also exposing a Co3+ site was adopted as a catalyst for lithium-oxygen (Li-O-2) batteries. Thus, we found that the Co3+ site plays the crucial role of determining the adsorption properties of reactants, enabling high round-trip efficiency and cyclic stability, as well as the morphology of discharge products such as Li2O2.
