Although platinum and platinum alloys (e.g. PtNi and PtCo) are widely regarded as the best catalysts for the oxygen reduction reaction (ORR) at present, they are expensive and still suffer from technical drawbacks. Recently, the exploration of Pt-free or even metal-free ORR catalysts including heteroatom-doped carbon nanomaterials is very active in the electrochemistry and carbon research communities. Previous investi-gations have employed five main dopant elements (i.e. nitrogen, boron, phosporus, sufur, and selenium). In this study, we explore a new set of dopant atoms (alkali, alkaline earth, and halogen atoms) for the two-dimensional graphene structure for possible ORR electrocatalytic application.
