Among them, heteroatom-doped graphene-based materials show extraordinary electrocatalytic performance, some even close to or outperforming the state-of-the-art noble metals, such as Pt- and IrO₂- based materials. This review provides a concise appraisal on graphene doping methods, possible doping configurations and their unique electrochemical properties, including single and double doping with N, B, S, and P. In addition, heteroatom-doped graphene-based materials are reviewed as electrocatalysts for oxygen reduction, hydrogen evolution, and oxygen evolution reactions in terms of their electrocatalytic mechanisms and performance. Significantly, three-dimensional heteroatom-doped graphene structures have been discussed, and those especially can be directly utilized as catalyst electrodes without extra binders and supports.en© 2015 American Chemical SocietyHeteroatom-doped graphene; nonnoble electrocatalysts; oxygen reduction reaction; hydrogen evolution reaction; oxygen evolution reactionJournal article003003471110.1021/acscatal.5b009910003610897000292-s2.0-84941095599210348Qiao, S.
