Metal-free car- bon-based ORR electrocatalysts have interesting catalytic activities,high stabilities,and good CO and methanol tolerances,and their constituents are abundantly available.They are therefore poten- tial alternatives to Pt-based catalysts.This paper briefly reviews the main progress in this emerging field,in combination with studies performed by our group.Special attention is paid to electron-rich N or electron-deficient B mono-/co-doped carbon nanostructures,and the correlation between the ORR activity and the electronic structure of the sp2 carbon material.The bright perspec |
