Abstract:

Exploration of low-cost and high-performance oxygen reduction reaction (ORR) electrocatalysts to replace Pt-based catalysts is now undergoing fast and dynamic development. Metal-free carbon-based ORR electrocatalysts have interesting catalytic activities, high stabilities, and good CO and methanol tolerances, and their constituents are abundantly available. They are therefore potential 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 perspectives are speculated for this new kind of promising metal-free ORR electrocatalysts.
