Active sites of nitrogen-doped carbon materials for …
The oxygen reduction reaction is an important step in fuel cells and other electrochemical processes but is still largely dependent on precious metal-containing alysts. Recently explored alternatives include carbon materials that are doped with different, preferably non-precious metal, atoms. Guo et al. studied model graphite alysts to try to understand the role of nitrogen doping and to
