Nitrogen-doped carbon materials (NCs) are extensively studied for the oxygen reduction reaction (ORR). However, the nature of active sites of pyridinic nitrogen (N<sub>P</sub>) or graphitic nitrogen (N<sub>G</sub>) on NCs is still under debate. Herein, we demonstrated that the ORR activity of NCs in alkaline media depended on the electronic synergism between N<sub>P</sub> and N<sub>G</sub>, rather than any single type of N. We measured the transferable electrons of NCs by absorption spectroscopy ...[more]
