On the Origin of Electrocatalytic Oxygen Reduction Reaction on Electrospun Nitrogen-Carbon Species |
| 초록 |
Nitrogen-doped carbon (N-C) is a promising alternative electrocatalyst for oxygen reduction reaction (ORR) to replace the expensive Pt, but the origin of electrocatalytic ORR activity of various N-C materials is still unclear. In this study, we show our facile approach to the synthesis of highly active metal-free N-C catalyst with the chemical treatments including hydroxide activation and complete metal leaching. Through the detailed investigation on the origin of ORR electrocatalysis for electrospun N-C nanofibers, we revealed that pyrrolic-N and highly graphitized carbon are mainly responsible for the enhanced ORR activity of metal-free N-C nanofiber and embedded Co metal is involved in the creation of the pyrrolic-N site. |
