【 摘 要 】

The current study is devoted to the nitrogen doped carbons for application as fuel cell oxygen reduction catalysts, where wood char and highly porous activated carbons were used as precursors. Conditions of nitrogen introduction and its content in the carbonaceous material, as well as porous structure characteristics, such as specific surface and pore size distribution, were studied. It was found that the efficiency of doping reaction depends on the elemental oxygen content in the activated carbon. Relationships between nitrogen content, porous structure characteristics and electrodes electrochemical properties are demonstrated.
