The introduction of heteroatoms into carbon materials has been widely used to boost the surface reactivity of carbon materials. Unlike nitrogen extensively investigated, the influence of boron in the synthesis of porous carbon materials has not been comprehensively understood. In this study, we successfully synthesized the heteroatom (boron, nitrogen, and/or oxygen)-doped highly nanoporous carbon materials via the chlorination process of carbonitride-boride starting materials. Boron dopants paly the roles of carbon structure linkers, which are the keys to alter the characteristics of porous carbon. This enabled to produce carbon materials enriched with reactive sites responsible to oxidation stability and electrochemical properties. Oxygen-rich carbide-derived carbon and nitrogen-rich carbonitride-derived carbon materials were synthesized through the present chlorination method, and they show the enhanced oxygen reduction reaction (ORR) catalytic performance. |
