In this study, oxygen-containing functional groups were introduced into the carbon skeleton to improve its properties. Air preoxidation can not only introduce oxygen-containing functional groups, but also pretreat coal tar pitch by removing light aromatic components to form a cross-linking network to improve its pore structure. It also helps KOH impregnation to achieve uniform contact with the carbon source, thereby obtaining a uniform pore structure. The optimized material OPC-600 was successfully synthesized. In contrast to preoxidation methods using strong oxidants such as H₂O₂ or HNO₃, which involve safety risks and environmental concerns, the air preoxidatiACS omega63414-63425https://www.ebi.ac.uk/biostudies/studies/S-EPMC12756743biostudies-literatureCoal Tar Pitch Preoxidation-Impregnation Regulates Pore Distribution to Prepare Porous Carbon for Electrochemistry.PMC12756743He YLiu LXue CJia RLu CHao HYang CWang JSu HLi MfalseCoal Tar Pitch Preoxidation-Impregnation Regulates Pore Distribution to Prepare Porous Carbon for Electrochemistry.Enhancing the performance of porous carbon materials has become a key focus in current research.
