Electron-induced effects, which are prevalent in adsorption and heterogeneous catalytic reactions, can significantly influence the state uptake of adsorbates. Here, we demonstrate situ doping electron-deficient boron into backbone chitosan-based porous carbon materials. Despite a reduction specific surface area, resulting boron-doped carbons (NBPCs) exhibit an enhanced CO2 performance, with sample NBPC-10 achieving capacities 7.62 4.82 mmol·g–1 at 273 298 K, respectively. This improvement is attributed to electron-induced effect doping, also enhances separation selectivity from N2. Additionally, high capacity fosters synergism between NBPCs cocatalyst tetrabutylammonium bromide (TBAB), thereby augmenting activity for cycloaddition epoxide. Notably, cyclic carbonate yields exceeding 99% were attained even under 1 bar CO2. Controlled experiments corroborated pivotal role boron-doping-induced modifications structure enhancing both selective conversion performance. Furthermore, demonstrated excellent recyclability as adsorbents catalysts, offering fresh perspectives design functionalized materials tailored capture conversion.
