This review focuses on the precise regulation of pore structures in porous carbon materials for CO₂ capture. It systematically summarizes pore construction strategies including precursor design, templating, and activation methods, and elucidates the ideal pore architecture features conducive to CO₂ adsorption, with emphasis on the synergistic advantages of microporous/mesoporous structures for adsorption capacity and CO₂/N₂ selectivity .
