Designed porous carbon materials for efficient CO₂ adsorption and separation

The emission of CO₂ from industry and power plants has become a worldwide problem with a strong link to global warming. The development of novel materials for efficient CO₂ capture and utilization is attracting worldwide attention as a hot topic in materials sciences. Among various CO₂ adsorbents, porous carbons have proven competitive by virtue of their high specific surface area, tunable pore and surface structures, moderate heat of adsorption, and less sensitivity to humidity than other CO₂-philic materials. In this review, we summarize the recent significant advances in porous carbon materials for CO₂ adsorption and separation. Strategies to increasethe CO₂ capture capability are highlighted. We also briefly discuss the future prospects of porous carbons for CO₂ capture.
