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 increase the CO2 capture capability are highlighted. We also briefly discuss the future prospects of porous carbons for CO2 capture.
