Tailoring zeolites for enhanced post-combustion CO2 capture: A critical review

Fossil combustion mainly contributes to global warming and increases atmospheric CO₂ levels, an essential greenhouse gas and environmental risk. The atmospheric CO₂ level increased, emphasizing the necessity to restrict the emission while maintaining it out of the carbon cycle. Various porous adsorbents were created as CO₂ capture sorbents, but they have been just moderately successful and require upgrading with more efficient porous adsorbents to address global climate issues caused by CO₂. Due to their tunable pore sizes, high chemical stability, superior adsorption selectivity, and large surface area, zeolite-based adsorbents are considered promising materials for CO₂ capture. Their framework structures allow for molecular sieving, ion exchange, and surface modifications, further enhancing their adsorption efficiency and regeneration capability.
