A critical review on new and efficient adsorbents for CO2 capture

Carbon dioxide (CO2) is the main anthropogenic greenhouse gas that causes global warming and has a huge impact on the global ecosystem. In order to reduce the impact of carbon dioxide emissions from human society on the entire earth's ecological environment, researchers have conducted in-depth research on various new materials for CO2 capture. Metal organic Frameworks (MOFs), porous organic polymers (POPs), ionic liquids (ILs), and deep eutectic solvents (DESs) have garnered the attention of researchers worldwide. Factors including the specific surface area, physical and chemical properties and surface modification of the adsorbent material play a vital role in the carbon dioxide adsorption process. This review summarizes and evaluates the physical and chemical properties of MOFs, POPs, ILs and DESs and their effects on carbon dioxide capture performance. Although these materials have shown progress in carbon dioxide capture, further research is needed to develop cost-effective and sustainable adsorption materials for large-scale applications.
