Removal of Typical Industrial Gaseous Pollutants: From Carbon, Zeolite, and Metal-organic Frameworks to Molecularly Imprinted Adsorbents

In recent years, various adsorbents have been developed to alleviate atmospheric pollution and remove harmful gases, such as carbon dioxide, sulfur dioxide, nitrogen oxides, hydrogen sulfide and volatile organic compounds. Polymer-based adsorbents are a novel type of material now being used for gas separation and purification; in particular, molecular imprinted polymers (MIPs) can achieve selective adsorption of target gas molecules. However, existing review papers have not yet discussed the application of MIPs in gas purification. In this paper, therefore, we exhaustively summarize recently developed adsorbents, including the materials based on carbon, zeolite, and metal-organic frameworks as well as MIPs, to analyze the status of these materials and identify promising adsorbents for gas purification.
