The use of solid adsorbents for CO2 capture is importance in the development technologies to remove this greenhouse gas. High surface area mesoporous materials are used encapsulate or functionalize amines that selectively CO2. MCM-41 class hexagonally ordered silicas have areas between 1000 and 1500 m2/g, which principle allows a significant degree when such as polyethyleneimine (PEI) encapsula...
