摘要: Abstract Amine-impregnated mesoporous silica materials were prepared using surface-modified supports for CO2 capture, and the effects of surface chemical structure support on adsorption performance silica-supported amines investigated systematically. The thermal stability characteristics amine-impregnated determined experimentally. modification silicas by particular functional groups leads to increases in loaded amine capacity. In particular, presence water vapor was remarkably enhanced support. Computational analyses indicated that capacity due hydrophilicity electron donativity (nucleophilicity) introduced groups. Compared non-modified support, capacities supported increased up 118% absence 182% vapor. It is suggested plays an important role performance.
