Role of additives in silica-supported polyethylenimine adsorbents for CO2 adsorption
SiO _2 aerogels were prepared by sol-gel method and methyl alkylation reaction using TEOS as silicon sources. Silica-supported polyethylenimine (PEI/SiO _2 ) adsorbents for CO _2 adsorption were prepare by grafting techniques, in which mesoporous SiO _2 aerogel was loaded with PEI and organic compou...
