“…Recently, efforts have been made to optimize the amine phase with other additives to obtain adsorbents having higher CO 2 adsorption capacity [14,15]. In this paper, PEI modified SiO 2 aerogels were grafted with different additives from amine functional groups and hydroxyl groups and emphatically the effects of the seven additives on CO 2 adsorption capacity were investigated and evaluated.…”

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 compounds functionalized by hydroxyl or amino groups as dopants. CO 2 adsorption isotherms of PEI amine-modified SiO 2 aerogels were measured and the results show that the maximum CO 2 adsorption capacity (1.8 mmol g −1 ) was obtained over a doped SA-PEI-N-Y loaded with 45% PEI and 15% N-Y (N-[3-(Trimethoxysilyl)propyl]ethylenediamine, denoted as N-Y). In addition, SA-PEI-N-Y has stronger thermal stability than SA-PEI-60% in nitrogen from room temperature to 800°C at a heating rate of 10°C min −1 . It turns out that N-[3-(Trimethoxysilyl)propyl]ethylenediamine is the best dopant.
