CO2 adsorption by PAMAM dendrimers: Significant effect of impregnation into SBA-15

CO2 adsorption on Santa Barbara Amorphous-15 (SBA-15) and amine-modified Santa Barbara Amorphous-15 (SBA-15) with and without controlled microporosity

“…Various mesoporous silicas, such as MCM-41 [18,19], MCM-48 [20][21][22], pore-expanded MCM-41 [23,24], SBA-12 [25], SBA-15 [5,8,9,[26][27][28][29][30][31][32], SBA-16 [33], KIT-6 [34], HMS [35], mesocelullar silica foam [14,36], and mesoporous silica microspheres [37] were investigated. The influence of pore structure such as pore size [34], pore volume [27], pore length [38] and surface chemistry properties [5,39] of the support on CO 2 adsorption performance was studied.…”

Interaction of CO2 with Electron-Rich Moieties

“…To this end, ionic liquids and MOF (Metal Organic Framework) incorporating -NH 2 groups in their structure are also under study [33][34][35][36]. This method has also been extended to the use of multiple amine-containing dendrimers [37,38]. The dynamic CO 2 -amine chemistry has been successfully exploited for the reversible formation of organogels by exposing solutions of some long-chain alkylamines to CO 2 [39,40] or to build up supramolecular polymers [41,42].…”

Octa(aminophenyl)silsesquioxane fabrication on chlorofunctionalized mesoporous SBA-15 for CO2 adsorption

“…The CO 2 adsorption capacity of Cl-SBA-15/10% OAPS is 2 wt.% (20 mg/g of adsorbent), and further increasing the OAPS loading, the adsorption capacity increases. Specifically, 6. internally hydrogen-bonded similar to PAMAM dendrimer [41] and, therefore, unavailable to interact with CO 2 . The CO 2 adsorption capacity of Cl-SBA-15/50% OAPS is comparable with the already reported CO 2 sorbents like zeolite 13X (90.2 mg/gadsorbent at 25°C) and PEI (80 mg/g of sorbent) [42,43].…”
