Abstract


Amine-functionalized mesoporous silica has attracted much attention as a promising chemical sorbent for capturing carbon dioxide. It has the combination of several features viz., high adsorption capacity, high selectivity toward CO, fast kinetics, mild conditions for desorption and should be stable under operating conditions. In this study, a chemical grafting route has been developed to synthesize mesoporous adsorbents with amines functionalization for CO capture. The initial silylation step was achieved by grafting of different silane linkers (3-aminopropyl)-trimethoxysilane (APS) and 3-chloropropyl)-trimethoxysilane (CPS) via direct condensation and hydrolysis reaction. After silylation the CPS-supports was reacted with tris(2-aminoethyl)amine (TREN) to introduce the amine group to increase the adsorptive capabilities for these sorbents. The synthesized sorbents were characterized by N2 adsorption/desorption, XRD, FTIR and HR-SEM. The adsorption capacities of the modified solid sorbents show a significant enhancement in their adsorption capacity by 3-4 times higher than that of the parent materials which indicate the affirmative impact of amines for CO adsorption after grafting.
