The synthesized materials are characterized by various techniques such as X-ray diffraction (XRD), Brunauer-Emmet-Teller (BET) method, Fourier transform infrared (FT-IR) and Scanning electron microscopy (SEM).The isotherms of these materials have been measured using volumetric method at 298 K up to 5 bar. The adsorption capacity of CO2 by mesoporous silica was enhanced through functionalization with amine groups. It is observed that the pentaethylene hexamine functionalized SBA-3 (SBA-3/PEHA) shows a higher adsorption capacity towards CO2 compared to other adsorbents.
