چکیده مقاله:

Carbon dioxide (CO2) adsorption on unfunctionalized and amino-functionalized SBA-3 materials are investigated and compared in this study. The synthesized materials are characterized by varioustechniques such as X-ray diffraction (XRD), Brunauer-Emmet-Teller (BET) method, Fourier transforminfrared (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 bymesoporous silica was enhanced through functionalization with amine groups. It is observed that thepentaethylene hexamine functionalized SBA-3 (SBA-3/PEHA) possessed a higher adsorption capacity towards CO2 than that of the other adsorbents
