摘要：The rapid rise in carbon dioxide (CO2) levels in the atmosphere is a major cause of climate deterioration. Human activities, particularly over the past two centuries, have caused a substantial 50% increase in CO2 concentrations. This rise is directly linked to increasing the global temperatures and acid rain. CO2 capture using porous materials, such as mesoporous silica, is a promising mitigation approach because of its exceptional characteristics for instance, high pore volume, high surface area, and low cost. The KIT-5 is distinguished for its distinct 3-D, cubic structure with Fm3m symmetry. In this study, KIT-5 mesoporous silica was first synthesized via hydrothermal synthesis process and then was functionalized with Tetraethylenepentamine (TEPA) through an impregnation technique. The KIT-5 was analysed by different advanced characterization techniques i.e. X-ray Diffraction analysis (XRD), Fourier Transform Infrared Spectroscopy (FTIR) and Surface area porosity analysis (SAP). Characterization techniques revealed that the synthesized KIT-5 exhibited distinguished mesoporous for its well-defined cubic la3d structure and well-tunable pore size. After functionalization, the TEPA_KIT-5 showed almost the similar structure as that of the KIT-5, Ultimately, the KIT-5 and the TEPA_KIT-5 were subjected to CO2 adsorption study at 3 bar pressure and room temperature. KIT-5 showed 0.49 mmol-CO2/g-adsorbent capacity and TEPA_KIT-5 showed an adsorption capacity of 0.82 mmol-CO2/g, which was 67.3% higher than that of KIT-5.
