Carbon dioxide (CO2) is the main greenhouse gases emitted today. Metal-Organic Framework (MOF) materials are crystalline materials with two or three-dimensional porous structures composed of metal center and/ or metal clusters connected by organic linker. Carbon dioxide adsorption on metal-organic framework material, chromium terephthalate (MIL-101) and MIL-101 modified with 3-Aminopropyltriethoxysilane (APTS), investigated in this study. At first, we synthesized these adsorbents and then were characterized by Brunauer- Emmet- Teller (BET), X-Ray diffraction (XRD) and Fourier transform infrared (FT-IR) analysis. CO2 adsorption capacity was measured by volumetric method. MIL-101 and APTS-MIL-101 exhibited CO2 adsorption capacity of 0.85and 1.3 m.mol CO2.g-adsorbent-1, respectively, at 10 bar and 298 K. CO2 adsorption capacity enhanced about 50 % after amine modification.
