Abstract :KIT-6 is a mesoporous material with cubic la3d symmetry, adjustable porous 3-dimensional insert ignore into journalissuearticles values(3D); silica structure, advanced wall thickness and excellent thermal stability. KIT-6, with its cubic la3d symmetrical structure, has adjustable pore size and excellent thermal/hydrothermal stability. In this study, characterization studies of Cu/KIT-6 material by preparing different Si/Cu: blank, 1, 3, 5 ratios were performed by SEM, SEM-Mapping, TEM, XRD, N2 adsorption-desorption, FTIR analysis. Cu based la3d mesoporous silica KIT-6 was synthesized by hydrothermal method and different silicon to copper insert ignore into journalissuearticles values(Cu); ratios nSi/Cu: 1, 3, 5 and blank KIT-6 were investigated for CO2 adsorption capacity at ambient conditions. The highest CO2 adsorption of 1.70 mmol CO2/g at 0°C and 1.2 bar was achieved for nSi/Cu:1 ratio Cu/KIT-6. These materials are thought to be useful for the emission of CO2 that causes global warming.
