| Carbon dioxide (CO2) is considered to be the major greenhouse gases that have a direct impact on the world's atmosphere. It is critical that effective capture and storage materials be developed to reduce the amount of carbon dioxide in the atmosphere. As is well known, CO2 was believed to be a Lewis acid. So, the solid base, MgAl-complexs oxide might act as a potential CO2 basket for CO2 storage and conversion. Therefore, the adsorption behavior of CO2 over such oxide was investigated by means of CO2-TPD and in-situ FTIR to have a deep insight into CO2 capture. The results of CO2-TPD and FT-IR revealed that the surface of MgAl-complex oxide existed weak basic sites and medium basic sites originated from the surface hydroxyl groups and acid-base pairs which favorite the adsorption and desorption of carbon dioxide. The thermodynamic of adsorption was also investigated using a vacuum adsorption apparatus. |
