We planted to design a solid sorbent in order to provide a solution to solve huge carbon dioxide amount release from power plant, steel plant etc., to atmosphere. The alkali metal oxide inside mesoporous micrometer ball we prepare with good sintering-resisted property can apply to capture carbon dioxide from flue gas for multi cycles. The prepared sorbent will be investigated by various instruments such as TEM-EDS, FESEM, XRD,UV-Vis, ICP, Raman, XPS, XAS, BET, in order to understand structure properties and chemical properties, and try to realize the reaction mechanism. Finally, we use LCA tools to make sure all procedure to be environmentally friendly.二氧化碳捕集鹼性金屬氧化物環境友善carbon dioxide capturealkali metal oxidemesoporous micrometer ballenvironmentally friendly.
