In the first year, the functionalized artificial material will be fabricated using nano-casting and sol-gel route. Natural minerals will also investigate and pretreat for further experiments. To properly utilize the natural and artificial material in application with high performance, the influence of the fabrication parameters on the properties of the prepared materials, such as geinetries, crystallinity, and shapes, will be investigated using FE-TEM、FE-SEM/EDX、XRD、UV-Vis、ICP、Raman、XPS、XAS、FT-IR etc. In the second year, the surface modification of functionalized artificial material such as amine grafting, Li-series oxides will use to increase their surface area and carbon absorption capacity. Meanwhile, natural minerals will also investigate their physical chemical properties. The functionalization of the natural mineral and functionalized artificial material on the above prepared and pretreated materials will be carried out for the changed pressure and temperature carbon absorption system to investigate the carbon absorption capacity and their possible physical chemical reaction. In the third year, the carbon absorption kinetic model and assessment will also investigate to establish the carbon absorption data base of functionalized artificial material and natural mineral in Taiwan. We estimate the data base will support information for further studies of carbon reuse and/or sequestration.二氧化碳捕集中孔洞氧化矽中孔洞碳材天然礦石carbon dioxidecapturemesoporous silicamesoporous carbonnatural minerals
