J0320603 金属ドープシリカ多孔質複合体の合成と構造解析([J032-06]ポリマー・セラミックス・メタル多孔質材料の開発と応用(6),材料力学部門)
詳細
Lanthanum (La) doping porous Silica (Si) material for adsorption of carbon dioxide (CO_2) was synthesized by a precursor solution method accessed the adsorption properties, and studied the relation between the microstructure and CO_2 adsorption properties by transmission electron microscopy (TEM), X-ray diffraction (XRD), automated gas sorption system (Autosorb). As a result, CO_2 adsorption of the Si-La materials exhibit better result at 373 K than at 673 K. The Si : La ratio 4:1 composite material showed best function of CO_2 adsorption as compare with Si : La=2:1 specimen, which suggested that CO_2 adsorption might depend on the surface site of activated La_2O_3 in Silica.
