The preparations of lithium zirconate (Li_2ZrO_3) powders were attempted by a sol-gel process. This material reacted immediately with CO_2 in the range from an ambient temperature to 873K. Moreover, the products react and revert reversibly to Li_2ZrO_3 at temperature above 973K. The absorption and emission of CO_2 gas were ascribed to the mechanism whereby lithium oxide in the Li_2ZrO_3 react reversibly with CO_2. The degree of absorption was defined as the value obtained by dividing the fractional mass gain of Li_2ZrO_3 after absorption by the fractional mass gain corresponding to 100% reaction. The degree of absorption of Li_2ZrO_3 powder having a specific surface area of 9.81m・g^<-1> attained to 95.2% under the absorption condition at 773K for 7.2ks. Furthermore the controls of micropore size for anodic oxide film prepared by Kalcolar solution were attempted by a vacuum heating and a sol-gel process and. The permeation characteristics of CO_2-N_2 mixtured gas through the membrane were evaluated. The ability of CO_2 gas separation using this membrane was confirmed.

尝试通过溶胶-凝胶法制备锆酸锂(Li_2ZrO_3)粉末，该材料在室温至873K范围内立即与CO_2反应，并且在高于973K的温度下反应并可逆地还原为Li_2ZrO_3。和CO_2气体的排放归因于Li_2ZrO_3中锂氧化物的机理与CO_2发生可逆反应的吸收度定义为吸收后Li_2ZrO_3的质量增量除以100%反应对应的质量增量所得到的值，即比表面积为​的Li_2ZrO_3粉末的吸收度。 ​9.81 m・g^<-1> 在773K 7.2ks的吸收条件下达到95.2%。进一步控制微孔尺寸通过真空加热和溶胶-凝胶法制备了Kalcolar溶液制备的阳极氧化膜，并评价了CO_2-N_2混合气体透过膜的渗透特性，证实了该膜对CO_2气体的分离能力。
