Outline of Final Research Achievements

Effect of functional groups on the peformance of UiO-66 membranes was investigated. amino and carboxy groups could be successfully functionalized on the UiO-66 membrane without large defects. Amino-functionalized UiO-66 membrane (UiO-66-NH2) showed very high CO2 permeance with a moderate CO2 selectivity over N2 and CH4. Interestingly, this membrane demonstrated comparable CO2 separation performance even under a wet condition to the performance under a dry condition. Thus, UiO-66-NH2 membrane is expected to be a promising candidate for CO2 separation membrane.
Postsynthetic modification by organosilanes on UiO-66 was investigated. Organosilane modification on UiO-66 resulted significant change in the adsorption property of UiO-66. Organosilica modification would be a simple and powerful method for controlling the adsorption performance of UiO-66.
