| Abstract: | A series of UiO-66 metal-organic frameworks(MOFs) with excellent stability was used to prepare metal-organic aerogels as a feasible way for the modeling of MOFs. The as-prepared UiO-66-based metal-organic aerogels(MOAs) possessed hierarchical pore structure and high surface area, which were very promising in gas adsorption and separation applications. In gas adsorption measurements, the amine modified UiO-66-NH2 aerogel exhibited outstanding adsorption capacity towards CO2 and high selectivity up to 18.3 towards CO2/CH4 mixture(molar ratio, 1∶1) calculated through ideal adsorbed solution theory. |
