【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 metalorganic 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.更多还原
