摘要: A mesoporous UiO-66-NH2 aerogel is prepared via a straightforward sol–gel method without using any binders or mechanical pressures, in which the amine groups are directly introduced into the matrix by using 2-aminoterephthalic acid. The novel UiO-66-NH2 aerogel also exhibits high specific surface area and mesopore-dominated structure, implying its highly potential use in CO2 adsorption. For ulteriorly investigating the effect of amine loading on the CO2 adsorption ability, a series of UiO-66-NH2 aerogel with different amino content is fabricated by changing the ligand/metal molar ratio. When the molar ratio is 1.45, the CO2 adsorption capacity reaches the optimum value of 2.13 mmol·g-1 at 25 ℃ and 0.1 MPa, which is 12.2% higher than that of pure UiO-66 aerogel. Additionally, UiO-66-NH2-1.45 aerogel also has noticeable CO2 selectivity against N2 and CH4 as well as good regeneration stability. Such results imply that it has good application prospect in the field of CO2 adsorption, and also contains the potential to be applied in catalysis, separation and other fields.
