Experimental study on VOCs adsorption by Zr-MOFs synthesized with different ligands
Journal Title: Energy Environmental Protection - Year 2023, Vol 37, Issue 3
Abstract
Zirconium-based MOFs adsorbent materials with different ligands, including: UIO - 66, UIO-66-NH_2, UIO-66-NDC and UIO-67 were hydrothermally synthesized using terephthalic acid as the base ligand and functionalized functional group ligands 2-aminoterephthalic acid, 1,4-naphthalenedicarboxylic acid and the long-chain ligand biphenyl dicarboxylic acid. The four adsorbent materials were characterized by XRD, FTIR and BET, and the adsorption performance on toluene and ethyl acetate was investigated. The results showed that all four MOFs with different ligands were successfully synthesized, and UIO-66 showed the best adsorption performance at a relative humidity of 80%, with toluene adsorption of 139.4 mg/g and ethyl acetate adsorption of 60.8 mg/g. The best adsorption performance of UIO-66 was attributed to its predominantly microporous pore size structure, showing good application potential. BET results showed that the micropore distribution was between 0.5~1 nm, which facilitated the adsorption of small molecule VOCs.
