Ionic liquid post-modified carboxylate-rich MOFs for efficient catalytic CO₂ cycloaddition under solvent-free conditions

Abstract

Synthesis of cyclic carbonates from the cycloaddition reaction between epoxides and carbon dioxide (CO2) is an important industrial process. Metal-Organic Frameworks (MOFs) have functional and ordered pore structures, making them...

Recent Uses of Ionic Liquids in the Recovery and Utilization of Rare Earth Elements

“…One approach to enhance the catalytic activity of metal organic frameworks (MOFs) in CO2 cycloaddition reactions is to create open metal sites within MOFs [79]. Thus, the amino-functionalized rare earth Gd-MOF (Gd-TPTC-NH2) and its ionic liquid composite catalysts (Gd-TPTC-NH-[BMIM + ][Br -]) were synthesized using 2′-amino-[1,1′:4′,1′′-terphenyl]-3,3′′,5,5′′-tetracarboxylic acid (H4TPTC-NH2) as the ligand.…”
