Synthesis of 3D Cadmium(II)-Carboxylate Framework Having Potential for Co-Catalyst Free CO2 Fixation to Cyclic Carbonates

Metal-organic frameworks (MOFs) are porous coordination polymers with interesting structural frameworks, properties, and a wide range of applications. A novel 3D cadmium(II)-carboxylate framework, CdMOF ([Cd2(L)(DMF)(H2O)2]n), was synthesized by the solvothermal method using tetracarboxylic bridging linker having amide functional moieties. The crystal structure exists in form layer structure. Based on single-crystal X-ray diffraction studies, supramolecular assembly is explored Hirshfeld surface analysis. voids cavities analysis performed to check strength packing CdMOF. followed multistage thermal degradation pattern which solvent molecules escaped around 200 °C framework remained stable till 230 °C. main collapsed (>60 wt.%) into organic volatiles between 400–550 SEM morphology analyses revealed uniform wedge-shaped rectangular blocks dimensions 25–100 ?m. catalytic activity for cocatalyst-free cycloaddition CO2 epichlorohydrin successful 100% selectivity. current results that this more active than previously reported CdMOFs and, interestingly, without co-catalyst. catalyst easily recovered reused, same performance.
