Abstract

Graphical abstract: A 1D Co-based MOF has been prepared, presenting good catalytic activity and cyclicity in the CO2 conversion with epoxides. Highlights: A 1D Co-based MOF has been synthesized and structurally characterized. The 1D Co-based MOF has good thermostability and pH stability. The 1D Co-based MOF has good catalytic activity and cyclicity. Abstract: A 1D MOF {[Co(XN)(HCOO)2 (H2 O)2 ]}n (1 ) was harvested by solvothermal method with organic ligand XN (4′-(4-pyridine)4, 2′:2′, 4′'-terpyridine), and structurally characterized by single-crystal X-ray diffraction, PXRD and TGA. Structural determination demonstrates that compound 1 owns zigzag shape framework through the infinite connection of Co 2+ ion and XN ligand. Moreover, it can resist 240 °C and various acid/alkali solutions, presenting good thermostability and pH stability. Catalytic performance indicates that compound 1 can efficiently catalyze the CO2 cycloaddition with styrene oxide at 80 °C and 0.1 MPa with the addition of 5% mol TBAB for 12 h. Especially, compound 1 can keep stable framework and almost unchanged catalytic activity after five catalytic recyclings.
