| Popis: | A 1D MOF {[Co(XN)(HCOO)2(H2O)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 Co2+ 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. |
