Popis: | Herein, a new 3D POMOF [{Cl4Cu10(pz)11}{As2W18O62}]·1.5H2O (pz = pyrazine) (1) has been synthesized using a hydrothermal reaction, and characterized by single-crystal X-ray diffraction analysis, elemental analysis, IR, TG, and UV-vis-NIR spectroscopy, XPS, BET analysis and XRD. Single crystal X-ray analysis reveals that compound 1 consists of the classical Wells–Dawson [As2W18O62]6− polyoxoanion and {Cl4Cu10(pz)11} complexes. Compound 1 possesses two different channels which form a 3D topology framework with the Schlafli symbol of {3·4·56·67}2{3·46·53}2{32·42·56·65}. Additionally, compound 1 shows photoluminescence properties and excellent photocatalytic activity for the degradation of RhB dye under UV irradiation. The photocatalytic reaction kinetics and mechanism have been also investigated. |
