Abstract：Polyoxometalate (POM)-based materials universally have some inherent flaws, including low recovery, metastability, solubility, etc., which may restrict their practical applications. Modifying the materials with organic-inorganic hybrid complexes is one of the most effective approaches to overcome these deficiencies. Under hydrothermal conditions, a new Wells- Dawson-type polytungstate modified Cd-complex, [Cd(phen)3]3[W18O54(PO4)2]•3H2O (1, phen = 1,10-phenanthroline (C12N2H8)), has been synthesized by selecting Cd2+ coordinated phen and employing stepwise self-assembly plans. The compound shows good stability and water- insolubility under normal circumstances. Experiments demonstrate that compound 1 has ideal catalytic activity in the degradation reaction of rhodamine B (RhB) under ultraviolet (UV)-light and oxidant H2O2 conditions. Detailed characterizations including X-ray single-crystal diffraction (XRD), Powder X-ray diffraction (PXRD), elemental analysis, energy-dispersive X-ray spectroscopy (EDS) analyses, Fourier transform infrared spectroscopy (FT-IR), UV-Vis-NIR diffuse reflection spectrum (DRS) and XPS spectrum are presented herein. The electrochemical (cyclic voltammetry (CV)) and photocatalytic properties of 1 have also been studied.
