Erratum to: Synthesis, Structure, Characterizations and Photocatalytic Degradation of a New POM-Based Hybrid Compound: (Hdma)4[Cd(phen)3][W18O54(PO4)2]·2H2O

Polyoxometalates are widely employed as multifunctional materials, but often limited in further applications due to their metastability and solubility in solution. Employing stepwise self-assembly program and “combining” organic–inorganic hybrid units ([Cd(phen)3]2+) with Wells–Dawson-type inorganic polyanions result in a new steady and water-insoluble hybrid polytungstate, (Hdma)4[Cd(phen)3][W18O54(PO4)2]·2H2O (1) [dma = dimethylamine (C2NH7), phen = 1′10-phenanthroline (C12N2H8)]. Experiments demonstrate that compound 1 shows good catalytic activity in the degradation reaction of rhodamine B under UV-light and oxidant H2O2 conditions. Detailed characterization include single-crystal X-ray diffraction (XRD), elemental analysis, thermogravimetric, powder-XRD, infrared spectroscopy, energy-dispersive X-ray spectrometry analyses, UV–Vis–NIR diffuse reflection spectrum and X-ray photoelectron spectroscopy. The electrochemical (cyclic voltammetry) and photocatalytic properties of 1 have also been studied.
