Abstract A novel polyoxometalate, ［Et3N］5［H3BW12O40］2·2H2O(1, CCDC: 932 982), was prepared by hydrothermal method, using Et3N, Na2WO4·2H2O, H3BO4 and Cu(NO3)2 as materials. The structure and properties were characterized by UV-Vis, FT-IR, elemental analysis, XRD, XPS, TGA and CV. The results showed that 1 was in 3D supramolecular structure. The weight loss ratio of 1 was 15.53% at 602 ℃. The results of 1 catalytic degradation methyl orange indicated that 1 exhibited good photocatalytic property. The degradation ratio decreased to 41.6% from 100% with degradation rate of 11.68%·h-1.
