Zn-containing derivatives of H4SiMo12－nWnO40 (n＝2, 4, 6, 8, 10) were prepared under different pH according to the variation of n and characterized by elemental analysis, IR spectra, X-ray diffraction and XPS. The acid kind and intensity of the polyoxometalates were investigated by Py-IR and NH3-TPD, respectively. The polyoxometalates were used as heterogeneous catalysts in tested gaseous reaction of decomposition of isopropanol. The relationship between catalytic activity of the polyoxometalates and their component was discussed.

Key words: Keggin structure, polyoxometalate, isopropanol, zinc, catalysis
