Abstract
Six new complexes alpha-M6-mHm [SiW11(TiO2)O-39] . xH(2)O, alpha - M(1 0-m)Hm [SiW9 (TiO2)(3)O-37] . xH(2)O and alpha-M6-mHm [SiW11TiO40] . x H(2)O(M = K,TBA) were synthesized and characterized by IR and UV spect roscopy, polarography and cyclic voltammetric, W-183 NMR, XPS and XRD methods. The experimental results indicate that they are all the Keggi n structure and the reduced electric potential of the complexes arise over -3.0V with entering of TiO2 groups. This complexes had high activ ity for the epoxidation of Maleic acid using H2O2 oxidant.
