Abstract: Microporous heteropolyoxometalates CsxH5-xPW10V2O40SiO2 were synthesized by a solgel technique and characterized by IR, UV-Vis, BETadsorption/desorption isotherm. The structural frameworks of CsxH5-xPW10V2O40 are preserved within the silica networks. CsxH5-xPW10V2O40SiO2 are a kind of polyoxometalatesilica gel hybrids with uniform micropores of ca. 0.65 nm. They show a high catalytic activity for oxidation reaction of benzyl alcohol by H2O2(30) in liquid-solid systems and product selectivity for benzaldehyde(>96). The highest activity is observed at x=2.5 in CsxH5-xPW10V2O40SiO2 and little formation of benzoic acid and a more deeply oxidized product is observed.
