The invention relates to polyoxometalates represented by the formula (A)[M(HO)XWO(OH)]or solvates or mixtures thereof, wherein A represents a cation, n is the number of the cations, m is the charge of the polyoxoanion, M represents a transition metal selected from Pd, Pt and mixtures thereof, y is 1, 2, 3 or 4, p is the number of water molecules bound to one M and varies from 3 to 5, and X represents a heteroatom selected from Sb, Bi, As, Seand Te, a process for their preparation and their use for the catalytic oxidation of organic molecules.

Pd- and Pt-substituted polyoxometalates and process for their preparation

The invention relates to supported polyoxometalates represented by the formula (A)[M(HO)(XWO)]or solvates thereof, wherein A represents a cation, n is the number of cations, m is the charge of the polyoxoanion, M is a transition metal, and X is an element selected from the group consisting of As, Sb, Bi, Se and Te, characterized in that the polyoxometalate is supported on a solid support selected from the group consisting of AlO, MgO, TiO, ZrO, SiO, mesoporous silica, active carbon, diatomite, clays, zeolites, polyoxometalate salts and mixtures thereof, with the proviso that the polyoxometalate salt supports are different from the supported polyoxometalates defined by the above formula, a process for their preparation and their use for the catalytic oxidation of organic molecules.
