The present invention relates to an amorphous titanium stannate silicate with the general formula: Mv+ wTixSiySnzO2x+2y+2z+0.5vw, wherein M is proton, ammonium, a metal or a mixture of metals, wherein v is the valence of M being a positive integer, and wherein x, y, z and w are molar ratios: x is 1, y is from 0.01 to 99, z is from 0.01 to 99, and w is from 0.01 to 50. The described titanium stannate silicates are particularly useful in catalysis and adsorption. |
