Abstract

The present invention relates to a process for preparing TiO2/SiO2 mixed oxides or the hydrates and/or oxide hydrates thereof comprised of 0.5 to 95 wt % SiO2 and the balance as TiO2, each referring to the completely calcined product, by using titanium alcoholates and aqueous silica sol. Moreover, the invention relates to the use of these mixed oxides as catalyst carriers.
