Abstract

A process for the preparation of a TiO2-containing catalyst or catalyst support which is stable to high temperatures is described. In this process Alternatively, the TiO2-containing catalysts or catalyst supports which are stable to high temperatures can be prepared by a process in which 1. hydrated precursors of one or more metal oxides or semi-metal oxides and 2. hydrated titanium oxide are rapidly precipitated from aqueous solution.
