Mixed metal oxide catalysts suitable for the production of alcohols from carbon monoxide and hydrogen are prepared by: (a) forming a solution of the metals in a polar organic solvent, (b) precipitating the metals from the solution either in the form of their oxides or a form thermally decomposable to the oxides, (c) calcining the precipitate to form the oxides and remove thermally decomposable components therefrom, and (d) where an anion other than oxide remains from step (c) removing same from the precipitate. Suitable polar organic solvents are ketones, esters, ethers and alcohols, particularly C1 to C10 alcohols. Preferably, the precipitated metals are washed with water to remove anions other than oxide. The method is particularly suitable for the production of catalysts containing metals such as uranium which are difficult to precipitate from aqueous solution.
