Abstract: A ternary platinum alloy catalyst on a conductive carbon carrier for use in fuel cells is disclosed. For the production of the catalyst, nitrate salts are used as precursors of the alloy components and all alloy components are deposited concurrently on the carbon carrier. This method of procedure yields ageing-stable catalysts with high oxygen mass activity.

Abstract: The invention relates to a process for the selective catalytic hydrogenation of the carbonyl group of aromatic aldehydes of the formula in which X can be a carboxyl group, a methyl group or halogen, to give the corresponding alcohols and methyl compounds. The catalytic hydrogenation is carried out with the addition of a solvent, if appropriate in the presence of organic acids, on a shaped supported catalyst containing a metal from the platinum group on a titanium oxide support in the presence of hydrogen at partial pressure of hydrogen of 5 to 50 bar and temperatures of from 100 to 300@C.
