发明名称 PROCESS FOR PRODUCING TENSIDE-STABILIZED COLLOIDS OF MONO- AND BIMETALS OF THE GROUP VIII AND IB OF THE PERIODIC SYSTEM IN THE FORM OF PRECURSORS FOR CATALYSTS WHICH ARE ISOLABLE AND WATER SOLUBLE AT HIGH CONCENTRATION
摘要 The invention relates to a process for producing tenside-stabilized colloids of mono- and bimetals of the group VIII and Ib of the periodic system which are isolable in the form of powder and which are soluble at a concentration of at least 100 mg atom of metal/l of water, from metal salts in the presence of strongly hydrophilic tensides with hydrotriorganoborates in THF, or with simple chemical reduction agents like hydrogen or alkali formate in water and alcohols, respectively. Furthermore, the subject matter of the invention is the use of the tenside-stabilized colloids which are produced according to this process as precursor for supported catalysts for the selective cishydrogenation of C-C triple bonds, for the selective hydrogenation of functional groups at the aromatic nucleus, for the selective hydrogenation of benzene to cyclohexene, for the partial oxidation of the primary alcohol functionality in carbohydrates, as well as for use as a precursor for electrocatalysts in fuel cells.
