Abstract
The invention relates to a method of producing Pd/Au-containing supported catalysts by CVD (chemical vapor deposition) of vaporizable Pd/Au precursors. For this purpose, suitable noble metal precursors are vaporized and deposited on porous support bodies and subsequently reduced thermally or chemically to the metal and thereby fixed to the support. In particular, the invention relates to the production of Pd/Au coated catalysts on porous supports by this method. The supported catalysts produced in this way can be used for many heterogeneously catalyzed reactions such as hydrogenations and oxidations. Pd/Au coated catalysts produced by this method can, according to the invention, be used in the synthesis of vinyl acetate.
