Abstract (en)

[origin: WO03068389A1] The invention relates to metal-oxide supported Au catalysts with a narrow cluster size distribution and a high degree of dispersion for the Au cluster. Said catalysts are obtained by drying moist Au/metal-oxide catalyst precursors, obtained in a known manner, by means of co-precipitation, precipitation or impregnation and by reducing the dried precursors in the gaseous phase using H2 or CO at temperatures of </= 250 DEG C. The inventive catalysts are suitable for the selective CO oxidation in reformer gases (PROX), the low-temperature water-gas shift reaction (WGS), the synthesis of methanol, the epoxidation of olefins, or the total oxidation of CO, hydrocarbons or halogenated gases (VOC).
