The novel route of preparation of the supported gold catalysts by deposition-precipitation

Au/SiO2 and Au/TiO2 catalysts were prepared by the original procedure of depositionprecipitation with ammonia. As compared with the previously published methods, the proposed procedure makes possible almost complete deposition (>99%) of gold from HAuCl4 solution on the SiO2 and TiO2 supports at t...

Zusammenfassung:Au/SiO2 and Au/TiO2 catalysts were prepared by the original procedure of depositionprecipitation with ammonia. As compared with the previously published methods, the proposed procedure makes possible almost complete deposition (>99%) of gold from HAuCl4 solution on the SiO2 and TiO2 supports at the low ratio NH3:Au = 6.5–7 and pH
