- W994241569 abstract "Supported Au/Fe 2 O 3 and Au/TiO 2 catalysts appear very active in both carbon monoxide oxidation by oxygen or water. The aim of this work was to find correlation between gold catalysts activity and methods of their preparation (impregnation and deposition-precipitation), the influence of alkali ions additives and temperature of calcination. The physico-chemical properties of Au/Fe 2 O 3 and Au/TiO 2 catalysts were investigated by TPR, ToF-SIMS and catalytic activity methods. Carbon monoxide conversion degree in oxidation by oxygen is higher for Au/Fe 2 O 3 than for Au/TiO 2 catalyst, but the activity of gold catalysts in carbon monoxide oxidation by water is opposite. The most active catalyst was Au/Fe 2 O 3 prepared by deposition-precipitation method with an addition of urea and those catalysts prepared by impregnation method with an addition ofKOH. The analogically prepared Au/TiO 2 catalyst exhibited comparable activity. The gold catalysts appear the most active after drying at 60°C - the role of disordered catalyst structure and hydroxyl groups. The carbon monoxide conversion degree depends on the applied precipitate agent in the following order: KOH > Na 2 CO 3 > NH 3 . The gold catalysts do not lose catalytic activity during long lasting tests (170 h) and do not suffer on the presence of moisture and chlorine in catalyst system. The impregnated Au(K)/Fe 2 O 3 catalysts with a ratio Cl/Au = 4/1 - 8/1 show considerable activity." @default.
