【Abstract】 Gold can be highly dispersed on metal oxides by coprecipitation and deposition-precipitation methods. The supported catalysts with gold particles below 5 nm are highly active for quite a few chemical reactions. The recent literature concerning oxidation of CO,hydrochlorination of ethyne, selective hydrogenation of crotonaldehyde, water-gas shift reaction and reduction of nitrogen oxides on supported gold catalysts is briefly reviewed in this article.更多还原
