Abstract (en)
[origin: FR2866249A1] Composition (C1) comprising gold on a cerium oxide support, with a halogen/gold molar ratio of 0.04 or less and a particle size of 10 nm or less, is new. Independent claims are also included for: (1) producing C1 by contacting cerium oxide with a gold halide and optionally a silver, platinum, palladium or copper compound at a pH of at least 8, separating solids and washing the solids with a basic solution; (2) producing C1 by depositing gold and optionally silver, platinum, palladium or copper on cerium oxide by impregnation or ion exchange and washing the product with a basic solution having a pH of at least 10; (3) oxidizing carbon monoxide using C1 as a catalyst; (4) purifying air containing carbon monoxide, ethylene, aldehydes, amines, mercaptans and/or volatile organic compounds, e.g. fatty acids, hydrocarbons (especially aromatic hydrocarbons) and malodorous compounds, by contacting the air with C1; (5) cigarette filter containing C1.
