Abstract
The invention relates to a gold-based composition on a cerium oxide-based support having a halogen content with respect to a molar halogen/gold ratio equal to or less than 0.04, wherein the gold is embodied in the form of particles whose size is equal to or less than 10 nm. Said composition is made by a method consisting in bringing a cerium oxide-based compound into contact with a gold halide-based compound, thereby forming the suspension thereof, the thus obtained medium pH being fixed to a value of at least 8, subsequently, in separating a solid from a reaction medium and in washing said solid with a basic solution. The inventive composition can be used in the form of a catalyst in carbon monoxide oxidation methods, for treating tobacco smoke and air.
