Abstract (en)
[origin: WO9851401A1] The invention relates to a gold catalyst for oxidation of carbon monoxide and hydrocarbons, reduction of nitrous oxides and degradation of ozone, for use in the protection of the environment. The active component of the catalyst consists of complex of gold and reducible oxide from the group of the transition metals. The concentration of gold in the catalyst is from 0.1 % to 2.5 % and the total concentration of the metals in the active component of the catalyst is from 0.1 % to 10 % of the total mass. The support consists of oxides of ceria and titanium. The surface of the catalyst is between 80 m<2>/g and 400 m<2>/g and the catalyst working temperature is from 0 DEG C to 400 DEG C.
