Abstract
PURPOSE: To obtain a monolith catalyst having high activity, thermal stability and resistance to poisonous materials by forming an α-alumina film having macropores uniformly on the surface of a carrier as a catalyst for purification of waste gases.
CONSTITUTION: An aqueous composition prepd. by adding fine powder of γ- alumina, δ-alumina or the like to the alumina sol stabilized with an inorg. or org. acid is stuck uniformly on a carrier such as honeycomb structure, after which it is dried and is calcined at 1,000W1,300°C. Then, an α-alumina film is formed on the surface of the carrier, after which the catalyst component such as platinum or rhodium is deposited thereon, whereby the catalyst for purification of waste gases is obtained. In this way, the highly active three element catalyst is produced.
