Abstract

The present invention relates to the use of a catalyst in a catalytic combustion, which catalyst is produced by the coating of a carrier with a suspension of noble metal particles in a microemulsion. The carrier is distributed on a monolith. The invention also relates to a catalyst comprising an active phase which by microemulsion technique has been deposited on a carrier. The active phase comprises noble metal particles. The carrier comprises a metal oxide and is distributed on a monolith. The invention also relates to a method of producing a catalyst as defined above by microemulsion technique, wherein bimetallic particles are produced by the blending of not reduced noble metal particles in microemulsion and then the reduction thereof.
