Abstract
Disclosed is a method of coating a porous carrier layer of metal-metal oxide and depositing an active catalyst component on metal substrates, and a monolith module useful as a catalytic reactor with low pressure drop prepared using the metal substrate having the deposited catalyst. By forming the porous carrier particle layer on the metal substrate and depositing the catalyst particles thereon, the catalyst particles are drastically increased in deposition strength and impact durability. Also, the disclosed monolith catalyst module is used for a long time while the catalyst is not detached under high mechanical or thermal impact and high conversion efficiency thereof is maintained at a desired level, due to securely deposited catalyst particles.
