CATALYST ON METAL SUBSTRATE BY SIMULTANEOUS ELECTROPHORETIC DEPOSITION OF CATALYST AND CATALYST ADHESION MATERIAL

摘要

Flexible metal foil catalyst members (7) suitable for use in catalytic devices for combustion engine emission control are prepared by electrophoretic deposition using an aqueous slurry (17) of catalyst support layer material and catalyst. The deposited layer (8) is of uniform thickness and stable surface area. The catalyst members (7) from the invention are especially suitable for use in automotive applications, and more especially in electrically-heated catalytic converters.
