what is a catalytic surface
The catalyst washcoat is a carrier for the catalytic materials, which is used to disperse the materials over a high surface area. Titanium dioxide, aluminium oxide, silicon dioxide, or a combination of silica and alumina can be used.The catalytic materials are suspended in the washcoat before application to the core. catalytic converter is a vehicle emissions control device that is used to convert toxic byproducts of combustion (occurring in the exhaust of an internal combustion engine) to less toxic substances by performing catalysed chemical reactions.
