A porous ceramic or metallic coating applied to catalyst substrates to increase surface area and support active catalytic materials.
The washcoat layer is a critical component in catalytic converters and industrial catalysts, consisting of a high-surface-area material (typically gamma-alumina, ceria-zirconia, or other metal oxides) applied as a slurry to the substrate surface. This layer provides the physical support structure for precious metal catalysts (platinum, palladium, rhodium) or base metal catalysts, enabling efficient catalytic reactions by maximizing active surface exposure while maintaining thermal stability and mechanical integrity under operating conditions.

The washcoat layer provides a high-surface-area support structure that maximizes the dispersion of precious metal catalysts, enabling efficient conversion of exhaust pollutants while maintaining thermal and mechanical stability.
Washcoat composition determines surface area, thermal stability, oxygen storage capacity, and interaction with active metals. Optimal formulations balance these properties for specific catalytic applications and operating conditions.
Common failures include thermal sintering (reduced surface area), phase transformation, mechanical detachment, pore blockage from contaminants, and chemical poisoning from sulfur or phosphorus compounds.
