There are several types of coatings commonly used in the field of catalysis:
Metallic Coatings: These are often used to protect the catalyst from oxidation and corrosion. Examples include platinum, palladium, and nickel coatings. Ceramic Coatings: Known for their thermal stability and resistance to chemical attack, ceramic coatings like alumina and zirconia are frequently used. Polymeric Coatings: These coatings can provide a barrier to moisture and other contaminants, extending the life of the catalyst.
