Various materials are used for coatings, depending on the application and desired properties. Common materials include:
- Alumina (Al2O3): Known for its high surface area and thermal stability. - Silica (SiO2): Often used for its inert properties and ability to disperse active metals. - Titania (TiO2): Useful for its photocatalytic properties and stability. - Zeolites: Microporous aluminosilicates known for their shape-selectivity and acidity.
These materials can be tailored to support specific active metals like platinum, palladium, rhodium, or nickel, enhancing their catalytic performance.
