Several materials are employed in advanced coatings for catalytic applications:
1. Metal Oxides: Materials like alumina, silica, and titania are commonly used for their thermal stability and ability to disperse active metal particles. 2. Noble Metals: Platinum, palladium, and gold are often used as coatings due to their excellent catalytic properties and resistance to poisoning. 3. Ceramics: Advanced ceramics like zirconia and ceria are used for their high-temperature stability and oxygen storage capacity. 4. Polymers: Polymers can be used as coatings to provide flexibility, resistance to chemical attack, and ease of processing.
