Several materials are commonly used for coating catalysts, including:
Metal Oxides: Materials such as alumina, silica, and titania are often used due to their high surface area and stability. Noble Metals: Metals like platinum, palladium, and rhodium are used for their excellent catalytic properties. Zeolites: These microporous, aluminosilicate minerals can be used to enhance selectivity and provide shape selectivity. Carbon-based Materials: Graphene and carbon nanotubes can be used for their high surface area and electrical conductivity.
