Several types of materials are commonly used as catalysts:
Metals: Platinum, palladium, nickel, and gold are widely used in various catalytic processes. Metal Oxides: Titanium dioxide, cerium oxide, and zinc oxide are examples of metal oxides used as catalysts. Zeolites: These microporous, aluminosilicate minerals are used extensively in petrochemical industries. Enzymes: Biological catalysts that facilitate biochemical reactions within living organisms. Nanomaterials: Materials like carbon nanotubes and graphene offer unique catalytic properties due to their high surface area and electronic properties.
