The materials used in compounding can vary widely depending on the specific application. Common materials include:
- Metallic Catalysts: Metals like platinum, palladium, and nickel are often used for their high catalytic activity. - Metal Oxides: Compounds such as titanium dioxide and alumina are used as supports to disperse the active catalytic species. - Zeolites: These microporous, aluminosilicate minerals are used for their ability to act as molecular sieves and acid catalysts. - Promoters: Substances like potassium or sulfur are added to improve the performance of the primary catalyst.
