Several materials are commonly used as stationary phases in catalysis:
1. Silica: Known for its high surface area and porosity, silica is often used in acid-catalyzed reactions. 2. Alumina: Generally employed for its basic properties, alumina is useful in a variety of oxidation and hydrogenation reactions. 3. Activated Carbon: With its high surface area and adsorption capacity, activated carbon is suitable for reactions involving organic compounds. 4. Zeolites: These microporous materials are excellent for shape-selective catalysis due to their well-defined pore structures. 5. Metal-Organic Frameworks (MOFs): These offer tunable porosity and chemical functionality, making them versatile for various catalytic applications.
