What Are the Key Types of Materials Used in Catalysis?
Catalytic materials can broadly be classified into several categories, each with its unique properties and applications. These include:
1. Metals and Alloys: Transition metals like platinum, palladium, and nickel are commonly used due to their high catalytic activity. 2. Metal Oxides: Materials such as titanium dioxide and cerium oxide are often used in oxidation reactions. 3. Zeolites and Porous Materials: These materials offer high surface areas and unique pore structures that are beneficial for various catalytic processes. 4. Organometallic Complexes: These are used primarily in homogeneous catalysis for specialized chemical transformations. 5. Hybrid Materials: Combining different types of materials can lead to synergistic effects that enhance catalytic performance.
