There are several reasons why silica gel is often chosen as a support material:
1. High Surface Area: The large surface area provides more active sites for catalytic reactions. 2. Thermal Stability: It can withstand high temperatures, making it suitable for various industrial processes. 3. Chemical Inertness: Silica gel is chemically inert and does not interfere with the catalytic process. 4. Customizability: The porosity and surface characteristics can be tailored to suit specific catalytic needs.
