There are several reasons to use a carrier for catalysts:
Increased Surface Area: The carrier material typically has a high surface area, which allows for a greater dispersion of the active catalytic species, thereby increasing the overall catalytic activity. Enhanced Stability: Carriers can improve the thermal stability of the catalyst, preventing sintering and deactivation at high temperatures. Improved Selectivity: The interaction between the catalyst and the carrier can enhance the selectivity towards desired products. Ease of Handling: Supported catalysts are often easier to handle, separate, and recover from reaction mixtures.
