Several strategies can be employed to control the pore size distribution of catalysts:
- Synthesis Methods: Techniques such as sol-gel processing, templating, and hydrothermal synthesis allow precise control over pore size. For example, the use of surfactants as templates can create mesoporous structures. - Post-Synthesis Modification: Methods like calcination, acid treatment, and metal deposition can modify the pore structure after the catalyst has been synthesized. - Composite Materials: Combining materials with different pore structures can result in a composite catalyst with a tailored pore size distribution.
