There are several methods to control pore size in catalyst materials:
1. Template Synthesis: Using templates like surfactants, polymers, or hard templates to create pores of specific sizes. 2. Sol-gel Process: Adjusting the hydrolysis and condensation rates of precursors to control pore formation. 3. Post-synthesis Treatment: Techniques such as calcination, acid/base treatment, and chemical vapor deposition (CVD) to modify pore sizes after the initial synthesis.
