Several techniques can be employed to achieve improved dispersion:
1. Impregnation Method: This involves soaking the support material in a solution containing the active component. After soaking, the material is dried and calcined to achieve uniform distribution. 2. Co-Precipitation: Both the support and the active component are precipitated simultaneously from a solution. This method is often used for creating mixed metal oxides. 3. Deposition-Precipitation: A precursor of the active component is precipitated onto the support material, followed by filtration, washing, and calcination. 4. Sol-Gel Method: This involves the formation of a colloidal solution that transitions into a gel. The active components are incorporated into the gel, leading to high dispersion.
