Several strategies can be employed to control the size distribution of catalyst particles:
Precise Synthesis Methods: Techniques such as sol-gel, hydrothermal synthesis, and controlled precipitation can help in obtaining uniform particle sizes. Stabilizing Agents: The use of surfactants or stabilizers can prevent aggregation and maintain a consistent size distribution. Temperature Control: Careful control of synthesis and reaction temperatures can minimize sintering and particle growth. Post-Synthesis Treatment: Techniques such as milling or sonication can be used to adjust the particle size distribution after synthesis.
