What are the Challenges in Controlling Size Distribution?
Controlling the size distribution of catalyst particles presents several challenges:
Synthesis Techniques: Achieving uniform particle sizes during synthesis can be difficult and may require precise control over reaction conditions. Aggregation: Small particles tend to aggregate, which can alter the effective size distribution. Sintering: High temperatures can cause particles to grow larger over time, changing the size distribution. Characterization: Accurate measurement of size distribution requires advanced techniques, which can be costly and time-consuming.
