What are the Effects of Aggregates on Catalytic Activity?
The presence of aggregates can have both positive and negative effects on catalytic activity. On the positive side, small aggregates can increase the surface area and the number of available active sites, enhancing the catalytic performance. On the negative side, large aggregates can lead to a decrease in surface area, blocking active sites and reducing the catalyst's effectiveness. Additionally, large aggregates may cause diffusion limitations, affecting the overall reaction rate.
