While catalyst dilution offers several benefits, it also comes with challenges:
1. Loss of Activity: Diluting the catalyst often leads to a decrease in the overall activity, which may require longer reaction times or higher temperatures. 2. Complexity in Optimization: Finding the right balance between dilution and activity can be complex and may require extensive experimentation. 3. Material Costs: The use of inert diluents adds to the material costs, especially if the diluent is a high-purity substance.
