Pre drying serves several purposes: 1. Moisture Removal: It eliminates any water content that could deactivate the catalyst or affect its activity. 2. Solvent Removal: Residual solvents from synthesis processes can be removed to avoid unwanted side reactions. 3. Enhancing Stability: The removal of moisture and solvents helps in stabilizing the catalyst structure. 4. Improving Performance: Drying can enhance the physical and chemical properties of the catalyst, leading to better performance.
