Several issues can arise if catalysts are not stored properly:
Deactivation: Exposure to air, moisture, or contaminants can deactivate catalysts, making them less effective. Agglomeration: Fine catalyst particles can clump together if not stored properly, reducing their surface area and effectiveness. Thermal Degradation: Some catalysts can degrade if exposed to high temperatures over long periods. Oxidation: Metal catalysts, in particular, are prone to oxidation, which can severely impact their activity.
