There are various methods employed to ensure controlled storage of catalysts:
1. Sealed Containers: Using airtight containers can prevent exposure to air, moisture, and contaminants. This is crucial for catalysts that are sensitive to oxidation or humidity.
2. Vacuum Storage: For highly sensitive catalysts, vacuum storage can be an effective method to eliminate exposure to air and moisture.
3. Refrigeration and Freezing: Temperature-sensitive catalysts are often stored in refrigerators or freezers to slow down any potential degradation processes.
4. Inert Atmosphere Storage: Storing catalysts in a glove box filled with an inert gas like nitrogen or argon can protect them from air-sensitive degradation.
