1. Vacuum Packaging: Removes air and moisture, ideal for air-sensitive catalysts. 2. Inert Atmosphere Storage: Uses inert gases like argon or nitrogen to protect catalysts from air and moisture. 3. Refrigeration or Freezing: Used for temperature-sensitive catalysts, particularly biocatalysts. 4. Desiccators: These are sealed containers with a drying agent to maintain a low-humidity environment.
