To ensure the longevity and effectiveness of catalysts, follow these storage guidelines: 1. Air-tight Containers: Use air-tight containers to prevent exposure to air and moisture. 2. Cool, Dry Place: Store catalysts in a cool, dry place to prevent degradation. 3. Away from Contaminants: Keep catalysts away from potential contaminants. 4. Labeling: Clearly label containers with the type of catalyst and any special handling instructions.
