The importance of chemical inertness in catalysis cannot be overstated. Inert supports help in: 1. Stabilizing the Catalyst: Preventing the active species from agglomerating or degrading. 2. Enhancing Activity: By providing a large surface area for dispersion of the catalyst. 3. Preventing Side Reactions: Ensuring that the support does not participate in unwanted side reactions that could diminish the catalyst's effectiveness.
