Thermal stabilizers work through several mechanisms:
1. Inhibition of Sintering: They prevent the agglomeration of catalyst particles, which can lead to a loss of surface area and active sites. 2. Phase Stabilization: They maintain the desired phase of the catalyst material, preventing unwanted transformations that can reduce activity. 3. Protection from Poisoning: Some stabilizers can shield the catalyst from contaminants that can deactivate it.
