Protection: Coatings can protect the catalyst from deactivation mechanisms such as sintering, poisoning, and fouling. Enhanced Activity: Coatings can enhance the catalytic activity by providing additional active sites or improving the dispersion of active components. Improved Selectivity: Coatings can modify the surface properties of the catalyst, leading to improved selectivity towards desired products. Thermal Stability: Coatings can improve the thermal stability of catalysts, allowing them to operate at higher temperatures without degradation.
