Several strategies can be employed to enhance the thermal stability of catalysts:
Material Selection: Choosing materials with high melting points and thermal stability, such as zirconia or titania, as supports. Support Modification: Modifying the support material to improve its thermal properties. For example, adding dopants like lanthanum to alumina can enhance its resistance to sintering. Structural Engineering: Designing catalysts with specific morphologies, such as mesoporous structures, to increase thermal resilience. Coating and Encapsulation: Coating active sites with thermally stable materials to protect them from thermal degradation.
