Several strategies can be employed to enhance the thermal stability of catalysts:
Material Selection: Choosing materials with high melting points and inherent thermal stability, such as certain metal oxides and ceramics. Support Interactions: Utilizing supports that can stabilize the active phase and prevent sintering, such as high surface area alumina or silica. Doping: Adding small amounts of other elements (dopants) to the catalyst can enhance thermal stability by modifying its structural and electronic properties. Core-Shell Structures: Designing catalysts with a core-shell structure can protect the active core from sintering and other high-temperature effects.
