Catalytic stability is typically measured through long-term reaction tests where the catalyst is subjected to operating conditions over extended periods. Key metrics include:
Activity Retention: The ability of the catalyst to maintain its activity over time. Selectivity: The ability of the catalyst to maintain its selectivity towards desired products. Structural Integrity: Monitoring changes in the catalyst’s physical and chemical structure using techniques such as X-ray diffraction (XRD) or transmission electron microscopy (TEM).
