What Methods are Used to Measure Catalyst Stability?
Catalyst stability is evaluated through:
- Long-term Reaction Studies: Continuously running the reaction for extended periods and periodically measuring the activity and selectivity. - Thermogravimetric Analysis (TGA): Measures changes in weight as a function of temperature to assess thermal stability. - X-ray Diffraction (XRD): Monitors changes in the crystalline structure of catalysts under reaction conditions.
