What are Common Methods to Test Catalyst Stability?
Assessing the stability of catalysts involves various testing methods, including:
Thermal Gravimetric Analysis (TGA): Measures weight changes as a function of temperature to evaluate thermal stability. X-Ray Diffraction (XRD): Analyzes structural changes in the catalyst over time. BET Surface Area Analysis: Monitors changes in surface area, which can indicate sintering or pore collapse. Activity Tests: Measures catalyst performance over extended periods to assess deactivation.
