What are the Methods of Assessing Catalytic Stability?
Evaluating the stability of a catalyst involves various techniques:
Activity Measurements: Monitoring changes in catalytic activity over time under standard operating conditions. Structural Analysis: Using techniques like X-ray diffraction (XRD) or electron microscopy to observe structural changes. Surface Characterization: Techniques like X-ray photoelectron spectroscopy (XPS) can provide insights into surface composition changes. Thermogravimetric Analysis (TGA): Assessing weight changes under controlled temperature conditions to study thermal stability.
