How are Results from Accelerated Aging Tests Analyzed?
The results are analyzed using various characterization techniques:
- BET Surface Area Analysis: Measures changes in surface area. - X-ray Diffraction (XRD): Identifies phase changes. - Temperature-Programmed Reduction (TPR): Assesses changes in reducibility. - Electron Microscopy: Visualizes structural changes at the nanoscale.
These techniques help correlate physical and chemical changes with performance degradation, providing insights into deactivation mechanisms.
