Catalyst longevity can be assessed through several methods:
- Catalytic Activity Tests: Measuring the activity of a catalyst over time under controlled conditions can provide insights into its longevity. - Spectroscopic Techniques: Methods such as X-ray diffraction (XRD) and infrared (IR) spectroscopy can monitor changes in the catalyst's structure and composition. - Microscopic Analysis: Techniques like scanning electron microscopy (SEM) can reveal physical changes at the micro or nanoscale that may affect longevity.
