Several techniques can be used to assess catalyst quality. These include:
1. BET Surface Area Analysis: Measures the surface area of the catalyst, which is directly related to its activity. 2. X-ray Diffraction (XRD): Determines the crystalline structure and phase purity, which can affect stability and selectivity. 3. Temperature-Programmed Desorption (TPD): Assesses the type and strength of active sites on the catalyst surface. 4. Thermogravimetric Analysis (TGA): Evaluates the thermal stability of the catalyst. 5. Spectroscopic Techniques: Methods such as FTIR and NMR provide insights into the chemical environment and active sites.
