Measuring active site density can be challenging and often requires sophisticated techniques. Some common methods include:
BET Surface Area Analysis: This method involves measuring the surface area of the catalyst to estimate the number of active sites. Chemisorption: This technique measures the amount of gas adsorbed onto the catalyst surface, providing insights into the number of active sites. Spectroscopic Methods: Techniques like IR spectroscopy or NMR can offer detailed information about the nature and number of active sites.
