ammonia temperature programmed desorption (tpd)

What Information Can Be Obtained from Ammonia TPD?

The data obtained from ammonia TPD can provide several key insights:
Acid Site Strength: By examining the temperature at which ammonia desorbs, one can determine the strength of the acid sites.
Acid Site Density: The amount of desorbed ammonia indicates the density of acid sites on the catalyst.
Type of Acid Sites: The desorption profile can help differentiate between Brønsted and Lewis acid sites.
