TPD can provide several key pieces of information about a catalyst:
Desorption energy: The temperature at which a particular gas desorbs can be related to the strength of its interaction with the surface. Active site distribution: Peaks in the TPD spectrum can indicate the presence of different types of active sites on the catalyst surface. Surface coverage: The area under the desorption peaks can be used to estimate the amount of gas adsorbed on the surface. Reaction mechanisms: By analyzing the TPD spectra of various adsorbed species, researchers can gain insights into the mechanisms of catalytic reactions.
