What Information Can Be Obtained from In Situ TDS?
In situ TDS can provide a wealth of information, including: - Desorption temperatures: These indicate the strength of the adsorption interaction. - Desorption energies: These can be calculated from the desorption temperatures and provide insights into the nature of the surface interactions. - Reaction intermediates: By identifying the species desorbing at different temperatures, researchers can infer the presence of intermediates involved in the catalytic process. - Surface coverage: The amount of desorbed species can give an estimate of the surface coverage and adsorption capacity of the catalyst.
