Conducting a TPD experiment involves several steps:
Sample Preparation: The catalyst sample is typically pre-treated to remove any impurities and to activate its surface. Adsorption: A known amount of probe molecule is adsorbed onto the catalyst surface at a controlled low temperature. Temperature Ramp: The temperature is linearly increased at a predetermined rate, causing the adsorbed species to desorb. Detection: The desorbed species are detected and quantified using appropriate detectors. Data Analysis: The TPD spectrum is analyzed to derive information about the adsorption sites and their binding energies.
