Conducting temperature programmed methods involves several steps:
Preparation: The catalyst is prepared and loaded into a reactor or analysis chamber. Adsorption: For TPD, the gas of interest is adsorbed onto the catalyst surface at a controlled temperature. Temperature Ramp: The temperature is gradually increased at a controlled rate while monitoring the desorbed or reacted species using techniques like mass spectrometry, thermal conductivity detectors, or infrared spectroscopy. Data Analysis: The resulting data is analyzed to determine the characteristics of the catalyst, such as adsorption energy, reduction temperature, oxidation states, and reaction pathways.
