How to Analyze the Results of Poisoning Tests?

The results of poisoning tests are typically analyzed by comparing the catalyst activity before and after exposure to the poison. Key metrics include:
Turnover Frequency (TOF): The number of reactions occurring at an active site per unit time.
Conversion Rate: The percentage of reactants converted to products.
Selective Deactivation: The change in selectivity towards desired products.
Analytical techniques such as Gas Chromatography (GC), Mass Spectrometry (MS), and X-ray Photoelectron Spectroscopy (XPS) are commonly used to analyze the effluent and the catalyst surface to identify the nature and extent of poisoning.
