What Types of Studies Benefit from UHV Conditions?
Several types of studies in catalysis benefit from UHV conditions:
1. Surface Characterization: Techniques like X-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) require UHV conditions to provide detailed information about the surface composition and structure. 2. Reaction Mechanisms: Investigating the elementary steps of catalytic reactions, such as adsorption, desorption, and surface diffusion, under UHV helps in understanding the reaction mechanisms. 3. Model Catalysts: UHV conditions allow for the preparation and study of model catalysts, which are idealized systems that mimic the complexity of real catalysts but in a more controlled manner.
