What Techniques are Used to Study Surface Sensitivity?
Several advanced techniques are employed to study and characterize surface sensitivity in catalysis:
1. [Scanning Tunneling Microscopy (STM)](): Provides atomic-resolution images of the catalyst surface, revealing detailed information about surface morphology and defects. 2. [X-ray Photoelectron Spectroscopy (XPS)](): Used to analyze the elemental composition and chemical state of the surface, providing insights into surface reactivity. 3. [Temperature-Programmed Desorption (TPD)](): Measures the desorption of adsorbed species as a function of temperature, helping to understand adsorption energies and surface interactions. 4. [Density Functional Theory (DFT)](): Computational method that models the electronic structure of materials, predicting the catalytic behavior of different surface facets and defects.
