What Are the Common Techniques Used in Catalytic Imaging?
Several techniques are employed in catalytic imaging, each with its own strengths and limitations:
Transmission Electron Microscopy (TEM): Offers high-resolution images of catalyst structures and can provide information about the size, shape, and distribution of nanoparticles. Scanning Electron Microscopy (SEM): Provides surface morphology details and elemental composition through energy-dispersive X-ray spectroscopy (EDS). Atomic Force Microscopy (AFM): Useful for studying catalyst surfaces at the atomic level and measuring surface forces. X-ray Photoelectron Spectroscopy (XPS): Allows for the analysis of surface chemical states and elemental composition. Infrared (IR) Spectroscopy: Used to identify functional groups and study reaction intermediates on catalyst surfaces.
