How are Colloidal Catalysts Characterized?

Characterization of colloidal catalysts is essential to understand their properties and performance. Techniques include:
Transmission electron microscopy (TEM): Provides information on size and shape of nanoparticles.
X-ray diffraction (XRD): Used to determine the crystalline structure of nanoparticles.
Dynamic light scattering (DLS): Measures the size distribution of nanoparticles in colloidal solutions.
UV-Vis spectroscopy: Analyzes the optical properties and concentration of nanoparticles.
X-ray photoelectron spectroscopy (XPS): Provides surface chemical composition and oxidation states.
