What are the Challenges in Characterizing Particle Size and Shape?
Characterizing the particle size and shape of catalysts poses several challenges. Techniques such as Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD) are commonly used. However, these techniques require sophisticated equipment and expertise. Additionally, interpreting the data can be complex, particularly for non-uniform or irregularly shaped particles.
