Preparing catalyst samples involves several steps to ensure uniformity and reproducibility:
Synthesis: Methods like precipitation, impregnation, and sol-gel are commonly used. Characterization: Techniques such as X-ray diffraction (XRD), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) surface area analysis are employed. Activation: Heat treatment or reduction processes are often necessary to activate the catalyst.
