The selection of reference catalysts is based on several criteria:
Stability: The catalyst should be chemically and thermally stable under the reaction conditions. Reproducibility: It should provide reproducible results across different laboratories and experimental setups. Characterization: It must be well-characterized using techniques like X-ray diffraction (XRD), transmission electron microscopy (TEM), and BET surface area analysis. Commercial Availability: Ideally, it should be commercially available to ensure widespread use.
