How Can We Characterize HEAs for Catalysis?

Characterizing HEAs involves a combination of techniques to assess their composition, structure, and catalytic performance. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) are commonly used to analyze the structural and chemical properties of HEAs. Additionally, temperature-programmed desorption (TPD) and in-situ spectroscopy techniques can provide insights into the catalytic mechanisms and active sites.
