4)  X-ray photoelectron spectroscopy (XPS) related to figure 3


This dataset details the elemental composition and distribution of each component for C, W and Mo based on high-resolution measurements and a survey of carbon model electrodes. The files consist of two columns: Intensity (a.u.) and Binding Energy (eV), along with the specific contributions of each element. The data is compatible with analysis using CasaXPS software.
