•Overlapping the XPS Pt 4f and Cu 3p spectra of Pt-Cu alloys complicates its analysis.•XPS Cu 3p spectra were examined for all oxidation states of copper (Cu0, Cu+, Cu2+).•The Cu 3p spectra were then used for the precise fitting of Pt-Cu XPS Pt 4f spectra. The progress in the design of a perspective...
