“…According to literature, the typical binding energies of Pt in the form of Pt metal, PtO, and PtO2 species appears at ca. 71, 72.4, 74.9 eV, respectively [28][29][30][31][32]. Considering the Pt/TiO2 prepared by PDC-MSD, the shift in XPS peaks due to Pt metal towards lower binding energy, as compared to the value reported in the references, could be attributed to several factors.…”
