Interestingly, our Pt-5d PDOS trends cannot be linked to both previous theoretical literature and experimental evidence, as both seem to predict inverted trends, i.e. a decrease of intensity close to the Fermi energy with a diffuse increase in intensity for lower states. A DFT study of Verga et al. investigated various oxygen coverages using DFT on perfect nanoparticles, and showed that the density of states clearly shift to lower energies as the oxygen ratio increases, without the presence of a narrow peak below the Fermi energy.
