Fig. 2. The electronic interaction between Pt and N-MoC. (a) The XANES spectra of Pt foil and Pt/N-MoC with 1 wt%, 2 wt%, and 5 wt% of Pt nanocluster. (b–d) The model that N-MoC supports different content of Pt nanocluster. The brown spherical represents C atoms, purple represents Mo atoms, white represents Pt atoms, and gray represents N atoms. The charge densities difference distribution of (e) Pt/N-MoC 1 Pt, (f) Pt/N-MoC 2 Pt, and (g) Pt/N-MoC 3 Pt, where the charge accumulation is shown in yellow and charge loss is shown in blue. The calculated PDOS (h) and d-band center (i) of Pt/N-MoC 1 Pt, Pt/N-MoC 2 Pt, Pt/N-MoC 3 Pt, and pure Pt.
