Fig. 2 — a The fitted average formal d-band hole counts and b oxidation states of Pt from ∆XANES spectra, depicted with the calculated oxidation states of Pt₁-C₃N₁, Pt₁-C₂N₂, and Pt₁-C₁N₃ models. The oxidation state of Pt₁-C₃N₁ are the most proximate to that of the ex situ sample. c Corresponding k²-weighted Fourier transform (FT) spectra of Fig. 1e. d First-shell fitting of EXAFS spectra under ex situ, +0.15 V and −0.07 V conditions.
