a Pt L3-edge, (b) Pd K-edge, and (c) Ru K edge X-ray Absorption Near-Edge Structure (XANES) spectra. XANES of metallic Pt and PtO2 are shown in (a) as ref.37. XANES of metallic Pd and PdO are shown in (b) as ref.38. XANES of metallic Ru and RuO2 are shown in (c) as Ref.39. Source data for (a)–(c) are provided as a Source Data file.
