a TEM image of the synthesized RuPt nanoparticles (scale bar, 50 nm). The inset shows the diameter histogram. b TEM image of the supported catalysts (scale bar, 50 nm). c HAADF-STEM image of a representative RuPt nanoparticle (scale bar, 1 nm). d EDS mapping of a representative RuPt nanoparticle (scale bar, 1 nm). e, f Fourier transforms of EXAFS spectra of Pt L3-edge (e) and Ru K-edge (f). g, h XPS spectra of Ru 3p (g) and Pt 4f (h) for RuPt nanoparticles before and after reduction.
