Fig. 2. Characterization of Ru1-Co3O4. (a, b) XRD pattens, (c) depth-profiling XPS spectra, CPS (counts per second), (d) atomic ratio of Ru determined by XPS, and (e) HAADF- STEM image of Ru1-Co3O4. The inset shows the corrsponding FFT image. (f) Magnified image of the boxed area in (e), where yellow circles highlight monodispersed Ru atoms. (g) Intensity profile corresponding to the labeled line in (f). (h) EDS-mapping image. (i) Ru 2p XPS spectra. (j) X-ray absorption near edge structure (XANES) spectra and (k) Fourier-transformed EXAFS spectra of Ru-K edge.
