a XRD patterns of the reduced catalysts; b Ru K-edge EXAFS spectra of the reduced xZr/Ru samples; c, d HAADF-STEM images and STEM-EDS elemental mappings of the reduced 0.5Zr/Ru; e–h AC-HAADF-STEM images and elemental mappings of the reduced 0.5Zr/Ru sample. (Ru, Si, and Zr atoms are depicted in green, yellow, and red, respectively).
