Fig. 1

a TEM image of the SAs Rh-CeO2 NWs. b AC-HAADF/STEM image in temperature color of the SAs Rh-CeO2 NWs. The isolated Rh atoms are marked with black circles. c The intensity profile recorded from the line in panel (b). d AC-HAADF/STEM image in temperature color of the Rh/CeO2 NWs. The Rh cluster is marked with blue line. e The intensity profile recorded from the line in panel (d). f, g Rh K-edge XANES spectra (f) and Rh K-edge EXAFS spectra in R space (g) of the Rh foil, Na3RhCl6, Rh2O3, SAs Rh-CeO2 NWs, and Rh/CeO2 NWs. The scale bars in (a), (b), and (d) are 100, 2, and 2 nm, respectively.
