Figure 1

Morphological and structural features of the b-Pd@Rh-NCs. (a) Overview SEM, (b) low- and (c) high-magnification TEM, (d) HAADF-STEM, and (e) HRTEM images of the b-Pd@Rh-NCs. The insets in panel (a), (d), and (e) show a high-magnification SEM image, the HAADF-STEM-EDS elemental mapping images, and the corresponding FFT image, respectively. The arrows in inset (a) indicate the square cross section of branches. (f) Powder XRD pattern of the b-Pd@Rh-NCs. The intensities and positions for the pure Pd (cyan, JCPDF no. 05–0681) and Rh (orange, JCPDF no. 05–0685) references are presented as different colorful bars at the bottom according to the JCPDS database.
