Figure 14. (A) HAADF-STEM with diameter histogram and (B) high-magnification TEM for Te-Pd NCs; (C) PXRD for Pd NCs and Te-Pd NCs. (i and ii) PXRD patterns enlarged from (C); (D) HRTEM for Te-Pd NCs from eectangular region in (B); (E) HAADF-STEM as well as elemental mappings of Te-Pd NCs. Reprinted with permission from ref^[22].
