Scanning transmission electron microscopy (STEM) of Pt-decorated Co-Pd. a Atomic-scale high angle annular dark field-STEM (HAADF-STEM) image of as-prepared Pt-decorated Co-Pd (Co@Pd-Pt) nanocatalyst. Yellow and red arrows indicate the decorated Pt species and the unconformable Pd shell regions, respectively. Scale bar: 1 nm. b–d EDS elemental maps of the Co@Pd-Pt nanocatalyst in a
