Fig. 1. (a) Low-magnification TEM image of the Ag@Pt core/shell nanoplates. Inset: a model of the nanostructure. (b) Moiré fringes observed from a single Ag@Pt core/shell nanoplate. (c) HAADF-STEM image of the Ag@Pt core/shell nanoplates. Inset: profile of the intensity across a nanoplate along the white line as indicated in the image. (d) EDS elemental mapping of a single Ag@Pt core/shell nanoplate.
