Figure 2

(a) TEM (inset) and scanning electron microscope images of PtFe-on-shell isolated nanoparticle (SHIN) core–shell-satellite nanocomposites. Scale bar, 100 nm. Scale bar for the inset, 20 nm. (b) Element maps of the single particle in the inset of (a). (c) TEM images of various nanocatalyst-on-SHIN structures. The insets in c are the zoomed-in image of the edge of the same particle as in main image. Scale bars, 20 nm. Scale bars for the insets, 5 nm.
