Figure 3

Transmission electron microscopy (TEM) images of ruthenium (Ru)-decorated vertical graphene nanosheets (VGNS)@Ni foam: (a) low magnification bright field TEM image; (b) corresponding low magnification dark field TEM image, with the inset showing the corresponding selected area electron diffraction (SAED) pattern; (c–e) high magnification TEM images; (f) lattice-resolved TEM image. Inset of (c) is the Ru nanocrystal size distribution.
