Figure 2

Orthogonal slices are taken from the 3D HAADF STEM reconstructions of an isolated γ-Alumina/Pt particle. (a) A representative section parallel to the broad surface of γ-Alumina, axial slice parallel to XY- plane, (b,c) are axial slices parallel to YZ and XZ-planes, respectively. The large particle with dimmer contrast is γ-Alumina, marked with a gray arrow. Smaller round particles with brighter contrast are Pt NPs, and a few examples are marked with white arrows. Pores are marked with yellow arrows.
