Living on the edge : Three‐dimensional reconstructions from electron tomography data recorded from Au/Ce 0.50 Tb 0.12 Zr 0.38 O 2−x catalysts show that gold nanoparticles (see picture; yellow) are preferentially located on stepped facets and nanocrystal boundaries. An epitaxial relationship between the metal and support plays a key role in the structural stabilization of the gold nanoparticles.
