Looking good: High-resolution TEM can be used to determine the surface structure of a metal oxide catalyst in real space. The picture shows HR-TEM images of one catalyst particle along 〈001〉 direction far from Scherzer focus. The perimeter of the particle is highlighted by the fractured structural units.
