Electron microscopy: Shape of a crystal from one image

Real-space observation of strong metal-support interaction: state-of-the-art and what's the next

The real-space resolving of the encapsulated overlayer in the well-known model and industry catalysts, ascribed to the advent of dedicated transmission electron microscopy, enables us to probe novel nano/micro architecture chemistry for better application, revisiting our understanding of this key issue in heterogeneous catalysis. In this review, we summarize the latest progress of real-space observation of SMSI in several well-known systems mainly covered from the metal catalysts (mostly Pt) supported by the TiO2 , CeO2 and Fe3 O4 . As a comparison with the model catalyst Pt/Fe3 O4 , the industrial catalyst Cu/ZnO is also listed, followed with the suggested ongoing directions in the field.

Transmission electron microscopy finds plenty of room on the surface

The merit of transmission electron microscopy is unraveled for the key progress, emerging opportunities and fascinating perspectives in surface exploration.
