CFN Research Activities

We have applied the advanced scanning transmission electron microscopy and spectroscopy techniques to characterize catalysts, oxide thin film, materials for super-capacitors and electrode materials for Li-ion battery. In addition to the structural information, we are able to achieve the chemical information (composition, valence state, etc.) at sub-nano scale. Our results are essential to understand the relationship between structure/local chemistry and the property/activity in different systems, and help to improve the performance of catalysts/devices for energy convert/storage applications.
