Development and Application of in-Situ and Operando Transmission Electron Microscopy for Photocatalysis

Significance:

This is the first light illumination system attached to the ETEM which preserves the capability of in-situ thermal processing of catalysts. Atomic level structure-property relationships of both the semiconducting oxides and the co-catalyst and their relations to activation and de-activation are explored under in-situ and operando conditions.
