Fundamental Aspects of Photocatalysis Enlighted by In-Situ Electron Microscopy

Description

This contribution aims to highlight the potential of electron microscopy for progressing in designing efficient photocatalysts by creating a fundamental understanding of the critical process steps. State-of-the-art transmission electron microscopes will be presented, enabling to follow the life cycle of a photocatalyst from its synthesis to its final application. The premise for systematically studying structure-property relationships includes the controlled synthesis of nanostructures. Therefore, this contribution will shed light on the capabilities of environmental transmission electron microscopes with integrated chemical vapor deposition systems to study and control the evolution of phases and interfaces in multicomponent nanoparticles. Subsequently, in-situ electron microscopy investigations of photocatalysts under realistic application conditions, including light irradiation, will be presented.
Finally, an outlook highlighting the possibilities of next-generation electron microscopes focusing on 4D scanning transmission electron microscopy techniques will be presented. The advancing development of electron microscopes in spatial resolution, imaging/spectroscopy techniques, and setups enabling experiments under environmental conditions can potentially create deep insights into fundamental aspects of photocatalytic reactions. Progress in this field will require the interplay between different research fields to tackle the involved challenges, design meaningful experiments, and understand the generated data.
