NSLS-II Colloquium Series

"Operando Spectroscopy of a Catalytic Solid: Towards a Molecular Movie"

Presented by Bert Weckhuysen, Utrecht University Netherlands, Netherlands

Wednesday, November 30, 2016, 4:00 pm — Large Seminar Room, Bldg. 510

The search for new or more effective catalysts would benefit from a multiscale science approach bridging the molecular world with the macroscopic world. Such detailed information can be realized if we would have access to a very powerful camera shooting molecular movies of a catalytic solid at work. This is the field of operando spectroscopy and recent breakthroughs in chemical imaging techniques, based on optical, electron and X-ray methods, demonstrate that such molecular movie concept is within reach. This lecture discusses the recent advances in spectroscopy and microscopy of catalytic solids at different length scales, starting from single molecules and single atoms up to the level of individual catalyst particles and ensemble effects in a reactor bed. Special emphasis will be devoted to the exploration of mesoscale effects in catalytic solids.
