2002 NSLS Users' Meeting

Recent Advances in the Application of Synchrotron Radiation to Catalysis

National Synchrotron Light Source, Bldg. 725B, Seminar Room

Wednesday, May 22, 2002

Organizer: Simon Bare, UOP, 847-391-3171

Research performed using synchrotron radiation has proven itself over the last 30 years to be of clear value to understanding the structure-function relationships of heterogeneous catalysts. The power of techniques such as x-ray absorption spectroscopy to probe the structure of adsorbed species under high vacuum conditions on model single crystal catalysts to solving the determining the structure of highly dispersed bimetallic clusters will be highlighted in this workshop.

This workshop will thus be of interest to researchers in all areas of catalysis. A varied program has been assembled, covering a variety of synchrotron radiation-based techniques that are used to study heterogeneous catalysts, with a focus on x-ray absorption spectroscopy and in situ studies. The speakers at this workshop are from academic, industrial and national laboratories.

In a follow-up to last year’s catalysis workshop part of this year’s workshop will report progress made on ways that the NSLS can attract more beamline users from the catalysis committee. Representatives from the NSLS and government agencies have been invited to provide perspective on this initiative.
