ynchrotron radiation source is an accelerator-based light source with extremely high brightness and some very unique properties. It enables the researches and applications which are not possible in the regular laboratories. The X-ray spectroscopy techniques available at the synchrotron facilities provide a set of powerful tools for catalysis analysis. This presentation will give an overview of these techniques. As an example of research facilities, Canadian Light Source will be introduced briefly. A few detailed research examples will be presented to show the application in catalysis analysis.
