he Chemistry Department's program in Catalysis - Reactivity and Structure, supported by the Division of Chemical Sciences of the Department of Energy investigates fundamental aspects of chemical catalysis from a multi-faceted perspective. BNL's National Synchrotron Light Source (NSLS) plays a key role in some of this research, often via collaborative efforts with scientists from other institutions.

Reactivity-structure correlations are at the heart of the group's efforts related to heterogeneous catalysis and surface science. Specific emphasis is placed on understanding the effects of catalyst promoters and poisons  at a molecular level and on understanding the distinctive catalytic behaviors of transition metal compound, oxide, carbide etc. surfaces that may serve as models for industrial catalysts. Catalytic reactions on surfaces are investigated by ultra-high vacuum surface science techniques, infrared spectroscopy, and high-pressure kinetics, while the structures of the active surfaces and adsorbates are probed by a variety of methods including x-ray and ultraviolet photoelectron spectroscopies at the NSLS's U7A beamline. In addition to these studies, novel in situ diffraction studies are being undertaken at the NSLS's X7B beamline in order to understand the formation and transformations of catalytic materials under both synthesis and catalytic reaction conditions (X7B).
