The 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).
