Our primary thrust is the study of chemisorption and catalytic reactions on atomically clean and chemically modified surfaces using the full complement of modern surface science techniques. The materials being investigated include metal single crystals, oxide thin films, and metal clusters supported on thin oxide films.
Of concern are issues that are keys to understanding the relationship between surface structure and catalytic activity/selectivity. Surface techniques being used include Auger (AES), ion scattering spectroscopy (ISS), UV and X-ray photoemission spectroscopy (UPS and XPS), temperature programmed desorption (TPD), high resolution electron energy loss spectroscopy (HREELS), fourier transform infrared spectroscopy (IRAS), low energy electron diffraction (LEED), and scanning probe microscopies (STM and AFM). Current research includes: (1) the synthesis, characterization and surface chemistry of single crystalline oxide thin films; and (2) the simulation of supported metal catalysts using metal clusters deposited onto metal oxide surfaces.
Other ongoing work involves the study of the fundamental chemistry of processes that occur at the solid-gas and solid-liquid interfaces relevant to electrocatalysis, corrosion and the synthesis of refractory thin films for microelectronic applications.
