The control of surface reactivity has major economic implications in heterogeneous catalysis. For the chemical tuning of catalytic metal centers, redox-active, on-surface coordination to a diverse repertoire of ligands is of great interest for the self-assembly of ordered supramolecluar networks and control of the metal oxidation state. It is necessary to extend strategies for surface coordination from model systems towards those of a practical interest. We are working to study applications of C-H bond activation resulting from the interaction of small alkanes and oxygen with single-site catalysts under ultra-high vacuum conditions. Our experiments utilize several complementary analysis methods, including a pulsed supersonic molecular beam, X-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), high-resolution electron energy loss spectroscopy (HREELS), low-energy electron diffraction (LEED), temperature programmed desorption (TPD), and scanning tunneling and atomic force microscopy (STM/AFM). New measurements into surface structure and reactivity on metal supports and supported catalyst compounds will be presented.
