Geoffroy, G L

The major aim of nearly all synthesis gas research involves the development of more active and selective catalysts. One way to approach catalyst development is through mechanistic studies whereby an understanding of the mechanistic course of the reaction should allow the design of more efficient catalysts. It is the major aim of this research program to contribute to that mechanistic understanding. Two approaches will be employed in this research. First, certain aspects of the mechanism of the heterogeneous metal surface catalyzed reduction of CO will be probed using transition metal cluster complexes to model the chemistry of metal surfaces. Secondly, we will address various aspects of the mechanism of homogeneous CO reduction by focusing on a few key mechanistic steps, particularly halide-promoted reactions and the formation, stabilization, and reactivity of formyl, acyl, methylene, and ketene ligands. Some exploratory work is also proposed involving studies of the adsorbed state of simple unsaturated molecules on metal surfaces using solid-state /sup 13/C NMR spectroscopy, as well as reactions which model non-synthesis gas chemistry of metal surfaces. 39 refs., 7 figs., 1 tab.
