The objective of the proposed research is to develop new ways to control the catalytic and selective oxidation of methane to oxygenates other then CO{sub 2} under mild reaction conditions by using halogen-free surface species that are stable under reaction conditions and that control the size of palladium ensembles available chemisorption of methane and oxygen. This will ensure the absence of Cl-containing products in the product and will result in surface modifiers, e.g. palladium alloy moieties, that are more stable at higher temperatures than are CCl{sub 2}- and Cl-produced site blocking agents. The model catalysts being utilized are initially single crystals of planar Pd(100), stepped Pd(311), and stepped and kinked Pd(679), which will also provide for the structure sensitivity of the selective oxidation of CH{sub 4} to be probed. 6 refs., 1 fig.
