Mechanisms and controlling characteristics of the catalytic oxidation of methane
Progress has included (1) construction and installation of an ultraviolet photoelectron spectrometer (UPS) with power supply and pumping system that has been added as an attachment to the SCIENTA ESCA-300 instrument, (2) modification of the high resolution electron energy loss spectrometer (HREELS) to produce a stable ultra high vacuum (UHV) environment for initial experiments with a Pd(311) single crystal, (3) construction of a separate high vacuum system for preparation of surface doped model catalysts by chemical vapor deposition and pretreatment of a Pd(100) single crystal in this system, (4) carried out detailed experiments of methane activation and oxidation on Pd(679) using a high pressure reaction cell contained in a third ultra high vacuum system, (5) completion of adsorption/desorption studies of H{sub 2}, CO, and O{sub 2} on Pd(679), (6) utilized angle-resolved XPS to probe the diffraction characteristics and structure of the Pd(100) surface, (7) determination of the electronic surface structure of Pd(100) using angle-resolved UPS, and (8) computational analysis of oxygen overlayers on the PD(100) surface. Each of these is discussed in further detail below.
