Abstract:

The interaction of methanol with Pd111 has been studied using high resolution electron energy loss spectroscopy HREELS. We find both a chemisorbed and a physisorbed phase on the surface at 140K. Desorption of the physisorbed phase occurs by 160K and approximately 90 of the chemisorbed layer desorbs by 300K. Exposure to methanol at 300K causes dissociation of chemisorbed CO. Decomposition of chemisorbed methanol to a methoxy species occurs near 200K in the presence of a preadsorbed p2x2 oxygen layer whereas no methoxy is detected on the clean surface.
