An Electron Spectroscopic Investigation of the Interaction of Methanol with Polycrystalline Aluminum

Abstract

X-ray and ultraviolet photoelectron spectroscopic results are reported for the interaction of CH3OH with clean polycrystalline Al in the temperature range 110-500 K. Methanol is molecularly chemisorbed at low exposure and low temperature (110 K) followed by condensation at higher exposure. The multilayers desorb beginning near 170 K and the chemisorbed layer is converted into a surface methoxide. Room temperature adsorption also leads to formation of the methoxide species which is stable to approximately 500 K, at which point it decomposes evolving CH4 and leaves the surface oxidized.
