Abstract

Examines the 100 eV electron-induced decomposition of methanol adsorbed on the vacuum annealed surface of TiO2(110) with temperature programmed desoprtion and electron stimulated desorption. Results demonstrate the ability of low energy electrons to activate organics adosrbed on oxide surfaces with high cross sections and suggest that the EID cross sections and products for surface organics depend on the coverage, adsorption state and adsorption site. Concludes that low energy electrons produced from absorption of ionizing radiation may play a significant role in the radiocatalytic destruction of organics over oxide catalysts.
