Thermal reactions of 2-iodoethanol on Cu(100)

[[abstract]]Temperature-programmed reaction/desorption, X-ray photoelectron spectroscopy, and reflection-absorption infrared spectroscopy have been employed to investigate the reactions of ICH2CH2OH on Cu(100) under ultrahigh-vacuum conditions. ICH2CH2OH can dissociate on Cu(100) at 100 K, forming a -CH2CH2OH surface intermediate. Density functional theory calculations predict that the -CH2CH2OH is most probably adsorbed on atop site. -CH2CH2OH on Cu(100) further decomposes to yield C2H4 below 270 K. No evidence shows the formation of -CH2CH2O- intermediate in the reactions of ICH2CH2OH on Cu(100) in contrast to the decomposition of BrCH2CH2OH on Cu(100) and ICH2CH2OH on Ag(111) and Ag(110), exhibiting the effects of carbon-halogen bonds and metal surfaces.[[fileno]]2010334010024[[department]]化學
