【 摘 要 】

The adsorption and reaction of aniline on Cu(110) was studied using a combination of high resolution electron energy loss spectroscopy (HREELS) and temperature programmed desorption (TPD). HREEL spectra with an energy resolution of similar to 13 cm(-1) were obtained for both multilayer and monolayer aniline-derived surface species permitting a comprehensive comparison with the infrared spectra of liquid and gaseous aniline. The experimental results indicate that aniline forms randomly-oriented multilayers upon adsorption at 100 K, while at 300 K aniline adsorbs dissociatively forming stable C6H5NH surface species. This species decomposes between 525 and 875 K producing gaseous H-2 and N-2 and adsorbed carbon.
