摘要：

The adsorption of ethene on the Pt3Cu(111) surface at 95 K has been studied by high-resolution electron energy loss spectroscopy (HREELS), temperature-programmed desorption (TPD), low-energy electron diffraction (LEED), and work-function change measurements. Both the TPD and HREELS measurements reveal the existence of two different ethene species on the surface. These species can be identified as a weakly bonded pi-complex and a stronger bonded di-sigma-complex. No ethene-induced superstructure has been found with LEED. The TPD experiments indicate that ethene is not dehydrogenated/decomposed when the surface is heated above the desorption temperature. (C) 1999 Elsevier Science B.V. All rights reserved.
