Paper Abstract

Alkyl radicals play a key role as reaction intermediates for many surface processes such as catalytic hydrocarbon synthesis or the degradation of coatings and lubricants. Their properties and reactivity on surfaces, however, are still poorly understood because simple synthetic routes to prepare them have not yet been developed and their identification among other hydrocarbon fragments requires highly specific and sensitive techniques. Using alkyl halides as precursors, we have prepared alkyl species on single crystal surfaces in an ultrahigh vacuum (UHV) environment and studied their surface chemistry by a combination of different surface science techniques. In this report we present an IR spectroscopic study on the formation of ethyl species from ethyl iodide and their decomposition on a Pt(111) surface.
