Abstract

Continuous UV (λ ≥ 250 nm) irradiation of monolayer methyl halides adsorbed on Pt(111) leads to carbon-halogen bond cleavage. Contrary to what is found for gas phase and liquid phase photolysis, adsorbed methyl iodide is significantly more difficult to dissociate than methyl bromide. In coadsorption experiments, methyl bromide can be photolyzed without dissociating methyl chloride. Evidence for these processes is provided by post-irradiation analysis of products retained on the surface using vibrational, photoelectron, and thermal desorption spectroscopies.
