Electron-Induced Decomposition of Metal Carbonyls on Ag(111). (Reannouncementwith New Availability Information)

摘要

The adsorption of Fe(CO)5 and Ni(CO)4 on Ag(111) at 90 K proceeds molecularlywith minimal decomposition, with both molecules desorbing in the temperature range 150-190 K. Bombardment of the adsorbed molecules with low energy electrons induces fragmentation and the formation of adsorbed MX(CO)y clusters. The Cluster
