The photochemistry of phosgene (Cl{sub 2}CO) on clean and partially iodine covered Ag(111) has been studied. Cl{sub 2}CO adsorbed on Ag(111) at 100 K desorbs molecularly with no detectable thermal decomposition. On clean Ag(111) K, UV photolysis occurs readily for both submonolayer and multilayer coverages. The photolysis products are chlorine, which remains on the surface, and CO, which desorbs during irradiation. There is no detectable photodesorption of molecular Cl{sub 2}CO.
