Photodecomposition of 1,1,2-trichloroethane: spectroscopic evidence for vinyl formation on Pt(111)
High-resolution electron energy loss spectroscopy (HREELS) and temperature programmed desorption (TPD) were applied to the study of 1,1,2-trichloroethane adsorbed on Pt(111) and its reaction products. Adsorption at 85 K occurred molecularly, as verified by HREELS and TDS measurements. Upon heating,...

| description | High-resolution electron energy loss spectroscopy (HREELS) and temperature programmed desorption (TPD) were applied to the study of 1,1,2-trichloroethane adsorbed on Pt(111) and its reaction products. Adsorption at 85 K occurred molecularly, as verified by HREELS and TDS measurements. Upon heating, the molecule desorbed intact. Irradiation of the sample with a mercury arc lamp resulted in cleavage of the carbon-chlorine bonds and the formation of a new surface moiety: vinyl. HREELS measurements of both the deuterated and non-deuterated species confirmed this. Vinyl is stable until 450 K. After flashing to higher temperatures a new surface species was formed: chlorocarbyne. This species was no longer observed by 600 K. Throughout the entire heating procedure there was no evidence for the formation of ethylidyne. |
