Abstract:
The properties of carbon layer on the Pt(111) surface with submonolayer coverage and its activity towards hydrogen have been studied by low electron energy loss spectroscopy and thermal desorption mass spectrometry. The layer of C(ads) atoms was prepared from a special source which produced a carbon atom flow free of admixtures and clusters. It was shown that after deposition of carbon on Pt(111) at 100 K and with nC ≈ 2 × 1014 cm-2 the layer was obtained chiefly containing the isolated C(ads) atoms. The high activity of the adsorbed atoms was established; the reaction C(ads) + H(ads) was initiated at 170 K and in the course of reaction CH(ads) was produced. These particles are stable towards dissociation up to 500 K. Interaction of the carbon layer (nC ≈ 1015 cm-2 with hydrogen gives rise to the formation of more complex particles and, in particular, ethylidyne ({A figure is presented}(ads) identified according to the following vibrational bands: v(CC) at 1130 cm-1 and δs(CH3) at 1370 cm-1.
