Abstract:
Adsorption and decomposition of ethylene as well as deposition of graphite on the (110) plane of platinum in the temperature range from 300 to 1450 K are studied by XPS, LEED, and TPR. It is shown that the process of ethylene decomposition proceeds through a number of intermediate species up to elementary carbon. At a temperature higher than 470 K there is penetration of the carbon into subsurface layers of platinum. This process is accompanied by the formation of a carbide-like phase of sandwich structure (CLPSS) stable at T⩽700 K responsible for modifying the surface properties. It is found that the mechanism of low-temperature graphite formation on Pt(110) is determined mainly by the decomposition of the CLPSS at T>700 K. The role of different parameters influencing the efficiency of the graphitization is discussed.
