Abstract

The formation of carbonaceous deposits on Pt(110) surface due to ethylene decomposition in the temperature range of 770–970 K has been studied. Both kinetic and XPS data show that chemisorbed carbon (with no C−C bonds, but only C−Pt bonds) forms at T=770–870 K, the saturation coverage θs being about 1 ML. At higher temperatures, θs increases by a factor of 1.5, indicating the formation of more densely packed carbon species (DPC) due to C−C bonding. A kinetic model has been proposed to describe the process of carbon conversion.
