We present a detailed analysis of the electronic and geometric bonding properties of the model alkene ethene on different mono- and bimetallic surfaces to establish the difference between adsorption energy and interaction energy and to elucidate the chemical character of a single platinum atom in different chemical environments. The adsorption of ethene on Pt(111) at 100K leads to two adsorption states,...
The adsorption of ethene (C 2 H 4 ) on Pt(111) and the Pt 3 Sn/Pt(111) and Pt 2 Sn/Pt(111) surface alloys has been investigated experimentally by high-resolution electron energy loss spectroscopy and temperature programmed desorption. The experimental results have been compared with density functional theory (DFT) calculations allowing us to perform a complete assignment...
