Studies of Ethylene Oxide Adsorption on Pt−Sn Alloys with TPD, HREELS, UPS, and DFT Calculations

Ethylene oxide (EO) adsorption was studied on two ordered surface alloys: (2 × 2)-Sn/Pt(111) with θSn = 0.25 ML, and (√3 × √3)R30°-Sn/Pt(111) with θSn = 0.33 ML. Nearly all EO desorbs molecularly during TPD in peaks at 198 K for the (2 × 2) alloy and 190 K for the (√3 × √3)R30° alloy, corresponding...
