The adsorption and desorption of oxygen on the Pt(110) surface; A thermal desorption and LEED/AES study

Surface chemistry of NO and NO2 on the Pt(110)-(1×2) surface: A comparative study

“…For NO 2 exposures below 0.5 L, no obvious oxygen desorption is observed from NO 2 /Pt(1 1 0), attributed to the dissolution of small amounts of oxygen resulted from NO 2 decomposition into the Pt (1 1 0) bulk. The oxygen desorption peak appears and grows with the NO 2 exposure increasing beyond 0.5 L, whose characteristics is similar to the combinative desorption peak of the surface oxygen from Pt(1 1 0)-(1 · 2) [16,36].…”

The formation of subsurface oxygen on Pt{110} (1×2) from molecular-beam-generated O2 Δg1

“…10, 11͒ and O 2 . 12,13 The surface temperature was monitored using a K-type thermocouple and controlled by a Eurotherm 904P programmable temperature controller. During TPD experiments, the sample was heated at a constant rate of 3 K s Ϫ1 .…”

A quantitative analysis of transient kinetic experiments: The oxidation of CO by O2 over Pt

“…2. Desorption of oxygen adatoms occurred at temperatures above approximately 480 K, which is much lower than the value of 650 K observed by Wilf and Dawson [22] for Pt(l 1 0). As already shown by Engel and Ertl [3] CO adsorption is possible on oxygen precovered surfaces.…”
