Oxygen Sensing of Pt/PEO-TiO2 in Humid Atmospheres at Moderate Temperatures
Sensors, 2021 Here, we show that the presence of adsorbed water improves the oxygen-sensing properties of Pt/TiO2 at moderate temperatures. The studied interface is based on porous plasma electrolytic oxidized titanium (PEO-TiO2) covered with platinum clusters.

Enhanced reactivity of adsorbed oxygen on Pd(111) induced by compression of the oxygen layer [PDF]
Physical Review B, 2005 The reaction between O atoms and CO molecules on Pd(111) was investigated by scanning tunneling microscopy (STM). CO was dosed on the $(2\ifmmode\times\else\texttimes\fi{}2)\mathrm{O}$-covered surface at temperatures between 100 and $190\phantom{\rule{0.3em}{0ex}}\mathrm{K}$, and the structure changes were monitored by STM.
