Reaction of O2 with Subsurface Oxygen Vacancies on TiO2 Anatase (101)
Martin Setvin, Ulrich Aschauer, Philipp Scheiber +5
Oxygen (O2) adsorbed on metal oxides is important in catalytic oxidation reactions, chemical sensing, and photocatalysis. Strong adsorption requires transfer of negative charge fro…

(Sub)surface mobility of oxygen vacancies at the TiO anatase (101) surface
Philipp Scheiber, Martin Fidler, Olga Dulub +5
Anatase is a metastable polymorph of TiO. In contrast to the more widely-studied TiO rutile, O vacancies (V's) are not stable at the anatase (101) surface. Low-…
