Relative Stability of Near-Surface Oxygen Vacancies at the CeO2(111) Surface upon Zirconium Doping
(American Chemical Society, 2019-12)
The effects of Zr doping on the stability of the CeO2(111) surface as a function of the dopant concentration and distribution, as well as on the relative stability of surface and subsurface oxygen vacancies, were studied ...
Oxygen related defects excitation and photoconductivity dependence of SnO2 sol-gel films with several light sources
(1999-12-01)
Since oxygen vacancies act as donors in SnO2, the electrical properties are related to deviation from stoichiometric composition. Depending on stoichiometry SnO2 can be highly insulating or may exhibit fairly high n-type ...

Coupling of Acetaldehyde to Crotonaldehyde on CeO 2-x (111): Bifunctional Mechanism and Role of Oxygen Vacancies
(American Chemical Society, 2019-04)
Selective C-C coupling of oxygenates is pertinent to the manufacture of fuel and chemical products from biomass and from derivatives of C 1 compounds (i.e., oxygenates produced from methane and CO 2 ). Here we report a ...
Oxygen vacancies and peroxo groups on regular and low-coordinated sites of MgO, CaO, SrO, and BaO surfaces
(Elsevier Science, 2006-03)
The formation of an oxygen vacancy and the simultaneous re-adsorption of an oxygen atom on regular and low-coordinated (LC) sites (edges and corners) of the surface of alkaline-earth oxides with cubic rock salt structure, ...
Low-frequency ultrasound induces oxygen vacancies formation and visible light absorption in TiO 2 P-25 nanoparticles
(Elsevier, 2012-05)
Low-frequency ultrasound (LFUS) irradiation induces morphological, optical and surface changes in the commercial nano-TiO 2-based photocatalyst, Evonik-Degussa P-25. Low-temperature electron spin resonance (ESR) measurements ...
