Oxygen vacancies and adsorbed oxygen species on metal oxide surfaces play important roles in various fields. However, existing methods for manipulating surface oxygen require severe settings and are ineffective for repetitive manipulation.

Oxygen reduction on adsorbed iron tetrapyridinoporphyrazine
Materials Chemistry and Physics, 1989Abstract The electrocatalytic properties of iron tetrapyridino porphyrazine FeTPyPz for the reduction on O2 in alkaline media have been examined with cyclic voltammetry and rotating ring disk techniques. Four distinct redox peaks are observed in the absence of O2 in solution for this material adsorbed at monolayer coverages on ordinary pyrolytic ...

The structure-performance relationship of α-, β-, γ- and δ-MnO2 catalysts were studied. The four samples exhibited different activities of toluene oxidation in terms of distinct tunnel sizes, surface-active oxygen and redox properties.

Adsorbed Oxygen as an Amorphous Antiferromagnetic System
Physical Review Letters, 1977Oxygen adsorbed on porous Vycor glass, a heterogeneous substrate, displays properties of an amorphous antiferromagnet. However, no antiferromagnetic ordering transition is seen for submonolayer coverages in the temperature range studied (1.9--95 K) although these coverages have paramagnetic Curie temperatures as large as -50 K.

Thermal rearrangement of oxygen adsorbed on oxygen-rich Ru(0001)
Surface Science, 2001Abstract Atomic oxygen adsorbed on oxide domains terminating an oxidized Ru(0 0 0 1) surface is marked by its unusually high chemical reactivity as compared to other known oxygen species. We applied thermal desorption spectroscopy employing isotopic labeling to characterize the thermally driven incorporation of these oxygen atoms into the subsurface ...

Roles of Oxygen Vacancies in the Bulk and Surface of CeO2 for Toluene Catalytic Combustion.
Environmental Science and Technology, 2020Catalytic combustion technology is one of the effective methods to remove VOCs such as toluene from industrial emissions. The decomposition of aromatic ring via catalyst oxygen vacancies is usually the rate-determining step of toluene oxidation into CO2.

Oxygen on Cu(100) – a case of an adsorbate induced reconstruction
Surface Science, 1989Abstract We show that at and above room temperature only a single long range ordered superstructure exists on Cu(100). This is the ( 2 × 2 2 )R45° structure, which corresponds to a saturation coverage of θo = 0.48 ± 0.05. A well-ordered c(2 × 2) superstructure is not observed in the investigated range of adsorption temperatures (Tads = 300–

Journal of Hazardous Materials
Here, a quenching strategy was developed to create oxygen vacancies in Cu doped α-MnO2. The evolutions of oxygen vacancies were directly followed by means of XRD refinement, EPR and XPS. In combination with DFT calculations and detailed characterizations,

Adsorbents in Liquid Oxygen Containers
1960The liquid oxygen converter has become an important component in modern military aircraft. As a result high vacuum containers for liquid oxygen must be made which meet increasing demands of reliability under increasingly adverse conditions. The success of the containers depends upon maintaining a high static vacuum for as long a period as possible.
