Oxygen Vacancy In subject area: Engineering Generally speaking, oxygen vacancy (OVs) refers to the vacancy formed by the separation of oxygen atoms (oxygen ions) in the lattice in metal oxides or other compounds containing oxygen. From: Fuel, 2024 About this pageSet alert Also in subject areas...
The presence of several oxygen vacancies (VO) is of great importance for nanocomposites to be used in nanomaterials.1,2,3The electronic structure and catalytic properties of metal oxides (MO) can be tuned by introducing defect sites such as a vacancy and heteroatom, which manipulate their donor ...
Oxygen vacancy (OV) is native defects in transition metal (TM) oxides and their presence has a critical effect on the physicochemical properties of the oxide. Metal oxides are commonly used in lithium﹊on battery (LIB) cathodes and there is still a lack of understanding of the role of OVs ...
As one of the most common defects in metal oxides, oxygen vacancy could effectively regulate the electronic structure on the surface of catalysts, enhance electron enrichment and activate H2O molecules [15,16]. That is, cobalt-based catalysts may be the promising candidates for COS hydrolysis. ...

Finally, the current challenges and outlooks of Vo engineering are highlighted for future development of high‐performance layered oxide cathode materials. 展开 关键词: oxygen vacancy Li/Na-ion batteries cathodes layered transition-metal oxides structural modulation ...
Recent studies have identified conductive states at surfaces and interfaces of pure oxide materials; high electron concentrations are present, resulting in a high-mobility two-dimensional electron gas. We demonstrate for In2O3that the energy required to form an oxygen vacancy decreases rapidly towards...
