Oxygen vacancies(Ov)engineering has demonstrated tremendous power to expedite electrocatalytic kinetics for oxygen evolution reaction(OER).The mechanism is elusive,and most of them were attributed to the decoration or creation of active sites.Here,we report the critical role of superfcial Ov in enh...
oxygen vacancies has a positive effect on enhancing photocatalytic activity[56]. For example, the surface oxygen vacancies can shorten the band gap by forming defective states below the conduction band, expanding the range of light absorption, and can also act as electron capture centers to inhibit...
The amount of oxygen desorbed increased with increasing Sr content at a fixed B-site composition, for which an increase in the number of oxide ion vacancies with x was responsible. On the other hand, the total amount of oxygen desorbed was hardly affected by B-site composition, but partial...

Treasure OVE: The performance of doped ceria for CO2 adsorption is investigated by oxygen vacancy engineering (OVE), that is, the formation and regeneration of oxygen vacancies. The doping and synthesis methods can be adapted to OVE, while reduction with hydrogen effectively restores the number of...

the introduction of defects, such as oxygen vacancies (OVs) mainly. [8,9] OVs are the most prevalent and widely-studied anion defects with a relatively lower formation energy on oxide surfaces. The OVs-induced localized states could extend light response to visible/IR light and efficiently...
The oxygen deficiency penetrates into the bulk of individual primary particles (~200 nm) and is well-described by oxygen vacancy diffusion. Using an array of characterization techniques, we demonstrate that, surprisingly, bulk oxygen vacancies that persist within the native layered phase are indeed...
