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...
It has been found that changing the local electronic structure by introducing dopants can regenerate oxygen vacancies. Chen et al. [82] prepared metal Bi to prevent the deactivation of oxygen vacancies in Bi2O2CO3 and improved the photocatalytic stability of oxygen vacancies. The combination of ...
The formation of oxygen vacancies is one of the most critical factors that can improve the electronic and catalytic properties of metal oxides, in which an important challenge is to lower the formation energy of oxygen vacancies at the interface structur
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...

we performed operando TEM in liquids to probe the dynamic wetting behaviour of oxygen-evolving cobalt-based oxide catalysts under potential cycling, including probing of the highly OER-active perovskite Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF), where δ denotes the number of oxygen vacancies. ...
