Generally, oxygen vacancy defect is a loss of oxygen atom from their respective position in the crystal lattice and mainly exist both in the bulk and on the surface or subsurface of the nanomaterials. From: Nanostructured Materials for Visible Light Photocatalysis, 2022 ...
: oxygen dopant, nitrogen defect, g-C3N4, photocatalysis, hydrogen productionGenerally, bulk graphic carbon nitride (g-C 3 N 4 ) suffers from fast photogenerated charge carrier combination, inferior adsorption of visible light and low specific areas. Herein, we develop a defect engineering to ...
Oxygen vacancies (Vo) in metal oxides bring many benefits for photocatalysis like creating visible light adsorption by generating isolated level below the conduction band and improving the donor density and electrical conductivity by providing shallow donors [17], [18], [19], [20], [21], [22]...

This is moti- vated by our recent demonstration that specific capacitance of TiO2 nanostructures are significantly improved by increased donor densities resulted from introduction of oxygen vacancy states via thermal treatment in hydrogen atmosphere20. For the design of high- performance photovoltaic ...
can the vacancy-induced defect dipoles be rationally tuned to facilitate the CST process in photoelectrodes remains unanswered. In addition to the CST engineering in the PEC system, the optimization of surface reaction for utilizing the photogenerated charge carriers is equally important to achieve ...
