Insight into the Mechanism of Antibacterial Activity of ZnO: Surface Defects Mediated Reactive Oxygen Species Even in the Dark
TL;DR: It is conclusively proved that reactive oxygen species (ROS) such as (•)OH, ( •)O2(-), and H2O2 are significantly produced from aqueous suspension of ZnO even in thedark and are mainly responsible for the activity in the dark up to 17%, rather than Zn(2+) ion leaching as proposed earlier.
Journal ArticleDOI
A New Synergetic Nanocomposite for Dye Degradation in Dark and Light.
TL;DR: The synergically coupled nanocomposite of ZnO2/ppy is the first example that degrades dyes in the dark, through advanced oxidation process without employing additional reagents, so that the efficiency of dye removal is enhanced.
Journal ArticleDOI
Chemical manipulation of oxygen vacancy and antibacterial activity in ZnO.
TL;DR: For the first time, material design in terms of cation doping and anion doping to tune oxygen vacancies has been carried out and it was found that nano Na doped ZnO releases highest amount of ROS followed by nano ZNO, micron N dopedZnO while micron ZnNO releases the least amount ofros, illustrating directly the correlation between ROS and oxygen vacancy in well designed pure and doped znO.
Journal ArticleDOI
Simultaneous Fenton–Photocatalytic Reactions through a New Single Catalyst (Nano ZnO2 /Fe2+) for Dye Degradation
TL;DR: In this paper, a new Fenton-photocatalytic catalyst was proposed for environmental remediation, which works in the dark (Fenton-like), under visible light (photo-Fenton) and UV light (photocataloytic) mechanism.
Journal ArticleDOI
Metal peroxides as potential photocatalysts for environmental remediation
TL;DR: In this article , the photocatalytic activity of metal peroxides capable of generating reactive oxygen species (ROS) in aqueous solutions has been investigated for environmental remediation.
