A novel Ag2O/TiO2-modified chitosan-based photocatalytic film with high adsorption and photocatalytic activity was synthesized under simulated solar irradiation, based upon the coupling of the synergistic catalytic technique of nano Ag2O/TiO2 and membrane separation. XRD, XPS, FESEM, and TEM characterization results illustrated that the Ag2O nanoparticles with a small size of 3–5 nm deposited o...

Halloysite/Ag2O (Hal/Ag2O) nanomaterials were prepared by growing Ag2O nanoparticles on the surface of nanotubular halloysite using silver nitrate solution under alkaline conditions. The characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), and N2 adsorption. Good dispersion with average sizes 6.07 ± 2.5 nm 8.04 3.8 was achieved in when different concentrations alkali. ...

The structures of xAgI+(1−x)Ag2O⋅2B2O3 glasses, where 0.2<~x<~0.6, have been investigated using midand far-infrared spectroscopy. The mid-IR spectra revealed that in those glasses prepared using AgNO3 as the starting material for Ag2O, the BO−4/BO3 ratio is constant with increasing amounts of AgI as would be expected form the proposed behavior of AgI in these glasses. However, a survey of the l...

The magnetic and recyclable nanoparticles of CoFe2O4 were synthesized by a reverse co-precipitation process. Sonication was used to couple the CoFe2O4 surface with Ag2O. The characteristics and optical properties of the catalyst were studied by powder X-ray diffraction, UV–visible reflectance spectroscopy and scanning electron microscopy analyses. Pure CoFe2O4 and CoFe2O4/Ag2O were utilized to ...

The removal of water pollutants by photocatalysis is a promising technique, mainly due to its environmentally friendly and sustainable nature.

In the present study, the use of silver oxide nanoparticles (Ag2O NPs) synthesized using Ficus benghalensis prop root extract (FBPRE) as a reducing and stabilizing agent is reported and evaluated for its antibacterial activity against dental bacterial strains. The effects of pH, extract concentration, metal ion concentration, and contact time were studied to confirm the optimum production of Ag...

An electric field built inside a crystal was proposed to enhance photoinduced carrier separation for improving photocatalytic property of semiconductor photocatalysts. However, a static built-in electric field can easily be saturated by the free carriers due to electrostatic screening, and the enhancement of photocatalysis, thus, is halted. To overcome this problem, here, we propose sonophotoca...
