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 this study, the degradation recalcitrant organic pollutant, malachite green (MG), was investigated in microstructured silver oxide photocatalyst. (Ag2O) microparticles (MPs) were synthesized low-cost, method, mediated tea leaves extract. surface, morp...

In this research, tungsten oxide (WO3), silver (Ag2O), and Ag2O/WO3 nanocomposites were synthesised by precipitation sonication method, respectively. X-ray diffraction (XRD), Fourier Transform Infrared spectroscopy (FTIR), Scanning Electron Microscopy (SEM) UV-Visible used to confirm the structural, spectral, morphological, optical properties of as-synthesised samples, The as-prepared nanocompo...

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...

We report in this paper a facile approach for the formation and electrochemical characterization of silver-silver oxide core-shell nanoparticles (NPs). Thus, thermal treatment at temperatures between 200 and 360 degrees C of Ag NP, in the gas phase or in an organic solvent, has been used to achieve the formation Ag@Ag2O NP. The evidence of formation of such a core-shell structure was obtained b...

Potential of root system of plants from wide range of families to effectively reduce membrane impermeable ferricyanide to ferrocyanide and blue coloured 2,6-dichlorophenol indophenol (DCPIP) to colourless DCPIPH2 both under non-sterile and sterile conditions, revealed prevalence of immense reducing strength at root surface. As generation of silver nanoparticles (NPs) from Ag+ involves reduction...

Plasmon-enhanced light absorption in a multicomponent Ag/Ag2O/TiO2/N3 dye-sensitized solar cell (DSSC) core−shell nanostructure is studied using a hybrid quantum mechanics/classical electrodynamics (QM/ED) methodology in which the Ag/Ag2O/TiO2 nanostructure is treated by the finite-difference time-domain method and the N3 dye is treated by real-time time-dependent density functional theory. As ...
