New forms of vanadium oxide Nanoporous were fabricated using a simple chemical synthesis method. Vanadium pentoxide (V2O5) Nanoporous were synthesized by sodium metavanadate as precursor and ethylene glycol as surfactant. The samples were characterized by high resolution transmission electron microscopy (HRTEM), field effect scanning electron microscopy (FESEM) and X-ray diffraction (XRD), Four...

The In-doped vanadium pentoxide nanostructures with different doping levels including 0, 10, 20 and 30 at.% were prepared by the spray pyrolysis technique. The prepared thin films were characterized by the x-ray diffraction (XRD) and scanning electron microscopy (SEM). The XRD results revealed that the films were crystalline in tetragonal phase. Increasing the In-doping level made the structure...

In this work, we present the role of vanadium ions (V+5 and V+3), oxygen vacancies (VO), and interstitial zinc (Zni) to the contribution of specific magnetization for a mixture of ZnO-V2O5 nanoparticles (NPs). Samples were obtained by mechanical milling of dry powders and ethanol-assisted milling for 1 h with a fixed atomic ratio V/Zn?=?5% at. For comparison, pure ZnO samples were also prepared...

In this study, we fabricated TiO2 nanorod arrays (TiO2), which were decorated with AgVO3 quantum dots (QDs) on and a layer of V2O5 film, forming heterojunction material for removal pollutants photoelectrochemical (PEC) water splitting. The AgVO3/V2O5-TiO2 (AgVO3/V2O5-TiO2) synthesized by the secondary hydrothermal method grown conductive glass to form one-dimensional (1D) p-n junction structure...

The recent intensive research for cathode materials beyond Li-ion batteries has revitalized interest in V2O5 due to its high reversible capacity. Among the various polymorphs, ??-V2O5 exhibits a unique corrugated layered structure that promotes insertion of guest species. However, when used as material SIB, this suffers from 50% first charge efficiency prevents full benefit discharge capacity 1...

This article discusses a simple vacuum evaporation technique for deposition of CdTe thin films with different thicknesses (100, 200, 300, 400, and 500) nm on P-type silicon substrates. Then, V2O5 SnO2 were deposited as buffer layer window thickness 100 respectively, using the same technique. In addition, other samples these have been glass substrate purpose studying optical transmission their p...
