Nanocomposite of Ag/TiO2 and nanocrystalline TiO2 were prepared by using TiCl4 as a precursor in a simple sol-gel process. The prepared photo-catalysts were characterized by X-ray diffraction (XRD), scanning electron micrographs (SEM), energy dispersive X-ray microanalysis (EDX), transmission electron microscopy (TEM) and diffuse reflectance spectroscopy (DRS). A complete and effective photocat...

We report an environmentally friendly synthetic strategy to fabricate reduced graphene oxide (rGO)-based ternary nanocomposites, in which glutathione (GSH) acts both as a reducing agent for graphene oxide and sulfur donor for CdS synthesis under modified hydrothermal (MHT) conditions. The report becomes interesting as pH variation evolves two distinctly different semiconducting nanocrystals of ...

Engineering hierarchical structures of electrode materials is a powerful strategy for optimizing the electrochemical performance of an anode material for lithium-ion batteries (LIBs). Herein, we report the fabrication of hierarchical TiO2/C nanocomposite monoliths by mediated mineralization and carbonization using bacterial cellulose (BC) as a scaffolding template as well as a carbon source. Ti...

TiO2 photocatalysts have been found to kill cancer cells, bacteria and viruses under mild UV illumination, which offers numerous potential applications. On the other hand, Ag has long been proved as a good antibacterial material as well. The advantage of Ag-TiO2 nanocomposite is to expand the nanomaterial's antibacterial function to a broader range of working conditions. In this study neat TiO2...

NanoTiO2 , nanoZrO2 and TiO2 /ZrO2 nanocomposite were prepared via sol gel method by using ultrasonic irradiation. The precursor sol of zirconium was prepared from an aqueous solution of ZrCl4 and titanium tetra 2-propoxide was diluted by 2-propanol and deionized water The TiO2 /ZrO2 nanocomposite was synthesized from directly mixing Titanium dried gel into Zirconium gel. The reaction mixture w...

In the present study, a nanocrystalline Ni-Fe matrix with reinforced TiO2 nanoparticles as functional nanocomposite material was fabricated by pulsed current electroforming in UV-LIGA (lithography, electroplating, and molding). The influences of on deposition were also investigated using scanning electron microscopy, transmission vitro cytotoxicity assay. It found that 5 wt.% showed smooth surf...

Abstarct: Nanostructured colloidal semiconductors with heterogeneous photocatalytic behavior have drawn considerable attention over the past few years. This is due to their large surface area, high redox potential of the photogenerated charge carriers, and selective reduction/oxidation of different classes of organic compounds. In the present paper, we have carried out a systematic synthesis of...

Novel ternary nanocomposite photocatalysts based on g-C3N4/Fe3O4/TiO2 nanosheet were synthesized using simple solid combustion, hydrothermal and wetness impregnation methods. The g-C3N4 nanosheet (2D)/ Fe3O4/ TiO2 nanosheet (2D) triad-interface nanocomposite arranged in the form of Fe3O4 nanoparticle was sandwiched and well dispersed on the surface between g-C3N4 and TiO2 nanosheets. The synthe...
