Heterogeneous photocatalysis has been considered one of the most effective and efficient techniques to remove organic contaminants from wastewater. The present work was designed examine photocatalytic performance metal (Cu Ni) doped ZnO nanocomposites in methyl orange (MO) dye degradation under UV light illumination. wurtzite hexagonal structure observed for both undoped/doped a crystalline siz...

Tobacco mosaic virus (TMV) has been employed as a robust functional template for the fabrication of a TMV/zinc oxide field effect transistor (FET). A microwave based approach, under mild conditions was employed to synthesize stable zinc oxide (ZnO) nanoparticles, employing a molecular precursor. Insightful studies of the decomposition of the precursor were done using NMR spectroscopy and materi...

A novel sensitive and selective ZnO/Co 3 O 4 /rGO nanocomposite was fabricated using a hydrothermal method used as non-enzymatic electrochemical sensor for the detection of glucose.

In recent years, the research of zinc oxide nanocomposites has attracted much attention. Due to high probability photonized carrier recombination a single nanometer material, and low utilization sunlight, its application in degradation pollutants is limited. Compounding with other materials can solve this problem. paper, through study photocatalytic properties nanocomposites, synthesis methods ...

Improving the performance of photoactive solid-state devices begins with systematic studies of the metal-semiconductor nanocomposites (NCs) upon which such devices are based. Here, we report the photo-dependent excitonic mechanism and the charge migration kinetics in a colloidal ZnO-Au NC system. By using a picosecond-resolved Förster resonance energy transfer (FRET) technique, we have demonstr...

The incorporation of nanostructured photocatalysts in polymers is a strategic way to obtain novel water purification systems. This approach takes the advantages of: (1) the presence of nanostructured photocatalyst; (2) the flexibility of polymer; (3) the immobilization of photocatalyst, that avoids the recovery of the nanoparticles after the water treatment. Here we present ZnO-polymer nanocomp...

in this study, tio2 and zno nanofilms were prepared by sol-gel spin-coating method. nanofilms were characterized by x-ray diffraction (xrd), energy dispersive analysis of      x-ray (edx), scanning electron microscopy (sem) and field emission scanning electron microscopy (fe-esm). structural and morphological properties of nanofilms were investigated. the average crystalline size of tio2 and zn...
