UNLABELLED TeO2-nanostructured sensors are seldom reported compared to other metal oxide semiconductor materials such as ZnO, In2O3, TiO2, Ga2O3, etc. TeO2/CuO core-shell nanorods were fabricated by thermal evaporation of Te powder followed by sputter deposition of CuO. Scanning electron microscopy and X-ray diffraction showed that each nanorod consisted of a single crystal TeO2 core and a poly...

This paper presents the preparation and characterization of a porous antimicrobial composite material consisting diatomaceous earth, an inorganic pore-forming agent, nano-zinc oxide (ZnO). A modified direct precipitation device produced high-surface area ZnO powder. The effect reaction temperature, volume flow rate, titration rate on particle size was studied. Using sodium chloride, potassium n...

In this study, magnetically separable ZnO/CuFe2O4 nanorod particles were synthesized by the green synthesis approach, using rambutan peel extract (Nephelium lappaceum L.) as a capping agent. The samples evaluated photocatalyst for degradation of Rhodamine B dye driven solar light irradiation. XRD patterns represented specific peaks ZnO and CuFe2O4 in composite. SEM TEM images showed rod-like sh...

Possible ferro-electromagnetic performance of “reduced graphene oxide (r-GO)” deposited on the surface “ZnO-nanorod (NR) decorated with nanocrystalline (nc) Au particles” is studied using different spectroscopies and magnetic measurements. The presence carbon/zinc-interstitials (Zni), nc-Au, oxygen vacancies are established through electronic property studies spectroscopic moment (M) applied fi...

Dense and vertically aligned ZnO nanorod arrays with a large area have been fabricated successfully on the stainless steel mesh by a simple chemical vapor deposition method. The coated mesh exhibited both superoleophilic and superhydrophobic properties, even if it was not modified by low surface energy materials. The separation efficiencies were more than 97% in the filtration of water and oil....

Graphene oxide-zinc oxide hybrid nanostructures were synthesized and they demonstrated significant and promising antimicrobial activity on pathogenic bacteria. The combination of graphene oxide with zinc oxide nanorods showed an impressive antibacterial effect under intense scrutiny as compared with individual graphene oxide or zinc oxide nanomaterials. The characterization and investigation of...

Abstract In this work, we have investigated the structure, morphology, photoluminescence, photocatalytic and photocurrent properties of ZnO thin films as a function their film thickness (t ) fabricated via ultrasonic spray pyrolysis technique. The X-Ray diffraction patterns exhibited formation polycrystalline wurtzite phase ZnO. Scanning electron microscopy images showed uniform morphology with...
