metal oxides play a very important role in many areas of chemistry, physics and materials science.the metal elements are able to form a large diversity of oxide compounds. in this investigation, wesynthesis sno2 and c,n,s-tridoped sno2 nanoparticles by precipitation method. the synthesizedsno2 and c,n,s-tridoped sno2 nanoparticles were characterized by instrumental analysis methods,such as x-ra...

SnO2 nanosheet-structured films were prepared on a fluorine-doped tin oxide (FTO) substrate using ZnO nanosheet as template. The as-prepared SnO2 nanosheets contained plenty of nano-voids and were generally vertical to the substrate. TiO2 nanoparticles were homogeneously deposited into the intervals between the SnO2 nanosheets to prepare a hierarchically structured SnO2/TiO2 hybrid film. The hy...

An inexpensive single-step carbon-assisted thermal evaporation method for the growth of SnO2-core/ZnO-shell nanostructures is described, and the ethanol sensing properties are presented. The structure and phases of the grown nanostructures are investigated by field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) techniques. XRD a...

Article history: Received 25 May 2015 Received in revised form 20 June 2015 Accepted 21 June 2015 Available online xxxx Thin-film siliconmodules are commonly produced by an alternating sequence of layer deposition and layer patterning steps, which lead to amonolithic series connected device. Most used process is laser scribing process that offers a high throughput and a small area loss. Tin oxi...

We report gas-phase production of metal oxide nanowires (NWs) and nanoparticles (NPs) using direct oxidation of micron-size metal particles in a high-throughput, atmospheric pressure microwave plasma jet reactor. We demonstrate the concept with production of SnO2, ZnO, TiO2, and Al2O3 NWs. The results suggest that the NW production primarily depends upon the starting metal particle size, microw...

The paper reports the preparation and photocatalytic activity of ZnO/SnO2 and SnO2 nanoparticles. These nanoparticles were synthesized by hydrothermal method. The products were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Their grain sizes are about 50-100 nm. The photocatalytic activities of these materials were investigated for congo red removal from aqueou...

A series of SnO2-ZnO composite nanostructured (thin) films with different amounts of SnO2 (from 0 to 50 wt %) was prepared and deposited on a miniaturized porous alumina transducer using the sol-gel and dip coating method. The transducer, developed by our research group, contains Au interdigital electrodes on one side and a Pt heater on the other side. The sensing films were characterized using...

this paper reports the synthesis of polypyrrole coated sno2/znoelectrospunnanofibers via vapor phase polymerization method. in order to prepare one dimensional (sno2-zno)/polypyrrole with the core sheath structure, first sno2-zno composite nanofibers were synthesized via electrospinning method followed by adsorption of fe3+ on the surface of the sno2-zno nanofibers and finally pyrrole was polym...

This paper gives an overview on the recent advances oxide/metal/oxide (OMO) flexible plastic substrates and their applications as electrodes for organic perovskite solar cells. The morphological, optical electrical characteristics of different type OMO such as: IMI (ITO/Metal/ITO), ZAZ (ZnO/Au or Ag/ZnO), NAN (NiO/Ag/NiO), TAT (TiO2/Ag/TiO2), DMD (MoO3/Ag/MoO3, SnO2/Ag/SnO2 etc.) collected from...

We performed a comparative study of electrical and thermal properties of ZnOand SnO2-based varistor. The electrical properties of commercial ZnO-based varistor are equivalent to that found in SnO2-based varistor system. In spite of this, the SnO2 showed a thermal conductivity higher than commercial samples of ZnO-based varistor, which allied with its simpler microstructure and lower dopant conc...
