The development of alternative anode materials out of flexible composite nanofibers has seen a growing interest. In this paper, binary carbon nanofiber electrodes of SnO2/NiO and Sn nanoparticles are produced using a scalable technique, Forcespinning (FS), and subsequent thermal treatment (carbonization). The Sn/C composite nanofibers were porous and flexible, while the SnO2/NiO composite nanof...

Tin oxide nanoparticles have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) was used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped SnO2 sol was prepared after continuous stirring and refluxing at 40C. Thin films, prepared from SnO2 sol, have also been deposited on g...

Tin oxide (SnO2) hollow spheres modified with titanium dioxide (TiO2) nanowires (NWs) synthesized by sequential hydrothermal reactions were investigated as photoanodes for dye-sensitized solar cells. Not only does the hydrothermal treatment form numerous short TiO2 NWs on the surface of SnO2 spheres, but also passivates the surface of SnO2. Consequently, the specific surface area of the photoan...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...

Sn–O nanoparticles were prepared by levitation-jet aerosol synthesis and found to exhibit ferromagnetic behavior. X-ray powder diffraction analysis 119Sn Mössbauer spectroscopy confirmed these consist of β-Sn, SnO SnO2 phases. The maximum specific magnetization was observed for containing the SnO/SnO2 interface.

3D annealed SnO2/graphene sheet foams (ASGFs) are synthesized by in situ self-assembly of graphene sheets prepared by mild chemical reduction. L-ascorbyl acid is used to effectively reduce the SnO2 nanoparticles/graphene oxide colloidal solution and form the 3D conductive graphene networks. The annealing treatment contributes to the formation of the Sn-O-C bonds between the SnO2 nanoparticles a...

sno nanoparticles were synthesized using microwave–assisted hydrothermal method. it was noticed that at 300 and 600 watt microwave power, sno formed and remained in the tetragonal phase. at 900 watt, sno2 started appearing and a mixture of sno and sno2 phases coexisted. the particle size varied from ~2 to ~13 nm at 300 to 900 watt radiation power. the uv-v absorption spectra showed the excitoni...

Acetylene (C2H2) gas sensors were developed by synthesizing a reduced graphene oxide (rGO)-loaded SnO2 hybrid nanocomposite via a facile two-step hydrothermal method. Morphological characterizations showed the formation of well-dispersed SnO2 nanoparticles loaded on the rGO sheets with excellent transparency and obvious fold boundary. Structural analysis revealed good agreement with the standar...
