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...

A sol-gel process starting with tin tetrachloride and ethylene glycol as precursors, has been successfully used to prepare nanostructured tin oxide powders. The molecular structure evolution during the process has been identified using infrared spectroscopy and the underlying reaction mechanisms of the sol-gel process are proposed. Results suggest that the -OHCH2CH2OHprevent Cl− ions from acces...

A morphology-conserved transformation yields Sn@C nanowires (UTP@CW, ∼21 wt% carbon and ∼77 wt% tin) with a high encapsulation density of ultrafine tin nanoparticles in porous carbon nanowires, which exhibit excellent reversible capacities and cycling performance for lithium ion batteries, especially at high current rates.

the aim of this research is preparation of sno2 nanowires by means of thermal chemical reaction vapor transport deposition (tcrvtd) method from sno powders. the morphology, chemical composition and microstructure properties of the nanowires are characterized using field emission scanning electron microscope (fe-sem), eds, and xrd. the xrd diffraction patterns reveal that the sno2 nanowires have...

cu2o nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used as solvent and reductant. span 80 was applied to control the morphology of cuprous oxide nanoparticles. the nano structure of the complex was characterized by x-ray diffraction measurement...

Various nanoparticles (silicon oxide, tin oxide and aluminium oxide) were mixed with poly (methyl siloxane) (Rhodorsil 224). The mixtures were sprayed on silicon substrates resulting in the formation of a rough, two-length-scaled hierarchical structure surface layer. We report that: (i) Super-hydrophobic composite films were produced with all the particles used, (ii) The effect of the particle’...

Along with high sensitivity in detecting gas, the response and recovery times of semiconductor gas sensors are of considerable importance for real life applications. In most cases, the recovery time is more than the response time. At the same time, water vapor present in the ambient, is chemisorbed on the tin oxide, SnO2 surface and the water molecules dissociate into hydroxyl species, which ac...

The aim of this study was to obtain an electrochemical device between the electrostatic interaction of the electropolymerized porphyrin {CoTPyP[RuCl3(dppb)]4}, where TPyP = 5,10,15, 20-tetrapyridilphorphyrin and dppb = 1,4-bis(diphenylphosphino)butane, and gold nanoparticles (AuNPsn-), to be used as a voltammetric sensor to determine catechol (CC). The modified electrode, labelled as [(CoTPRu4)...

Monodisperse indium tin oxide nanoparticles (ITO NPs) with high crystallinity have been synthesized by the rapid thermal injection method and the seed-mediated growth method. We demonstrate that the surface plasmon resonance (SPR) frequencies of ITO NPs can be manipulated from 1,600 to 1,993 nm in near-infrared band by controlling the composition, size, and morphology. The doping Sn concentrati...
