BACKGROUND Electro-oxidation of methanol in acidic solution was investigated on a Pt/SnO2 based electrocatalyst obtained by the sol-gel method. Pt/SnO2 systems were prepared by one pot synthesis using a sol-gel method and tin (IV) acetate as a precursor of SnO2 and water solution of hexachloroplatinum acid as a source of metallic phase. RESULTS The described method, thanks to its simplicity a...

In this paper we report synthesis of Au-SnO2 nanocomposite by nano-joining. It involves synthesis of Au and SnO2 colloids separately followed by post irradiation of mixed Au-SnO2 colloids. We have used 532 nm and 1064 nm wavelengths of a pulsed Nd:YAG laser and different post irradiation time. The post irradiation by 532 nm laser light results in formation of Au-SnO2 nanocomposite by nanojoinin...

coni nanowires were deposited by pulsed electrodeposition technique into porous alumina templates. the effect of off time between pulses (toff) and reductive/oxidative time (treduc/oxid) on the microstructure and magnetic properties of the coni nanowires were investigated. maximum coercivity and squareness were obtained for samples fabricated at treduc/oxid= 0.5 ms and toff =400 ms. the coerciv...

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 Fe 3+  on the surface of the SnO2-ZnO nanofibers and finally pyrrole w...

The authors present a new method for preparing thin films of SnO2 by atomic layer deposition ALD using alternating exposures to tetrakis dimethylamino tin and hydrogen peroxide. This method avoids problems of corrosion and agglomeration associated with the halogenated compound, SnCl4. Tin oxide films were successfully deposited on a variety of substrates using deposition temperatures of 50–300 ...

Tin oxide nanostructures, un-doped and Zn-doped, have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) and zinc acetate (Zn(O2C2H3)2) were used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped and Zn-doped SnO2 sol was prepared after continuous stirring and refluxing at ...

SnO2 nanoparticles were synthesized by a facile electrochemical method based on anodic oxidation of a tin metal sheet. The resulting particles, with an average diameter of about 20nm, were then loaded with varied amounts of HAuCl4, forming SnO2–Au(x) (x=0, 0.095, 0.38, 0.76, 1.9, 3.0, and 3.8 at.%) hybrid nanoparticles after calcination at elevated temperatures (700 ◦C). X-ray diffraction (XRD)...

The influence of SnO2 nanoparticles and method of their introduction in silver matrix on microstructure and physical properties such as density, porosity, hardness and electrical conductivity of Ag-SnO2 electrical contact materials were studied. The SnO2 nanoparticles were introduced by conventional powder mixing and by template method using different templates. All investigated samples were pr...

Density functional theory (DFT) modelling of the alkane-SnO2 surface interaction correctly predicts the results of the chemoresistive alkane sensing tests, provided that the highly reduced nature of the SnO2 nanocrystal surface is properly inserted in the model.
