We report on nanostructured films of Al doped tin oxide grown by facile spray pyrolysis route, and their physical properties were investigated. The sprayed films were grown onto indium tin oxide (ITO) substrate at 300 °C from the precursor (SnCl4, 5H2O). The content of Al is kept at 3 % in the solution. Structural, optical, electrical and surface properties were investigated. X-rays pattern rev...

Tin oxide (SnO2-x) thin films were prepared under various flow ratios of O₂/(O₂ + Ar) on unheated glass substrate using the ion beam sputtering (IBS) deposition technique. This work studied the effects of the flow ratio of O₂/(O₂ + Ar), chamber pressures and post-annealing treatment on the physical properties of SnO₂ thin films. It was found that annealing affects the crystal quality of the fil...

A hybrid strategy for solar water splitting is exploited here based on a dye-sensitized photoelectrosynthesis cell (DSPEC) with a mesoporous SnO2/TiO2 core/shell nanostructured electrode derivatized with a surface-bound Ru(II) polypyridyl-based chromophore-catalyst assembly. The assembly, [(4,4'-(PO3H2)2bpy)2Ru(4-Mebpy-4'-bimpy)Ru(tpy)(OH2)](4+) ([Ru(a) (II)-Ru(b) (II)-OH2](4+), combines both a...

The transient photoconductive properties of tin(IV) oxide (SnO2) mesoporous films have been studied by time-resolved terahertz (THz) spectroscopy. We gain insight into carrier dynamics by measuring overall injection and trapping lifetimes using optical pump−THz probe spectroscopy, as well as the frequency-dependent complex conductivity at various pump−probe delay times. It is found that the met...

Proteins adsorbed on nanoparticles (NPs) are being used in biotechnology, biosensors and drug delivery. However, understanding the effect of NPs on the structure of proteins is still in a nascent state. In the present paper tin oxide (SnO2) NPs were synthesized by the reaction of SnCl4·5H2O in methanol via the sol-gel method and characterized by x-ray diffraction (XRD), Fourier transform infrar...

Shortly after the original synthesis of silica-based mesoporous molecular materials (MCM-41) with uniformly sized pores,1,2 the supramolecular templating approach was extended to the synthesis of non-siliceous mesoporousmaterials based onboth transition andmaingroup metal oxides because of their potential application as solid electrolyte devices, high surface area catalysts, and sorbents, as we...

The tin-doped TiO2 powders obtained by sol-gel and microwave-assisted methods were investigated. synthesis took place in a basic medium (pH 10, ammonium hydroxide, 25%) starting from tetrabutyl orthotitanate its parental alcohol. In the case of dopant, Tin(II) 2-ethylhexanoate as SnO2 precursor was used amount 1, 2, or 4 mol % SnO2. Based on thermal analysis data, thermally treated air, at 500 ...

We present an Electronic Nose (ENose), which is aimed at identifying the presence of one out of two gases, possibly detecting the presence of a mixture of the two. Estimation of the concentrations of the components is also performed for a volatile organic compound (VOC) constituted by methanol and acetone, for the ranges 40-400 and 22-220 ppm (parts-per-million), respectively. Our system contai...

Tin Oxide nanomaterial was synthesized using the horizontal vapor phase growth (HVPG) technique. The study investigated the optimum growth parameters by varying the growth temperature from 900C to 1200C and growth time of 1 hour to 5 hours. The SnO2 bulk powder with purity rate of 99.99% were placed in a sealed quartz tube with a vacuum pressure of  10 Torr and baked with the desired growth ...
