Preparation of SnO2 nanorods by annealing SnO2 powder in NaCl flux
Journal of Materials Chemistry, 2002SnO2 nanorods having the rutile structure have been prepared by annealing fine SnO2 powder in a NaCl flux. The starting SnO2 powder, the NaCl flux, and surfactant NP9 were mixed and heated at 800 °C for 2.5 h. The nanorods have diameters of ca. 20–40 nm and lengths of up to 1 μm.

Microstructure and properties of Ag–SnO2 materials with high SnO2 content
Journal of Alloys and Compounds, 2014Abstract The microstructure and properties of Ag–SnO2 materials with high SnO2 content were investigated. The microstructure, physical properties and arc erosion behavior of Ag–SnO2 materials with high SnO2 content were studied. The results showed that the Ag–SnO2 materials with high SnO2 content show homogeneous microstructure with high hardness and

Silver layer instability in a SnO2/Ag/SnO2 trilayer on silicon
Thin Solid Films, 2012Abstract Trilayers of SnO2/Ag/SnO2 deposited on oxidized Si (100) substrates at room temperature become unstable after annealing at 100 °C and 200 °C, exhibiting five phenomena – formation of internal Ag hillocks, cracking of the top SnO2 layer above internal Ag hillocks, penetration of Ag/Ag grain boundaries by SnO2 leading to grain pinch-off ...

Characterizations of SnO2 and SnO2:Sb thin films prepared by PECVD
Vacuum, 2004Abstract Structural characterizations of tin oxide (SnO 2 ) thin films, deposited by plasma-enhanced chemical vapor deposition (PECVD), were investigated with scanning electron microscope (SEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS).

Optical Properties of SnO2 and SnO2:F - An Experimental and Theoretical Approach
2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019Thin films of SnO2 (TO) and SnO2: F (FTO) were prepared by spray pyrolysis technique on glass substrate. The UV-visible spectra show well-defined interference fringes and an average transmittance in the visible region of about 74 and 81% for TO and FTO, respectively.

Materials Characterization, 2007
The gas-sensitivity properties of SnO2 thin films as well as Ag/SnO2 and SnO2/Ag structures in an atmosphere containing propane (C3H8) were examined. The SnO2 and Ag films were deposited by a spray pyrolysis technique and vacuum evaporation, respectively. Soda-lime glass was used as the substrate for all the structures in this study.

Abstract Catalysts based on natural zeolite – clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content in TOHCLI and STOHCLI varied from 4.5 to 12.3 wt.%.

Microchimica Acta, 2018
Several nanocomposites of tin oxide with CuS, SnS or Cu@SnS were prepared and used to modify carbon paste electrodes (CPEs). The structure and morphology of the materials were studied by XRD and SEM techniques. Cyclic voltammetry and electrochemical impedance spectroscopy were applied to investigate their electrochemical properties.

Catalytic sites on SnO2 and TiO2&SnO2 for the isomerization of 1-butene
Journal of Catalysis, 1976The nature of active sites for the isomerization of 1-butene on SnO 2 and TiO 2 SnO 2 with various treatments has been studied. Over SnO 2 evacuated at 400–600 °C, a highly selective isomerization of 1-butene to cis -2-butene was observed ( cis-/trans -2-butene ≈19).
