Enhanced pseudocapacitive performance of SnO2, Zn-SnO2, and Ag-SnO2 nanoparticles

Ionics, 2018
Metal-doped tin oxide is gathering interest in the field of energy storage and power supply devices, particularly in supercapacitors applications. In the present study, we adopt a hydrothermal method to synthesis SnO2, Zn-SnO2, Ag-SnO2 nanoparticles at suitable conditions of temperature, pH, reaction time, and capping agents (CTAB).

Infrared studies on SnO2 and Pd/SnO2

Catalysis Today, 2001
Abstract The peculiarities of the IR studies of adsorption on semiconducting oxides are reviewed with special attention to SnO2. Absorption by free electrons is very strong in reducing atmospheres and well-defined conditions are required to get vibrational information on the nature of surface species.

SnO2:Eu nanocrystallites in SnO2 monolithic xerogels

Chemical Physics Letters, 1992
Abstract By simple room temperature broad band time-resolved spectroscopy it was possible to discriminate different Eu3+ spectra in SnO2 monolithic gels obtained by a sol—gel synthetic route. Nanocrystalline domains of the cassiterite-like SnO2:Eu could be easily identified in the transparent medium.

E-beam deposited SnO2, Pt–SnO2 and Pd–SnO2 thin films for LPG detection

Thin Solid Films, 1999
Abstract The electron-beam evaporation method was used to deposit undoped and Pt (or Pd) doped SnO 2 thin films. After careful study of their physical properties, SnO 2 thin films with suitable growth conditions were selected for probing their response to LPG and other common household gases.

Microstructure and structure of NiO–SnO2 and Fe2O3–SnO2 systems

Applied Surface Science, 2003
Abstract The microstructure and the structure of NiO–SnO 2 and Fe 2 O 3 –SnO 2 were studied by X-ray diffraction (XRD) and adsorption analysis (BET). The segregation of Ni or Fe on the surface of SnO 2 was observed even in specimens with 30 mol% addition.

Electron spectroscopic studies on films of SnO2 and SnO2:Sb

Surface and Coatings Technology, 1987
Abstract Pure and antimony-doped SnO2 films have been deposited by two different techniques: metal-organic chemical vapour deposition (MO-CVD) and spray pyrolysis of SnCl4 in the presence of air with different concentrations of antimony. X-ray and UV photoelectron spectroscopic studies have been carried out on these films and the combined data from ...

SnO2@MCC and SnO2@C Composites: Synthesis and Properties

Russian Journal of Inorganic Chemistry, 2019
A method is advanced to prepare SnO2@MCC composites in the course of hydrolysis of flax cellulose fiber by SnCl2-containing 10% aqueous nitric acid. The thus-prepared SnO2@MCC composites have a tin dioxide average crystallite size of 3.8 nm. SnO2@MCC pyrolysis under an inert atmosphere yield carbon composites SnO2@C and SnO2/Sn@C.

Electroless deposition of Sno2 and antimony doped SnO2 films

Journal of Physics and Chemistry of Solids, 1985
Abstract Thin polycrystalline films of SnO 2 and antimony doped SnO 2 have been prepared by simple economic electroless deposition technique. The transmittance in the visible range and the reflectance in the i.r. range for SnO 2 films are ∼80% and ∼70%, respectively, with resistivity ∼10 −2 Ω cm.

Preparation of porous SnO2 helical nanotubes and SnO2 sheets

Materials Chemistry and Physics, 2013
abstract We report a surfactant-free chemical solution route for synthesizing one-dimensional porous SnO 2 helical nanotubes templated by helical carbon nanotubes and two-dimensional SnO 2 sheets templatedby graphite sheets. Transmission electron microscopy, X-ray diffraction, cyclic voltammetry, and galva-nostatic dischargeecharge analysis are used to
