Miniaturized electronic noses to rapidly detect and differentiate trace amount of chemical agents are extremely attractive. Use of tin oxide nanoparticles as sensing elements has been proved to significantly improve both the response time and the sensitivity of gas sensors or electronic noses. In this paper, we report the synthesis of pure tin oxide nanoparticles using a simple, convenient, and...
The present review on some metal oxide nanoparticles used for pressure sensor, various metal oxide containing such as (SnO2, ZnO, Al2O3, WO3, Fe2O3, Ga2O3, TiO2 and SiC, ...etc.) responds detection pressure measure in kbar unit through oxygen activity as oxidation or reduction process of an integrated in devices sensor (MEMS, CMOS, MOX and MOXQ1D...etc.) that devices measuring of pressure as st...
A rapid, wafer-level, dry process for in-situ synthesis, deposition of stable nanostructured, porous metal-oxide films for gas sensors is presented. Lace-like, nanostructured films of pure SnO2 featuring high porosity (98%) are selfassembled on a target substrate by flame spray pyrolysis (FSP). The nanoparticles are mainly polyhedral and monocrystalline with a grain size of 8.7 nm and crystal s...

Nano-adsorbents are emerging as potential candidates for the treatment of toxic organic pollutants. In this context, spherical SnO2 nanoparticles (NPs) synthesized through a facile hydrothermal method without usage...
Reducing the working temperature and increasing sensitivity selectivity has always been a research hotspot in field of MOS based gas sensors. In this work, improved triethylamine (TEA) sensing performance mechanism SnO2 by doping Pd have investigated. nanoparticles Pd-SnO2 with different amounts (0%, 0.1%, 0.3%, 0.5%, 0.7%) were successfully prepared hydrothermal method. The size is very unifor...
Tin dioxide (SnO2) possesses great potential as an anode material for lithium-ion batteries (LIBs) owing to its high theoretical specific capacity. However, the irreversible conversion of Sn SnO2 and enormous volume variation during charge/discharge process limit battery energy storage performance. In this study, ultrafine NiO nanoparticles (NPs) decorated on a three-dimensionally (3D) intercon...
Tin oxide nanoparticles were synthesized by electrochemical oxidation of a tin metal sheet in a nonaqueous electrolyte containing NH4F. The as-prepared nanoparticles were then thermally annealed at 700 C for 6 h. The resulting particles were characterized by a variety of experimental techniques, including X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), Raman, ...
We fabricated nitrogen dioxide (NO2) gas sensors with p-type carbon nanotubes (CNTs) / n-type tin (SnO2) nanoparticle heterojunctions using one-step dielectrophoretic assembly and investigated the effect of CNT/SnO2 ratio on their NO2 detection properties. CNTs SnO2 nanoparticles were mixed in various ratios, suspended deionized water, assembled by dielectrophoresis. The normalized response het...
In this study, tin oxide /reduced graphene (SnO2/rGO) samples were prepared by hydrothermal method. The structural characteristics, phase composition, morphology, and size of the studied X-ray diffraction, Raman scattering spectroscopy, scanning electron microscopy. Results showed that SnO2 nanoparticles had tetragonal rutile crystal structure with a ranging from 4.65 nm to 5.77 when pH was inc...
