Synthesis and Gas Sensitivity of SnO₂ Nanoparticles

Abstract:

Tin dioxide (SnO₂) nanoparticles have been synthesized in bulk quantity by thermal evaporation of SnO powder. The x-ray powder diffraction (XRD) analysis indicates that the nanoparticles are the tetragonal rutile structure of SnO₂. Scanning electron microscopy (SEM) analysis shows that the size of the synthesized SnO₂ nanoparticles is relatively homogeneous with diameter of about 10 nm. Gas-sensing components have been manufactured with the SiO₂ nanoparticles. Their performances indicate that it has high sensitivity and selectivity to LPG, and the max sensitivity appears at 280°C, compared with C₂H₅OH, H₂, CO and CH₄.
