Abstract
Because tin dioxide has advantages of stable physical
chemical properties and superior electrical conductivity
tin dioxide-based gas sensor has characteristics of high sensitivity
long life
good stability.Nanostructured tin dioxide material is prepared by hydrothermal method and then indirectly-heated gas sensor is fabricated. By adjusting the amount of Na OH
the morphology of nanostructured tin dioxide materials with different concentrations are studied
and the experimental platform is built to experimentally investigate the sensitivity
selectivity and repeatability under different morphologies
