摘要：
Titanium dioxide (TiO2) nanoparticles were prepared by resistive heating Ti filament under an oxygen atmosphere. The obtained nanoparticles were confirmed to be a tetragonal crystal TiO2 and the particle size increased with increasing the oxygen pressure. The NO2 gas sensing properties of the TiO2 nanoparticles were investigated. All the sensors made of TiO2 nanoparticles with different particle sizes exhibited the maximum sensitivities to 1 ppm NO2 at a relative low operating temperature of 150 degrees C. Comparing with the large particle size of TiO2 nanoparticles, the ones with the smallest particle size exhibited the highest sensitivity and the best response and recovery characteristic to various NO2 gas concentrations.
