Abstract:

Using gas-state reaction, Nanometer WO3 was synthesized by gasstate reaction with tungsten filament, WO3 mixed with TiO 2 made by Sol-gel method was made up into gas-sensor to H 2S. The gas-sensing measurement results revealed that these sensors with a certain sensitivity put into H2S gas of density (about 10 -6) and present good response-recovery characteristics. By analyzing micro-structure of the material, the mechanism of these sensors was discussed.
