| beschreibung | Pure WO 3 and Ag-WO 3 (mixed solid solutions Ag with WO 3 ) have been successfully synthesized by sol-gel method and the influences of calcination temperature on the particle size, morphology of the WO 3 and Ag-WO 3 nanoparticles were investigated. Powder X-ray diffraction results show that the hexagonal to monoclinic phase transition occurs at calcination temperature varying from 300°C to 500°C. SEM images show that calcination temperature plays an important role in controlling the particle size and morphology of the as-prepared WO 3 and Ag-WO 3 nanoparticles. The NO 2 gas sensing properties of the sensors based on WO 3 and Ag-WO 3 nanoparticles calcined at different temperatures were investigated and the experimental results exhibit that the gas sensing properties of the Ag-WO 3 sensors were superior to those of the pure WO 3 . Especially, the sensor based on Ag-WO 3 calcined at 500°C possessed larger response, better selectivity, faster response/recovery and better longer-term stability to NO 2 than the others at relatively low operating temperature (150°C). |
