The Gas Sensitvity Character of WO3 Nanosized Material
By thermal decomposition, WO3 nanosized material was prepared as sensitive material and doped SiO2 nanosized material has been prepared using Sol-Gel process. NO2 gas-sensing elements have been manufactured with prepared material. The element is sensitive to NO2 with fairly good selectivity. Micro-structure of the material was analyzed by SEM, and the sensing mechanism was discussed.
