虽然bi2wo6已广泛应用于各个领域，但其在气敏方面的潜在应用却很少被报道。本文首次采用一步水热法制备了带裂纹的bi2wo6块体，并采用多种技术对其晶体结构和形貌进行了表征。采用静态传感器测试系统对块体Bi2WO6的气敏性能进行了研究。结果表明，bi2wo6具有检测三乙胺气体的超快响应时间（7 s）和高选择性（8 s），是一种很有前途的三乙胺传感器材料。此外，还讨论了bi2wo6的气敏机理。
Although Bi2WO6has been widely used in a variety of fields, its underlying application in gas sensing have been seldom reported. In this work, the bulk Bi2WO6with cracks were fabricated via one-step hydrothermal method for the first time, and its crystal structure and morphology were characterized by many techniques. The static sensor testing system was employed to investigate the gas sensing performance of bulk Bi2WO6. The results indicate that Bi2WO6is capable of detecting triethylamine gas with ultrafast response time (7 s) and recovery speed (8 s), high selectivity, which showing the Bi2WO6is a promising materials for fabricating triethylamine sensors. In addition, the gas sensing mechanism of Bi2WO6was also discussed.
