Bi2MoxW[Formula: see text]O6 microspheres are synthesized by simple one-step hydrothermal method and the morphological characterizations are performed by X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), BET, scanning electron microscopy (SEM), transmission electron microscopy (TEM). The gas sensing of Bi2WO6, Bi2MoO6 and Bi2MoxW[Formula: see text]O6 is investigated. It can be concluded that the sensor of Bi2MoxW[Formula: see text]O6 has the same good sensitivity as pure Bi2MoO6 and Bi2WO6 to alcohol. It is noteworthy that the operating temperature of Bi2Mo[Formula: see text]W[Formula: see text]O6 is 200∘C which is lower than that of pure Bi2WO6 or Bi2MoO6 (240∘C), so Bi2MoxW[Formula: see text]O6 show its good property for alcohol gas sensing application.

Bi2MoxW1-xO6 的水热合成、表征和气体传感

双2莫XW[公式：见正文]O6通过简单的一步水热法合成微球，并通过X射线衍射仪（XRD），X射线光电子能谱（XPS），BET，扫描电子显微镜（SEM），透射电子显微镜（TEM）进行形态表征。Bi的气体传感2WO6, 毕2氧化钼6和毕2莫XW[公式：见正文]O6被调查。可以得出结论，Bi 的传感器2莫XW[公式：见正文]O6具有与纯 Bi 一样好的灵敏度2氧化钼6和毕2WO6到酒精。值得注意的是，Bi 的工作温度2Mo[公式：见正文]W[公式：见正文]O6是 200∘C低于纯Bi2WO6或毕2氧化钼6（240∘C)，所以 Bi2莫XW[公式：见正文]O6在酒精气体传感应用中显示出其良好的性能。
