采用经济、简单的一步水热法制备了具有层状钙钛矿结构的新型蒲公英状Bi2WO6纳米结构。各种表征结果证实了制备的Bi2WO6单相蒲公英具有均匀的由边缘纳米片组成的蒲公英样形貌。利用这种无与伦比的三维形态，n型半导体3D Bi2WO6蒲公英制成的气体传感器在270℃的较低最佳工作温度下，具有独特的良好的乙二醇传感性能，即高响应值，优异的重复性，检测最小限为1 ppm等。因此，新型3D Bi2WO6蒲公英可能是一种超敏感的乙二醇候选半导体材料。
The novel dandelion-like Bi2WO6 nanostructures with layered perovskites were successfully fabricated through a one-step hydrothermal path which is economic and simple. The fact that the single phase Bi2WO6 dandelion was prepared and the sample possessed uniformly dandelion-like morphology comprising of edge nanosheets was confirmed by multifarious characterized results. Benefiting from such an unparalleled 3D morphology, n-type semiconductor 3D Bi2WO6 dandelion was made into gas sensor who exhibited unique good ethylene glycol sensing properties at a lower optimum operational temperature of 270 degrees C, i.e., high response value, excellent repeatability, a detection minimum limit of 1 ppm and so forth. Hence the novel 3D Bi2WO6 dandelion could be an ultra-sensitive ethylene glycol candidate semiconductor material.
