Abstract
Hierarchical Bi2WO6 microspheres are synthesized by a hydrothermal method. Morphology and structure of Bi2WO6 are analyzed by SEM, XRD, XPS, and Raman spectra. Gas-sensing properties of the as-prepared Bi2WO6 sensor are also systematically investigated. The results show the hierarchical Bi2WO6 microspheres are assembled by nanosheets and demonstrate good crystallinity. The optimal operating temperature of the Bi2WO6 sensors is 300 °C. At this operating temperature, the Bi2WO6 sensor exhibits a fast response-recovery to nitrogen oxide, suggesting its excellent potential application as a gas sensor for nitrogen oxide gas-sensing applications.
