Sonochemical synthesis of hierarchical WO3 flower-like spheres for highly efficient triethylamine detection

•Hierarchical WO3 flower-like spheres have been prepared via a mild and facile sonochemical method.•The optimal WO3 sensor exhibits an excellent response of 11.6 and an ultrafast response time of 3 s to 10 ppm TEA at 205 °C.•The WO3 sensor also displays superior re-usability and low theoretical limi...
