Gas-sensing properties of the ZnO–ZFO sensor: a gas-sensing responses vs. operating temperature of the ZnO–ZFO sensor upon exposure to 100 ppm acetone gas. Cyclic resistance change curves of the ZnO and ZnO–ZFO sensors to various acetone concentrations (50–750 ppm): b ZnO sensor c ZnO–ZFO sensor. d The summarized gas-sensing response values of the ZnO and ZnO–ZFO sensors upon exposure to various acetone gas concentrations. e The gas-sensing responses of the ZnO–ZFO sensor upon exposure to various reducing gases. The ZnO–ZFO sensor exhibited superior gas-sensing response to acetone gas in this work
