• ; composites; gas sensor; reduced graphene oxide (rGO); ZnFe2O4 hollow spheres; Introduction As a synthetic raw material in industrial production, acetone is chemically active and extremely flammable. It is toxic if its concentration exceeds 173 ppm, and long-term exposure to acetone poses a serious threat to

• dispersion of GO to the organic solvent, in which the reaction occurrs, affects the formation of the ZnFe2O4 hollow spheres [17][39], resulting in a limitation of surface reactions. In addition, as shown in Figure 8b, the response of the sensors to 25–100 ppm acetone was also probed employing the same
