•The multishelled structure is conducive to the adsorption of gas molecules.•The sensor based on our sample has a relatively low working temperature of 200 °C.•The multishelled SnO2 has the sensing excellent performance for acetone detection.
In this paper, the multishelled hollow SnO2 microspheres were successfully synthesized using carbon microspheres as a template. The structure and morphology were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). Moreover, the sensor based on the product showed excellent gas-sensing performance to acetone at 200 °C, and the response and recovery time were about 10 s and 12 s, respectively. The present study could be applied to acetone detection.
