In this study, solid and hollow microcubes of ZnSnO3 were synthesized via the co-precipitation method. To investigate the structural properties of these microcubes, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, field-emission scanning electron microscopy (FE-SEM), and (BET) were utilized, demonstrating the high purity of the ZnSnO3 microcubes. Subsequently, to conduct sensing tests of the synthesized particles, a suitable solution was prepared and coated onto a gold-coated substrate, and gas sensing tests were performed for solid and hollow ZnSnO3 microcubes. The results indicated that the hollow ZnSnO3 microcube sensor exhibited a superior efficiency response at a temperature of 220 oC, with a response and recovery time of 34 and 35 s, efficiency response of 53, for acetone gas at a concentration of 100 ppm compared to the solid sample. also, this sensor displayed a better response to acetone gas compared to other gases such as ethanol, methanol, benzene, toluene, and NH3.
