Conclusions In this paper, ZnO-TiO2 -rGO ternary composites have been ready by the hydrothermal strategy. For experimental comparison, ZnO, TiO2 , and ZnO-TiO2 nanomaterials had been also prepared for gas-sensitive testing. The morphology and structure on the four synthesized nanomaterials were also characterized by XPS, HRTEM, SEM, and XRD. The results show that the ternary ZnO-TiO2 -rGO nanomaterials have an optimal sensor operating temperature of 145 C in addition to a response of 28 to 100 ppm butanone vapor. Not only can butanone vapor be detected at 63 ppb but additionally the ternary ZnO-TiO2 -rGO nanomaterials have greater selectivity than ZnO, TiO2 , and ZnO-TiO2 nanomaterials. For that reason, the experimental outcomes show that the ZnO-TiO2 -rGO sensor has improved sensing overall performance to butanone vapor.Author Contributions: Conceptualization, F.M.; methodology, Z.L. and F.M.; validation, Y.Y., F.M.; formal analysis, Z.Y. and Y.Y.; investigation, Z.L.; sources, F.M.; information curation, Z.Y.; writing– original draft preparation, Z.L.; writing–review and editing, Z.L.; visualization, Y.Y.; supervision, F.M.; project administration, Z.Y.; funding acquisition, F.M.
