Abstract For real-application gas sensors, high performances (response, selectivity, response/recovery time and stability) are demanded. An effective strategy is applying nanomaterials in sensors. In this study, the anatase TiO 2 flower-like (FLNMs) prepared through a one-step hydrothermal method which exhibit high-performance toward acetone vapor. FLNMs sensors property characterized at optimal working temperature of 330 °C with selectivity (acetone), response ( S = 33.72 250 ppm acetone), linear dependence R 0.9913), (46/24 s acetone) long-term stability (30 days). These demonstrate that get performance for sensor. Moreover, limit detection 0.65 lower than exhaled air diabetes (0.8 ppm), indicating sensor gets potential application medical diagnosis.
