Description
Summary:[Display omitted] •Usage of the ionic liquid [Bmim][BF4] as the fluorine source and morphology modifier.•The synthesis of (001) and (101) facets of TiO2 co-exposed nanocubes by a simple one-step hydrothermal method.•The TiO2 nanocubes to acetone gas at 170 oC, the detection limit is 30 ppb and the response time is only 2.2 s. Early and painless detection of type-I diabetic patients by detecting acetone concentration in their exhaled breath would be a rapid and effective means. TiO2 materials with exposed active (001) facet were synthesized mostly with HF as raw material, and the particle size was relatively large. In this work, (001) and (101) facets co-doped TiO2 nanocubes with particle size
