TiOF2, which has remarkable electrochemical and optical properties, is used in various applications such as Li-ion batteries, electrochemical displays, and photocatalysts. In addition, it is possible to utilize the template which is allowed to synthesize fluorine doped TiO2 powders with hollow or faceted structures. However, common synthesis methods of TiOF2 powders have some disadvantages such as the use of expensive and harmful precursors and batchtype processes with a limited production scale. In this study, we report a synthetic route for preparing TiOF2 powders by using an inexpensive and harmless precursor and a continuous ultrasonic spray pyrolysis process under a controlled atmosphere to address the aforementioned problems. The synthesized powder has an average size of 1 μm, a spherical shape, a pure TiOF2 phase, and exhibits a band-gap energy of 3.2 eV.
