TiOF₂/TiO₂ nanosheets were prepared by hydrothermal processing of Ti(OBu)₄ in the presence of aqueous HF solution. The effect of different hydrothermal synthesis temperatures (140, 160, 180, and 200 °C) on the compositions, morphologies, crystal sizes, and photoelectric properties of the resulting samples was studied via various characterization methods. The photocatalytic properties of the samples were studied through photodegradation of organic pollutants such as rhodamine B (RhB), methyl orange (MO), and ciprofloxacin hydrochloride (CIP-HCl). TiOF₂/TiO₂ nanosheets prepared by hydrothermal synthesis at 160 °C exhibited the highest photocatalytic activity among these samples, and it is much more active than P25 (a benchmark photocatalyst) and TiO₂ prepared hydrothermally (without adding aqueous HF solution during the hydrothermal synthesis). A possible photocatalytic mechanism is discussed.

通过在HF水溶液的存在下对Ti（OBu）₄进行水热处理来制备TiOF ₂ / TiO ₂纳米片。通过各种表征方法研究了不同水热合成温度（140、160、180和200°C）对所得样品的组成，形态，晶体尺寸和光电性能的影响。通过光降解罗丹明B（RhB），甲基橙（MO）和盐酸环丙沙​​星（CIP-HCl）等有机污染物来研究样品的光催化性能。钛白粉₂ / TiO ₂在160°C下通过水热合成制备的纳米片在这些样品中表现出最高的光催化活性，并且比水热制备的P25（基准光催化剂）和TiO ₂（在水热合成过程中不添加HF水溶液）具有更高的活性。讨论了一种可能的光催化机理。
