Self-organized TiOF2 nanotubes have been synthesized by a one-pot solvothermal method. Different solvent ratios have been used during material preparation. When choosing the equal ratios of acetic acid and trifluoroacetic acid (TFA) as the solvent, uniform TiOF2 nanotubes were obtained. It is found that the solvent ratios alter their crystalline nature and surface morphology. X-ray diffraction (XRD) pattern indicates that the sample is pure and single-crystalline in nature. Scanning electron microscopy (SEM) morphology points out that the TiOF2 nanotubes with a length of approximately 2–3 μm, which composed of self-assembled nanorods. This distinct construction is advantageous to enhance the photocatalytic hydrogen (H2) evolution under UV–vis irradiation. Photocatalytic examination reveals that the TiOF2 nanotubes have a high photocatalytic H2 evolution rate (~800 μmol h−1 g−1) than other attempted candidates. The excellent photocatalytic H2 evolution attributes to the tube-like morphology and large separations of charge carriers.

自组织单晶TiOF 2纳米管的轻松合成,用于光催化制氢

通过一锅溶剂热法合成了自组织的TiOF 2纳米管。在材料制备过程中已使用了不同的溶剂比例。When choosing the equal ratios of acetic acid and trifluoroacetic acid (TFA) as the solvent, uniform TiOF 2 nanotubes were obtained. 发现溶剂比例改变了它们的结晶性质和表面形态。X射线衍射(XRD)图表明样品是纯净的单晶。扫描电子显微镜(SEM)形态指出,TiOF 2纳米管的长度约为2-3μm,由自组装的纳米棒组成。这种独特的结构有利于增强光催化氢(H 2)在紫外线可见辐射下的演变。光催化检查显示,TiOF 2纳米管比其他尝试的候选物具有更高的光催化H 2释放速率(〜800μmolh -1  g -1)。优异的光催化H 2析出归因于管状形态和载流子的大分离。
