以钛片为原料，采用水热法在150 ℃下反应2 h，在钛片上合成了花状结构的钛酸盐和二氧化钛纳米线。采用X射线衍射（XRD）和扫描电镜（SEM）对样品的晶体结构、形貌和尺寸进行了表征。扫描电镜（SEM）显示，样品呈花状结构，大小均匀，约2 μm。花状结构由直径约20-50 nm的纳米线组成。通过洗涤工艺和煅烧温度可以控制钛和二氧化钛的含量。该合成方法为在钛板基底上制备纳米结构的钛酸盐和二氧化钛提供了一条简单的路线，用于染料敏化太阳能电池和光催化活性应用。
Flower-like structure titanate and titania on titanium plate substrate composed of nanowires were synthesized by hydrothermal method at 150 oC for 2 h using titanium plate substrate as the starting material. The crystalline structure, shape and size of the prepared sample were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). SEM images showed flower-like structure with uniform size about 2 μm. The flower-like structure composed of nanowires with diameter about 20-50 nm. Titanate and titania could be controlled by washing process and calcination temperature. This synthesis method provides a simple route to fabricate nanostructured titanate and titania on titanium plate substrate for dye-sensitized solar cell and photocatalytic activity applications.
