研究了最近提出的连续水热法制备尺寸可控的锐钛矿型纳米二氧化钛的优点。利用X射线衍射仪、比表面积测量、高分辨电子显微镜和拉曼光谱对采用这种方法和软化学方法制备的纳米粉末进行了表征，重点是用低频拉曼测量确定了纳米粉末的尺寸分布。连续热液路线更适合于产生较窄的粒度分布。
The advantages of a recently presented continuous hydrothermal elaboration route for size-controlled anatase TiO2 nanoparticles are investigated. Nanopowders prepared by this route and using a soft chemistry route are characterized using X-ray diffraction, surface area measurements, high-resolution electron microscopy and Raman spectroscopy with an emphasis on the determination of the size distribution with low-frequency Raman measurements. The continuous hydrothermal route is shown to be more suitable for producing narrower size distributions.
