摘要：

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.
