Preparation of TiO2 Nanopowders By Solvothermal Synthesis

摘要

TiO2 nanopowders were synthesized by solvotherrnal synthesis method.Effects of different solvents and dodecylbenzenesulfonic acid sodium on the properties of TiO2 nanopowders were investigated.The formation mechanism of TiO2 microflowers was discussed.The results showed that with the increasing of carbon chain of alcohol,the diameter of TiO2 nanopowders increased.Flowers-like TiO2 nanostructures were produced with 0.115M SDBS.Flowers-like TiO2 nanostructures were composed of TiO2 cuboid nanorods,and the length,width and thickness of cuboid nanorods were 1 ～ 2 μm,100nm and 100nm,respectively.
