合成锐钛矿型单晶TiO2（001）正方纳米片阵列薄膜及生长机制研究

In this paper，single crystalline anatase TiO2 tetragonal nanosheet-array film on a transparent conductive fluorine-doped tin oxide (FTO) substrate was successfully prepared by hydrothermal method. The products were characterized with XRD, SEM and TEM measurements. The formation mechanism of the tetragonal (001) TiO2 nanosheets is discussed and the effect of growth parameters, such as acidity, growth time, growth temperature, initial reactant concentration and additives, are investigated. This work demonstrates a clean and effective route to the morphology-controlled preparation of large area single-crystalline TiO2 nanostructured array films on FTO glass.
