溶胶溶剂热晶化法制备纳米TiO_2微晶

TiO_2 microcrystals prepared by the solvothermal crystallization of titania Sol.

采用二氧化钛溶胶溶剂热晶化法成功制备了锐钛矿型TiO2 纳米微晶 ,研究了不同制备条件对TiO2 晶型和粒径的影响 ,并用XRD、TEM、TG -DTG -DTA进行表征 结果表明 ,制得的TiO2 纳米微晶粒径小、粒度均匀、热稳定性好、纯度高。

The anatase TiO 2 nanosized microcrystals were successfully prepared by the solvothermal crystallization of titania sol. The influences of synthetic conditions for TiO 2 were investigated. The microstructure of TiO 2 powders was characterized by X-ray diffraction, TEM and TG-DTG-DTA methods. The nanosized anatase TiO 2 powders were smaller in diameter, even in granularity, more steady in heat treatment, purer and monodispersed.
