The surface, crystalline structure, hole structure and aperture distribution of the microspheres synthesized were characterized by various methods, such as TEM, SEM, UV-VIS, XRD TG-DTA ,BET and nitrogen-adsorption etc.

• 对所合成的微球用TEM，IR，XRD，UV-Vis，TG-DTA和BET等表征手段进行了表面形貌、晶形结构、孔结构及孔径分布等性质的研究。 结果显示，微球是由十几个纳米的TiO_2晶粒堆积成的多孔微球，微球具有较高的降解活性。
