采用和频光谱和石英晶体微天平研究了TiO2表面的界面水结构和紫外光照射后的界面水结构。结果表明，紫外线照射导致的量的增加，不仅作为一个整体的吸附水，但也有序的吸附水的TiO 2表面上，确认增加的表面的亲水性。
The interfacial water structures at surfaces of an as-prepared TiO2 and of the TiO2 after UV irradiation were investigated by sum frequency generation (SFG) spectroscopy and quartz crystal microbalance (QCM). It was shown that UV illumination led to an increase in the amount not only of adsorbed water as a whole but also of the ordered adsorbed water on the TiO2 surface, confirming the increase of hydrophilicity of the surface.
