Visible light-responsive TiO_2 thin films have been prepared on Ti foil substrate (Vis-TiO_2/Ti) by controlling the substrate temperatures during magnetron sputtering deposition process. Vis-TiO_2/Ti within H-type cell can decompose H2O separately into H2 and O_2 under light irradiation from solar simulator, while their activity being increased by calcination treatment in NH3. The introduction of UV-TiO_2 inner layer between Vis-TiO_2 and Ti foil also increases the photocatalytic activity. Moreover, dye-sensitized solar cells were fabricated using a Vis-TiO_2 electrode sensitized by a N719 dye.

通过控制磁控溅射沉积过程中的衬底温度，在钛箔衬底(VIS-TiO2Ti)上制备了可见光响应型的TiO2光响应薄膜。在太阳模拟器的光照下，H型电池内的VIS-TiO2/Ti能将H2O分别分解为H2和O2，而在NH3中焙烧处理可提高其活性。在VIS-TiO_2和钛箔之间引入UV-TiO_2内层也提高了光催化活性。此外，还利用N719染料敏化的VIS-TiO2光电极制备了染料敏化太阳能电池。
