초록 Recently, the TiO2 application has attracted a good deal of attention on purification and treatment of water and air, which are concerned in the protection of the environment.In particular, the TiO2 nano-sized powder has been widely used not only for their high photo-catalytic activity but also for their photo-induced super-hydrophilic properties. In particular, the photo-catalytic activity of metal/Ti binary oxides were enhanced compared to pure Ti oxide in many literatures. In our previous study, we could also find that transition metals (Me3+ or Me5+) incorporated TiO2 anatase framework generated brfnsted acid sites, which could be more draw water molecules. The nano-sized metal oxides, BixTi1-xOy, VxTi1-xOy, and BixVyTi1-(x+y)Oz are prepared by solvothermal method in this study. In addition, we have tried to find out the relationship between their physical properties and photocatalytic activity, particularly super-hydrophilic property.
