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 our previous study, we could also find that transition metals (Me3+ or Me5+) incorporated TiO2 anatase framework generated bronsted acid sites, which could be more draw water molecules, in particular, for Al and V. However, it was also revealed that the nanometer powder film fixed by a binder was easily detached from the supports in strong acidic or basic liquid phases. Therefore, this study introduces a solvothermal method to synthesize the colloidal solutions having the nano-sized AlxTi1-xOy particles. The colloidal solutions are directly coated on supports without any binders. As the result, the super-hydrophilicity on films prepared without binder in this study was more enhanced compared with those prepared with binder. 본 연구는 한국과학재단 젊은과학자연구활동지원과제 (과제번호R08-2003-000-10434-0)에 의해 수행되었으며 이에 감사를 드립니다. |
