摘要：

In this study, a simple anodic oxidation process resulted in the successful synthesis of novel N-ion-doped TiO2 with one-dimensionally aligned and large-sized mesopores. TiO2 obtained by this anodic oxidation process possessed the high values of specific surface area and a large amount of one-dimensional mesopores with 30-50 nm diameter. Furthermore, X-ray photoelectron spectroscopy and UV-vis results suggested the possibility that these TiO2 products were composed of a N-ion-doped powder. Thus, novel structured TiO2 with large-sized mesopores was simply synthesized by an anodic oxidation of Ti metal in a nitric acid solution. These uniquely nanostructured mesoporous TiO2 products will expand possibilities for applying mesoporous TiO2 in new fields.
