| 摘 要： | 碳纳米管这种一维结构的新材料的发现为物理、化学、材料科学和纳米科学开辟了全新的研究领域。近年来,非碳无机类富勒烯(InorganicFullerene-like,简称IF)纳米管也受到人们的广泛关注。迄今为止报道的无机类富勒烯纳米管主要有:过渡金属硫化物(MS2,M=W,Mo,Nb)犤1～3犦、V2O5犤4犦、Al2O3犤5犦纳米管等。其中金属氧化物纳米管在催化、吸附、单电子晶体管等方面有着潜在的应用前景。TiO2纳米粉体和纳米膜材料在太阳能的存储与利用、光电转换、光致变色及光催化降解大气和水中的污染物等方面具有广泛的应用。为了提高其光催化活性和对…

| Abstract: | Using Fe doped titania powders as the precursor, Fe doped TiO2 nanotubes with small diameter of 10nm were obtained by hydrothermal method. The doped titania powders have two different crystalline phases, anatase and rutile of which the average particle diameters are 30.3nm and 41.7nm, receptively. The products were characterized by TEM, XRD and EDS. The results showed that Fe doped TiO2 nanotubes of 200nm in length could be obtained from Fe doped rutile powder, and have higher yields. The formation mechanism of long titania nanotubes was suggested in the light of the relative stability of crystalline phase. |
