Abstract

Abstract: The Bi-TiO₂ nanotube(Bi-TNAs) photocatalyst has been prepared via anodization process,and simple photo-deposition method. Its appearance,crystalline phase and optical absorption property have been characterized. The results reveal that the flaky Bi nano-sheet in metallic phase is successfully deposited on the surface of TiO₂ nano-tube arrays(TNAs). The test on photocatalytic degradation of RhB shows that the photo-catalytic degradation capa-bility is significantly enhanced,compared with that of TNAs. Elemental Bi nano-sheet as an electronic trap can cap-ture photo-generated electrons of TiO₂,so as to prolong the life-time of current carrier,slow down electron-hole recom-bination rate and enhance the TNAs photocatalytic degradation activity for RhB.

Key words: photocatalysis, TiO₂ nanotube, anodization, photo-reduction, Bi

摘要： 采用阳极氧化法及简易光沉积法制备了一种Bi-TiO₂纳米管（Bi-TNAs）光催化剂，并对其形貌、晶相以及光吸收性能进行表征。结果显示，薄片状的金属相Bi微米片成功沉积在TiO₂纳米管阵列表面。光催化降解罗丹明B实验显示，Bi-TNAs的光催化降解性能比TNAs显著增强。单质Bi微米片作为电子陷阱可捕获TiO₂的光生电子，延长载流子寿命，降低电子-空穴复合速率，增强TNAs光催化降解罗丹明B的活性。
