Abstract

Abstract: The pyrolysis method has been used for decomposing InCl₃ so as to form In₂O₃,and depositing uniformly on the surface of TiO₂ nanotube(TNAs) which was prepared by anodic oxidation method,and the photo-catalytic activity of In₂O₃-TNAs was tested by the photo-catalytic degradation of Rodamine B(RhB). The results show that after combined with In₂O₃,the photo-catalytic activity of In₂O₃-TNAs binary system is enhanced dramatically compared with that of pure TNAs. In addition,pyrolysis deposition is characterized by simple process,low costs,and advantageous to volume production and industrial production of photo-catalysts,providing a new concept for the deposition of metallic oxidant semi-conductors.

Key words: photo-catalysis, anodic oxidation, TiO₂ nanotube, pyrolysis, In₂O₃

摘要： 通过热解法分解InCl₃形成In₂O₃并均匀沉积于通过阳极氧化法制备的TiO₂纳米管（TNAs）表面，并通过光催化降解罗丹明B（RhB）来测试In₂O₃-TNAs的光催化活性。结果表明，复合In₂O₃后TNAs的光催化活性显著提升。此外热解沉积工艺简单、成本低，有利于光催化剂的批量、工业化生产，为金属氧化物半导体的沉积提供了新思路。
