Abstract
[中文文摘]联用电化学阳极氧化和湿化学法制备氮掺杂的TiO2纳米管阵列膜.应用SEM、XPS、DRS分析、表征,并研究该膜层的形貌、组成和光学性质以及在卤钨灯照射下降解甲基橙水溶液的光电催化活性.结果表明:氮以取代掺杂的形式进入TiO2晶格,掺氮的TiO2纳米管阵列在可见光区有较强的吸收,其光电催化性能优于纯的TiO2纳米管阵列膜. [英文文摘]N itrogen-doped TiO2 nanotube arrayw as fabricated by an electrochemica l anodic oxidation followed a wet process. XPS resu lt ind icates that the nitrogen atoms were dopedinto lattice of TiO2 nanotubes. The UV-V is spectra show that the photoabsorption of N-doped TiO2 nanotube array film is enhanced in the visible light region.Compared with theT iO2 nanotube array film, the N-doped TiO2 nanotubes exhibite a higher photocatalytic activity which is evaluated by the decomposition rate of methyl orange using the tung sten-halogen lamp as light source.
