中文摘要:
      特制的氧化钛薄膜由于其特有的优势广泛用于绿色能源领域。在这篇文章中,采用电子束蒸发系统制备氧化钛薄膜并分别在氢气和空气中退火,在氢气中退火的样品由于其稳定性强能在空气中保持淡黄色将近一年。氧化钛薄膜的结构,形貌,光谱和光催化性能被详细讨论。在氢气中退火的薄膜比在空气中退火的薄膜具有更好的光催化性能,结果表明氢气中退火的样品通过Ti3+掺杂能很好地调控电子结构从而提高光催化效率。Ti3+的存在缩小了带隙。

英文摘要:
      Tailored production of titanium dioxide thin films (TTFs) are widely used in green energy field due to their outstanding advantages. In this work, the TTFs wereSprepared by the electron beam evaporation system and annealed in air and H2 respectively. With excellent stability, samples annealed in H2 maintain their pale yellow in the air for nearly a year. The structure, morphology, spectral and photocatalytic properties of TTFs have been observed and discussed detailedly. Titanium oxide films annealed in H2 have better catalytic performance than those annealed in air. The results show that Ti3+ can improve photocatalytic efficiency since the electronic structures of TTFs annealed in H2 can be finely tuned by the doped Ti3+. The existence of a Ti3+ induced an electronic band below the conduction band and narrows the band gap.
