    摘要:

    用浸漬提拉法在玻璃基片上制備TiO2納米薄膜和TiO2／ZnFe2O4納米復(fù)合薄膜，利用X射線衍射(XRD)、掃描電鏡(SEM)、原子力顯微鏡(AFM)、X射線光電子能譜(XPS)以及紫外．可見(jiàn)分光光度計(jì)等分析測(cè)試方法對(duì)制備薄膜的相結(jié)構(gòu)及光吸收性能進(jìn)行了分析和表征。結(jié)果表明，在500℃熱處理下薄膜為銳鈦礦型，粒度在20nm～30nm；復(fù)合后薄膜的光吸收邊發(fā)生了紅移，不同的復(fù)合方式影響亞甲基藍(lán)染料的光催化降解效率。

    Abstract:

    TiO2 nano thin film and TiO2/ZnFe2O4 nano composite thin film were prepared on glass substrate by dip coating process. The films were studied by X-ray diffraction (XRD), scanning electron microscope (SEM), X-ray photo-electron spectrum (XPS), atom force microscope (AFM), Uv-vis spectroscope, etc. The obtained films were analyzed and were proved to be anatase alone. At the same time, the photo absorption edge of the composite film was red-shifting. Finally, photocatalytic decomposition properties of methylene blue were tested and discussed.
