在普通无机盐存在下，采用H2O2在80°C下直接氧化钛基体制备了TiO2纳米片阵列薄膜。随后在450°C下的热处理将无定形薄膜转变为无定形相，而不破坏纳米片的形态。采用扫描电子显微镜（SEM）和X射线衍射（XRD）对所制备的TiO2纳米片薄膜进行表征。扫描电子显微镜（SEM）观察表明，纳米片几乎垂直于钛基体表面生长。以亚甲基蓝为降解对象，考察了其光催化活性.此外，还测量了光电流，以研究光生电子和空穴的分离效率。
Titania nanosheet array film was prepared through direct oxidation of titanium substrate by H2O2at 80°C in the presence of common inorganic salts. A subsequent heat treatment at 450°C transformed the amorphous thin film to anatase phase without destroying the morphology of nanosheets. The as-prepared TiO2nanosheet film was characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD). The SEM images of the samples indicated that the nanosheets grew nearly vertical to the surface of Ti substrate. The photocatalytic activity was evaluated by degradation of methylene blue under UV irradiation. Furthermore, photocurrent was also measured to investigate the separation efficiency of photogenerated electron and hole.
