采用磁控溅射法和溶胶-凝胶法分别在铂电极和多孔氧化铝基体上制备了具有和不具有有序穿孔孔（TFP和TF）的TiO 2基多层薄膜。TFP的晶粒尺寸小于TF的晶粒尺寸，这是由于TFP的有序多孔结构对TiO 2晶体生长的阻碍作用。与具有相似厚度和几何面积的TF和P25颗粒膜相比，TFP具有更好的光电催化活性，这是由于TFP具有单向通道和较小的晶界，从而改善了电子传输，减少了电荷复合。
TiO2-based multiple layer thin films with and without ordered-perforation pores (TFP and TF), contained a platinum electrode and a porous alumina substrate, were prepared by magnetron sputtering and sol–gel methods with and without supercritical pretreatment, respectively. The crystalline sizes of the TFP are smaller than that of TF due to obstruction effect of the ordered porous structure on the TiO2crystalline growth. Compared to TF and P25 particulate film with similar thickness and geometric area, TFP have a better photoelectrocatalytic activity for methylene blue degradation due to a unidirectional channel and small grain boundaries resulting in the improvement of electron transport and reduction of charge recombination.
