摘要

采用电化学-水热技术,以Sr(OH)₂为锶源,TiO₂纳米管阵列为钛源,制备了SrTiO₃/TiO₂阵列复合薄膜,考察了水热时间对薄膜的组成、结构和光电性能的影响。结果表明,水热2h可以得到结晶度高、具有良好光吸收性能和光电转换性能的SrTiO₃/TiO₂复合薄膜,其光电流密度高达55μA/cm²,是纯TiO₂纳米管阵列膜的2.5倍。

Abstract

SrTiO₃/TiO₂ composite films were prepared by anodic oxidation combined with hydrothermal technique,using Sr(OH)₂ and TiO₂ nanotube arrays as raw materials.The influences of hydrothermal time on the composition,structure and photoelectric properties of films were researched.The results showed that the optimal time was 2h and the obtained composite films exhibited high crystallinity,good optical absorption and photoelectric conversion performance.A high photocurrent density of 55μA·cm^-2 can be achieved,two times than that of pure TNAs nanotube films.
