Abstract

Films of TiO₂ nanorods prepared under different conditions of hydrothermal synthesis were studied. With an increase in the hydrothermal synthesis temperature at a synthesis time of 24 h, the length of the TiO₂ nanorods formed first increases and then decreases, and the nanorod diameter changes. The TiO₂ film consisting of nanorods 4100 nm long and 100 nm in diameter, prepared at 180°C, exhibits the highest photocatalytic activity. This effect is predominantly associated with high specific surface area of the samples.

水热合成条件对二氧化钛纳米棒光催化活性的影响

摘要

研究了不同水热合成条件下制备的TiO ₂纳米棒薄膜。在合成时间为24 h时，随着水热合成温度的升高，形成的TiO ₂纳米棒的长度先增加后减小，纳米棒直径发生变化。由长 4100 nm 和直径 100 nm 的纳米棒组成的 TiO ₂薄膜，在 180°C 下制备，表现出最高的光催化活性。这种效应主要与样品的高比表面积有关。
