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。
