摘要:

采用水热法合成了钛酸盐纳米管薄膜, 通过光催化还原反应将Ag/AgNO3纳米粒子负载其上, 制得Ag/AgNO3修饰钛酸盐纳米管薄膜, 并对其形貌、结构和化学组成进行了表征. Ag/AgNO3修饰后钛酸盐纳米管薄膜的性能发生了明显变化, 不仅展示出光致变色的性能, 而且光催化活性得到显著提高, 此外, 纳米管表面产生出的活泼自由基协同具有强氧化能力的Ag+能有效抑制或杀灭细菌, 使薄膜具有优异的抗菌性能.

Abstract:

Ag/AgNO3 modified titanate nanotubes films were prepared by hydrothermal method and followed by photo-reduction method. The morphology, structure and composition of the product were characterized. The film exhibited high photocatalytic actibity and photochromic property. Ag/AgNO3 acted as the active center and generated·O-2, HO2· and ·OH. These strong oxidative free radicals not only degraded the organic matter, but also eliminated bacterium. Ag/AgNO3 modified titanate nanotubes films would be a promising material in various of application areas in virtue of its excellent photocatalytic activity, photochromic property and antibacterial activity.

Key words: Titanate nanotubes film, Ag/AgNO3, Photocatalytic activity, Photochromic property, Antibacterial activity
