摘要/Abstract

摘要： 采用直接真空吸附钛酸四丁酯后水解法制备了以活性炭为载体的负载型TiO₂光催化剂,以间二氯苯为探针分子研究了催化剂光催化降解反应性能.实验结果表明:随着热处理温度的不同,催化剂的光催化活性有很大的变化.对催化剂多次反复使用,其活性基本不变.

关键词: TiO₂, 活性炭, 光催化, 间二氯苯

Abstract: Photocatalysts of TiO₂ supported on activated carbon was prepared by a vacuum absorption-hydrolysis method.The photocatalytic activity was investigated with 1,3-dichlorobenzene as a probe molecule.The results indicate that the supported TiO₂ catalyst was affected by the heating temperature.And recycled times had a little effect on its photocatalytic activity.

Key words: TiO₂, activated carbon, photocatalysis, 1,3-dichlorobenzene
