摘要:

采用Sol-gel法制备了悬浮型TiO2纳米微粒。用GC研究了不同烧结温度及不同Sol-gel制备参数条件下制备的TiO2对苯系物降解效率的影响,并用XRD和TEM对制备的纳米TiO2微粒进行了表征。研究结果表明,制备的悬浮型TiO2具有对有机污染物降解效率高等优点,是一种具有晶粒尺寸小的纳米微粒。

Abstract:

Nano-sized TiO2 suspension particles have been prepared by Sol-gel method. The capillary GC has been used to research the influence of different calcinations temperature and technical conditions of the degradation efficiency of the prepared TiO2 on phenyl-compounds,and the properties of the prepared catalyst are characterized by TEM and XRD. The research results show that the prepared suspending TiO2 has high degradation efficiency for phenyl-compounds and nano-sized small particles.

Key words: Sol-gel method, TiO2, photo-catalyst, nano-sized, phenyl-compounds
