纳米二氧化钛-聚合物复合材料去除无机/有机污染物的研究进展

Research Progress on Removal of Inorganic/organic Pollutants by Nano-TiO_2-Polymer Composites

大量无机和有机污染物对生态环境有潜在危害。为去除这些污染物,已研发出一系列材料,其中纳米二氧化钛因制备原料低廉、制备过程简单及吸附和光催化性能优良而受到广泛关注。但纳米二氧化钛本身具有吸附量低、吸附后不易材料分离、只能吸收紫外光等缺点,需与其他材料进行复合来提高其性能。主要介绍了二氧化钛与一些聚合物材料的复合材料及用于去除无机和有机污染物的研究进展。

A large amount of inorganic and organic pollutants have potential threat to the ecological environment.For removing these pollutants,a series of materials are developed.The nano-TiO2 has low cost,simple preparation process and excellent adsorption and photocatalytic performance,so it is focused widely.However,the nano-TiO2 has some shortcomings,such as low adsorption capacity,hardly separation after adsorption and only absorbing ultraviolet light,so it needs to be combined with some othert materials to improve its performance.In this paper,the research progress on the combined materials with nano-TiO2 and its application in removing of inorganic and organic pollutants are reviewed.
