在过去的几年里，工业活动的激增不可避免地导致了环境中污染物流量的增加，这仍然是各国面临的复杂挑战。随着碳纳米管（CNT）的发展，人们对该领域的研究兴趣不断增长。近来，将TiO 2与CNT组合作为改善光催化活性的手段正被越来越多地研究，并且增强的证明是邦蒂富尔。本文综述了文献，并强调了最近的发展在TiO 2/CNT纳米复合催化剂和最近开发的形态。此外，提出的增强机制进行了总结和讨论。然后，本文提供了一个最新的图片的合成技术，这些纳米复合催化剂和它们的光催化反应与有机和无机污染物在液体和气体环境。最后，这些纳米复合催化剂的未来前景与挑战。
For the past couple of years, the surge of industrial activities that inevitably resulted in an increasing flux of pollutants in the environment still remains n intricate challenge for nations. With the advancement of carbon nanotube (CNT), there has been a consistently growing interest in the research area. Recently, combining TiO2 with CNT is being increasingly examined as a means to improve photocatalytic activity, and demonstration of enhancements are bountiful. This paper surveys the literature and highlights recent development in the TiO2/CNT nanocomposite catalysts and more recently developed morphologies. Furthermore, the proposed mechanisms of enhancement are summarized and discussed. The paper then provides an up-to-date picture of the synthesis techniques for these nanocomposite catalysts and their photocatalytic reactions with organic and inorganic pollutants in both liquid and gaseous environments. Finally, the future perspectives together with the challenges for these nanocomposite catalysts are presented.
