碳纳米管负载TiO_2的光催化强化机理及复合物制备的研究进展

Enhanced Photocatalysis Mechanism and Progress in Preparation of Carbon Nanotube-TiO_2 Nanocomposites

作为优异的新型功能材料和结构材料,以碳纳米管负载光催化剂TiO_2的研究吸引了高度关注。本文主要根据近五年的国内外研究状况,对碳纳米管作为光催化剂TiO_2载体,对抑制TiO_2光生电子-空穴复合及对TiO_2可见光敏化的机理,以及TiO_2/碳纳米管复合光催化剂的制备进展进行了综述。

Loading photocatalyst TiO2 by Carbon nanotube （CNT）, an excellent new functional and structural material, has attracted prodigious attentions. Basing on the domestic and international research literatures in latest five years, the studies on TiO2/CNTs nanocomposite are systematically reviewed, including the mechanisms of inhibiting the recombination of light generated electronic-hole in TiO2 and the visible photosensitive of CNTs to TiO2, as well as the progress in preparation of the TiO2/CNTs nanocomposite.
