中文摘要：

利用微波等离子体技术,对钛铁矿进行了还原并获得金红石型TiO2-CNTs复合粉体.通过XRD和SEM分析了不同制备条件对产物的影响,研究了不同条件下制备的复合粉体对甲基橙光降解效率.结果表明,该方法制备出的复合粉体在可见光和紫外光下都具有较强的光催化效果,纳米碳管的结构和含量对光催化效率有较强的影响.

英文摘要：

TiO2-CNTs composite powders were prepared by reducting of ilmenite utilizing microwave plasma technology.The effect of preparation condition on products was analyzed by XRD and SEM,and photocatalysis of composite powders was studied.The results show that the composite powder have good photoactivity in UV and VIS,and it is affect by the structure and content of CNTs.
