摘　　要：二氧化钛有着较高的光催化性能,因此在光电转换、光催化等领域上有着广泛的应用,但其催化效率却不是很高,近年来,越来越多的人研究以二氧化钛为基的核壳结构纳米材料。文章根据不同的制备方法,从表征方法、结构特征和催化活性等方面介绍了近年来一些以二氧化钛为基的核壳结构纳米材料的制备进展并展望了二氧化钛基核壳结构纳米材料的发展前景。TiO2 has been widely used in photoelectric conversion, photocatalytic and other fields for its higher photocatalytic performance. But the catalytic efficiency of TiO2 is not so high. In recent years, more and more people have studied on the core-shell structure of nanomaterials which is on the base of TiO2. According to the different preparation methods, this paper will introduce the preparation progress of core-shell nanomaterials on the base of TiO2 from the characterization methods, structure characteristics and catalytic activity. At last, the development prospects of the TiO2-based nanomaterials with core-shell structures are proposed.
