摘　　要： 统一尺寸、结构上有序包覆的核壳型复合材料,具有高折射率以及独特的电磁、光学和机械性质。结构上的独特性可能导致其在近红外和可见光区有完整的带隙,利用核与壳之间的相互作用,以及核对降解物的吸附等作用,可提高复合体的光催化性能。本文着重介绍核壳型TiO2的几种类型、特点及其性能,并提出其今后的发展方向。 Due to their uniform size and regularity in the structure, core-shell structure composite nanoparticles will exhibit unique properties in electromagnetism, optics and mechanism. Titania with core-shell structure maybe led to their perfect absorption in near infrared light or even visible light. Photocatalytic activities can be improved by the interaction between core and shell, as well as the absorption between core and contamination. The paper reviews the types of core-shell titania composite nanoparticles, their properties and features, and put forward their futures.
