核/壳结构复合纳米材料研究进展

Research Progress in Nanocomposites with Core/shell Structures

核/壳结构复合纳米材料是具有特殊性能的功能材料,是由一种纳米材料通过化学键或其他相互作用将另一种纳米材料包覆起来形成的纳米尺度的有序组装结构。这种结构可以产生单一纳米粒子无法得到的许多新性能,因而具有许多不同于核、壳材料的独特的光、电、磁、催化等物理和化学性质。主要介绍了核/壳型复合纳米材料的特点、形成机理以及制备方法,并结合最近的科研工作对其研究进展进行了综述。

The nanocomposite with core/shell structures is an ordered assembly system in which one nanomaterial is covered by another nanomaterial via chemical bond or other interactions. These structures present many new functions and particular optical, electric, magnetic, or catalytic properties which could not been obtained from single nanoparticles. In this paper, the research advance, properties and synthesis methods of the core/shell nanostructures are reviewed. And many of the examples presented in this field are drawn from the recent work.
