纳米材料(又称超细微粒、超细粉未)是处在原子簇和宏观物体交界过渡区域的一种典型系统,其结构既不同于体块材料,也不同于单个的原子。其特殊的结构层次使它具有表面效应、体积效应、量子尺寸效应等,拥有一系列新颖的物理和化学特性,在众多领域特别是在光、电、磁、催化等方面具有非常重大的应用价值。
Nanomaterials (also known as ultrafine particles, ultra-fine powder) is a typical system in the transition region between the clusters and the macroscopic objects. Its structure is different from that of bulk materials and individual atoms. Its special structure level makes it have surface effect, volume effect, quantum size effect, etc. It possesses a series of novel physical and chemical properties and has very important application value in many fields, especially in light, electricity, magnetism and catalysis .
