贵金属纳米粒子的制备、结构和应用(英文)

Preparation, structure and applications of noble metal nanoparticles

贵金属纳米粒子因其特有的光学以及化学和催化性能,正引起科技界越来越浓厚的兴趣。通常这些特性决定于这些金属粒子的粒径和形态。由于非球形粒子比各向同性的球形粒子具有更优越的性能,它们已经成为研究的焦点,人们正在努力寻找粒子形状如何影响粒子理化性能的答案。贵金属纳米粒子的形状可控合成技术已经取得了明显进展。本文就贵金属纳米粒子的形状可控合成及其应用研究的当前进展进行综合评述。

Noble metallic nanoparticles have been attracting significant scientific and technological interest because of their unusual optical properties as well as their novel chemical and catalytic properties. Usually, these unique properties are determined by the size and morphology of metal nanoparticles. Nonspherical particles become the focus of studies since they often own better properties than isotropic spherical ones and allow one to investigate how shape affects the physical and chemical properties of such structures. Considerable progress has been made on shape-controllable synthesis of noble metal nanoparticles. In this paper, the current development on shape-controllable synthesis of noble metal nanoparticles and application research has been reviewed.
