贵金属纳米颗粒由于其独特的光学及催化性能引起了人们的广泛关注,而这些性能与纳米颗粒的尺寸、形貌、结构组成等密切相关.目前如何有意识地控制晶体生长过程,以得到人们需要的纳米结构和组成,仍具有相当大的挑战性.文章重点介绍了利用具有特定形貌和晶面组成的金纳米棒(Au nanorods)作为种子,借助形成核/壳结构,诱导了Ag,Pd,Pt棒状纳米结构的形成,并实现了对杂化纳米结构光学和催化性能的调控,进一步扩展了贵金属纳米结构的应用范围.作者的研究结果表明,形成杂化纳米结构是性能调控的一种有效方式. Due to their unique optical and catalytic properties, noble metal nanoparticles attract people’s attention, and these properties are closely related to the size, morphology, structure and composition of the nanoparticles, etc. At present, how to consciously control the crystal growth process so as to obtain the desired Nanostructures and compositions are still quite challenging.In this paper, we focus on the use of Au nanorods with specific morphology and crystal facets as seeds, and induce the formation of Ag, Pd, Pt rod-shaped nanostructures and the regulation of the optical and catalytic properties of the hybrid nanostructures, further expanding the application range of the noble metal nanostructures.The results of the study show that the formation of hybrid nanostructures is an effective performance control the way.
