Synthesis and characterization of hollow gold tetrapods

摘要

The development of different morphologies is desired in the field of nano-materials research. Gold is an interesting material for electronic nanodevice among many other potential applications and lots of morphologies have been prepared. However, hollow gold tetrapod has not been reported. In this paper, hollow gold tetrapods were prepared for the first time by using ZnO tetrapods as a template, HAuCU as a gold source and ascorbic acid as a reducing reagent. The structure and growth mechanism were investigated and the results show that the hollow gold tetrapods are composed of gold nanoparticles with a mean diameter of about 7.0 nm.
