Abstract

We review recent developments in our group regarding the solution-phase synthesis of one-dimensional nanostructures of metals. The synthetic approaches include solution-liquid-solid growth for nanowires of low-melting-point metals such as Pb; seed-directed growth for Ag nanowires, nanobeams, and nanobelts; kinetically controlled growth for Pt nanorods, nanowires, and multipods; and galvanic replacement for nanotubes of Au, Pt, and Pd. Both characterization and mechanistic studies are presented for each nanostructure. Finally, we highlight the electrical and plasmonic properties of these metal nanostructures and discuss their potential applications in nanoscale devices.

摘要

我们回顾了我们小组在金属一维纳米结构溶液相合成方面的最新进展。合成方法包括低熔点金属（如铅）纳米线的溶液-液-固生长；银纳米线、纳米梁和纳米带的种子导向生长；铂纳米棒、纳米线和多足体的动力学控制生长；以及金、铂和钯纳米管的电化学生长置换。对每种纳米结构都进行了表征和机理研究。最后，我们强调了这些金属纳米结构的电学和等离子体特性，并讨论了它们在纳米级器件中的潜在应用。
