The ability to synthesize metal nanoparticles with uniform sizes and shapes is of the utmost importance in creating new materials with applications in catalysis, sensors, electronics, and many other cutting edge technologies. Copper nanoparticles have gained attention because of their potentially useful electronic properties at the nanoscale, as well as their low cost when compared with other metals such as silver, gold, and platinum nanoparticles. However, partially due to their propensity for oxidation, there are several challenges to synthesizing uniform, shaped copper nanoparticles of sufficient stability. This presentation focuses on a new strategy to synthesize shaped, mono-dispersed copper particles of various sizes. We have developed a bottom-up route, involving the control of molecular encapsulation, to synthesize particles of various shapes, including nanorods, cubes, pyramids, and spheres. The particles are stable when dispersed in organic solvent and are resistant to oxidation. The parameters necessary to engineer the sizes, shapes, surface properties, and some potential applications will be discussed in this presentation.
