Morphological structure at the nanoscale dictates material properties due to size and shape dependent effects which are not present in bulk materials. In this work, novel synthetic routes are presented for the synthesis of copper nanoparticles including cubes, octahedra and platelets which could find applications in catalysis and sensing applications. In addition, intermediate morphology of copper/cuprous oxide nanoparticles during reduction by hydrogen gas are characterized by UV-Vis spectroscopy and TEM imaging. The results of the UV-Vis characterization show that nanoparticle oxide reduction occurs by a different mechanism than reduction in the bulk due to short diffusion lengths and high metal diffusivity. The results of this work may be applied to the fields of catalysis, sensing, plasmonics, and spectroscopy where improved control of structure at the atomic level leads to improved functionality.
