A facile solution-phase process has been demonstrated for the selective preparation of single-crystalline Cu nanospindles and microflowers by reducing Cuprous iodide (CuI) with Sodium ascorbate (VCNa) in the presence of Pluronic F-127(F-127) or cetyltrimethylammonium bromide (CTAB). The product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). To study the formation process of Cu nanoparticles, samples obtained at various stages of the growth process were studied by XRD. UV-vis spectra of the Cu nanospindles and microflowers were recorded to investigate their optical properties, which indicated that as-prepared Cu nanostructures exhibited morphology-dependant optical property.

A simple electrodeposition approach has been developed to fabricate Pt and Cu nanostructures via inorganic salt and surfactant to control the shape, size, and distribution of the nanomaterials. The Pt thin film fabricated by cyclic electrodeposition approach reveals low Pt loading amount and high electrocatalytic ability for the reduction reaction of tri-iodide ions indicating a great potential for the application of dye-sensitized solar cell as an efficient counter electrode.

A facile solution-phase process has been demonstrated for the selective preparation of single-crystalline Cu hexagons and flowers by reducing Cuprous iodide (CuI) with Sodium ascorbate (VCNa) in the presence of cetyltrimethyl ammonium chloride (CTAC) or cetyltrimethyl ammonium bromide (CTAB). The product was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM). To study the formation process of Cu nanoparticles, samples obtained at various stages of the growth process were studied by XRD.

Cu Nanostructures

This paper reports a simple and low cost process for the synthesis of various Cu nanostructures by electroless deposition. Oxidation-stable Cu nanoparticles and nanowires were prepared in aqueous solution in the presence of protective agents. When gelatin is used as protective agent, only spherical Cu nanoparticles with a mean diameter in the range of 37 to 44 nm are formed in the solution. Smaller nanoparticles are prepared at a higher concentration of gelatin. When ethylene diamine is used instead of gelatin, one-dimensional growth of Cu nanowires is favored. Varying the amount of EDA and gelatin provides morphological control over the nanostructures.
