Influence of the electrical parameters on the fabrication of copper nanowires into anodic alumina templates

Electrodeposition of Cu-Ni Alloy Electrodes with Bimodal Porosity and Their Use for Nitrate Reduction

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Among the traditional preparation methods, dealloying is applicable only in a few cases and the final materials contain inclusions of the less noble metal. 1,2 Modern approaches based on electrodeposition within rigid templates 3 -based e.g.…”

“…1,2 Modern approaches based on electrodeposition within rigid templates 3 -based e.g. on polymers, 4,5 silica spheres, 6 alumina membranes 7 -warrant a good control of shape, size and organization of the inner porosity, but require final removal of the template and usually provide uniform tiny porosity that may not improve electrode performances in diffusion controlled processes. 6 A convenient alternative procedure is deposition in presence of copious hydrogen evolution: the gas bubbles act as a dynamic, faint template that disappears after switching off the current and allows a single step preparation.…”

Synthesis and Characterization of Noble Metal Nanowires

“…All the experiments were performed at room temperature. The electrodeposition experiments were performed by pulsed electrodeposition (Inguanta, 2009). Platinum nanowires were growth in aqueous solution of H 2 PtCl 6 5 mM/L and HCl 0.1M by applying a dc current of -0.2 V for 3 s and 0 V for 1 s. In the case of gold nanowires deposition we have used an aqueous solution of HAuCl 4 5 mM/L and H 3 BO 3 0.5 M. The electrodeposion was performed by applying a dc current of -1.3 V for 5 s and 0 V for 1 s The silver nanowires were deposited from an aqueous solution of AgNO 3 30 g/L and H 3 BO 3 45 g/L at -0.7 V for 5 s and 0 V for 1 s. The electrodeposition potential was determined by linear voltammetry.…”

“…Nowadays, the research in the nanomaterials field takes advantage from important funding since they are the basis for the development of new technologies, devices and systems. Bibliographical data present many synthesis methods of simple and/or multilayered nanowires such as: photochemical synthesis (Kim et al, 2002), catalytical synthesis (Huang et al, 2002), vapour-liquid-solid growing (Björk et al, 2002), electrochemical deposition (Yu et al, 1997;Inguanta et al, 2009;Xu & Wang, 2008).…”

Metal Nanowires Subjected to Relavant Hydrated Metal Ions

“…Bibliographical data present many synthesis methods of simple and multilayered nanowires such as: photochemical synthesis [11], catalytical synthesis [12], vapour-liquid-solid growing [13], lithographic patterning [14,15] (are comparatively cumbrous, expensive and not appropriate for large scale fabrication), and template synthesis [16][17][18][19][20] via Electrochemical Deposition (ECD) [21][22][23] in the pores of template. Template based technology is very useful in synthesizing one dimensional nano materials such as nanowires and nanotubes made of metals, semiconductors, polymers and carbon.…”
