Additive influence on Cu nanotube electrodeposition in anodised aluminium oxide templates

Fabrication of Vertically aligned Copper Nanotubes as a Novel Electrode for Enzymatic Biofuel Cells

“…The AAO template was subsequently etched with 6 M NaOH solution to get free standing CuNTs. The trace of remaining NaOH was removed by gently rinsing with deionized water and then the samples were dried in vacuum at 60 º C [19]. The length of copper nanotube was determined by strength of current and deposition time whereas thickness is determined by pore size of template [20].…”

Electrochemical synthesis and magnetism of magnetic nanotubes

“…Therefore, when electrodepositing inside the pores, the reduction of the metal ions will preferentially occur on the top end of the annular electrode. However, some authors state that the metallic contact at the bottom of the pores can be a flat film and does not necessarily need to have an annular shape (Graham et al, 2014;Li et al, 2009a;Ponrouch et al, 2010a;Chowdhury et al, 2009). Consequently, without the assistance of an annular base electrode, the formation of nanotubular shaped structures inside nanopores would be harder to achieve (Liu et al, 2008a;Cheng et al, 2008;Arshad et al, 2014;Atalay et al, 2010;Xu et al, 2012).…”

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

“…According to these authors, free-standing Cu NWs (aspect ratio [17][18][19][20] can be obtained in alkaline electrolyte, whilst NWs electrodeposited in very acid electrolyte showed the worst uniformity. Liu et al [28], found that both morphology and crystalline structure of Cu NWs were influenced by the deposition potential.…”

“…This has been possible, thank to a better control in the electrodeposition process of metallic Cu; with this aim, optimization of bath composition was investigated, in order both to increase its throwing power and to obtain very uniform thickness of the metallic deposit [15,16]. The effect of various additives (such as polyethylene glycol) on the morphological aspects of nanostructures and on the growth kinetics was investigated and it was showed that growth of Cu wires or nanotubes is significantly influenced by their action [17].…”
