“…Lead nitrate medium is one of the most fashion media used for PbO 2 electrodeposition. Besides that, lead acetate, 39 lead methyl sulfonate, 40 lead sulfamate, 41 lead fluoroborate 42 and other media have also been reported. In present research, TiO 2 -NTs may be used in Zn electrowinning anode for the first time.…”

“…PAA has found increasing diffusion as a template for nanostructured materials [20,31,41,45,47,48], for applications in microelectronics [49,50], solar cells [30,[51][52][53], filtration [16,54,55], batteries [56][57][58][59], separation of biomolecules [60,61], catalysts [62,63], and other bio-medical sectors [64,65]. The success of PAA as the template is due to its easy dissolution after the filling up of the pores, leading to 1D parallel and perpendicular nanostructures.…”

Anodic Alumina Membranes: From Electrochemical Growth to Use as Template for Fabrication of Nanostructured Electrodes

The great success of anodic alumina membranes is due to their morphological features coupled to both thermal and chemical stability. The electrochemical fabrication allows accurate control of the porous structure: in fact, the membrane morphological characteristics (pore length, pore diameter and cell density) can be controlled by adjusting the anodizing parameters (bath, temperature, voltage and time). This article deals with both the fabrication and use of anodic alumina membranes. In particular, we will show the specific role of the addition of aluminum ions to phosphoric acid-based anodizing solution in modifying the morphology of anodic alumina membranes. Anodic alumina membranes were obtained at −1 °C in aqueous solutions of 0.4 M H3PO4 added with different amounts of Al(OH)3. For sake of completeness, the formation of PAA in pure 0.4 M H3PO4 in otherwise identical conditions was also investigated. We found that the presence of Al(OH)3 in solution highly affects the morphology of the porous layer. In particular, at high Al(OH)3 concentration (close to saturation) more compact porous layers were formed with narrow pores separated by thick oxide. The increase in the electric charge from 20 to 160 C cm−2 also contributes to modifying the morphology of porous oxide. The obtained anodic alumina membranes were used as a template to fabricate a regular array of PdCo alloy nanowires that is a valid alternative to Pt for hydrogen evolution reaction. The PdCo alloy was obtained by electrodeposition and we found that the composition of the nanowires depends on the concentration of two metals in the deposition solution.

“…Introduction: Nanostructured copper materials have attracted much attention because of their good ductility, electrical conductivity and heat conductivity which can be used for various applications such as field emitters [1], current collectors for Li ion batteries [2], electrostatically dissipative devices [3], wire-grid polarisers [4], cooling devices [5] and interconnects [6]. Although several techniques such as photolithography and etching can fabricate these one-dimensional nanostructures, the template-assisted deposition method [7,8] is considered one of the most prominent methods because of the advantages of controllable diameter, high aspect ratio, being economical and large area. In general, anodic aluminium oxide (AAO) films [9,10] and polycarbonate membranes [11,12] were commonly used as templates for manufacturing micronanostructures.…”

Overpotential is widely used in electrodeposition of copper nanowires (Cu NWs). However, the value of >2 is harmful for nanowires formation. In this reported study, pulse technology is used to solve the problem. The authors have investigated the effects of potential and voltage mode on the formation of Cu NWs via a porous anodic aluminium oxide template using the electrochemical deposition method. Cu NWs were synthesised by electrochemical deposition in 0.2 M CuSO 4-based solution under different potential modes of direct current (DC) and pulse. Scanning electron microscopy and grazing incidence X-ray diffraction were used to examine the nanostructure, morphology and phase of Cu NWs. The Cu NWs deposited by pulse mode exhibited a high aspect ratio despite a high potential of 2-3 V, whereas that at higher DC potential was rather short because of hydrogen generation in reduction reaction. The hydrogen byproduct during Cu NWs synthesis can be effectively released at the off period of pulse deposition for good nanowires formation.
