Peculiarities of Bi0 nanowire arrays growth within the alumina template pores by ac electrolysis

Behavior of alumina barrier layer in the supporting electrolytes for deposition of nanowired materials

“…To elucidate the changes taking place inside the barrier layer of porous alumina films during ac treatment in the supporting electrolytes of sulfuric acid, aluminum and magnesium sulfate solutions with the same concentrations and pH as in the metal nws deposition baths [21][22][23][24], the behavior of anodized aluminium electrodes was studied before and after ac treatment in a conventional tetraborate Al anodizing solution under potential sweep mode. As has been shown [25], the set of such votammograms, i a (E a ), makes it possible to separate the processes in the potential domain and, therefore, to follow the changes in potential barriers for alumina to inject and pass the charges through the barrier layer and to grow the oxide film further.…”

Fern-shaped bismuth dendrites electrodeposited at hydrogen evolution potentials

“…19 Also, it is an ideal method for systematically studying the dendritic growth, 20 especially for exploring the morphogenesis under farequilibrium conditions. 21 The electrochemical fabrication of bismuth nanostructures has been realized with the help of templates such as liquid crystal, 3,[22][23][24][25][26][27] anodic alumina membrane, 28,29 etched ion-track polycarbonate membranes. 30 It should be noted that preparing and removing templates are often time-consuming and toilsome processes.…”

The use of transient electrolysis in the technology of oxide composite nanostructured materials: review

“…Under the influence of an alternating current, Jagminas et al [24] precipitated bismuth oxide in the pores of aluminium, the size of its particles being 5 -100 nm. The high-frequency alternating current allowed the impregnation of a nanostructured cadmium selenide (CdSe) in anodic aluminum oxide pores [25].…”
