Anodic copper oxide nanowire and nanopore arrays with mixed phase content: synthesis, characterization and optical limiting response

Fabrication of superhydrophobic copper metal nanowire surfaces with high thermal conductivity

“…The Cu metal nanowires are successfully developed using simple anodizing and subsequent hydrogen treatment. Anodic Cu(OH)2 and Cu2O nanowires have been reported previously [26,27,34,37]. However, to the best of our knowledge, this is the first successful fabrication of Cu nanowires formed through the reduction of anodic Cu(OH)2 nanowires.…”

“…These surfaces have previously been prepared on Cu using a combination of different processes, such as mechanical grinding, photolithography, electrodeposition, chemical etching/deposition, and chemical oxidation [9-12, 17, 22]. Of these surface micro-/nano-structuring techniques, Cu anodizing in various electrolytes can produce a range of nanostructured surfaces, including nanofibers [8,[23][24][25][26][27], nanotubes [28], nanopores [29], nanoparticles [24], and nanosheets [24,[30][31][32]. Furthermore, anodizing is a facile technique used to form surface morphologies conducive to superhydrophobicity.…”

Effect of morphology on the photoelectrochemical performance of nanostructured Cu2O photocathodes

“…Nevertheless, the capacitance-voltage data using Mott-Schottky equation provide carrier densities under similar experimental conditions unadjusted for surface area, and the carrier density values of the different Cu 2 O morphologies obtained in the experiments are identically affected. Other vital information on the Cu 2 O photocathode properties such as the valence and conduction band edge positions can be calculated from E fb and N A from the equation as follows [101]:…”

Electrodeposition of Cu2O nanostructures with improved semiconductor properties

“…Currently, there are several methods reported in the literature for obtaining Cu 2 O nanostructures, such as thermal oxidation of metallic copper at high temperatures (Rai, 1988), template-assisted growth (Prieto et al, 2003), colloidal methods (Wang et al, 2010) and by electrochemical techniques of anodization or electrodeposition (Kar et al, 2017;Oyarzún et al, 2018). However, high temperature processes generally limit the control of the interfacial characteristics of Cu 2 O thin films, which significantly affects the optical and photoelectrochemical properties of the resulting oxide (Read et al, 2009).…”

“…As an alternative, electrodeposition is a simple, versatile and low-cost method to obtain ordered nanostructures, allowing a better control of their growth (Oyarzún et al, 2018). In this context, the appropriate selection of the chelating or stabilizing agent can promote the growth of diverse morphologies, such as wires, bars, points, pores and tubes, among other nanostructures (Allam and Grimes, 2011;Kar et al, 2017;Read et al, 2009). In particular, the use of lactic acid, tartaric acid, ammonium nitrate, amino acids or polymers as chelating agents or stabilizers, have attracted great attention for different technological applications (Oyarzún et al, 2018;Zoolfakar et al, 2014), due to the improvement that nanostructures present in their physical and optical properties, caused by the incorporation of the chelating agent in the synthesis process .…”
