“…In recent years, copper anodization has been carried out using mostly aqueous electrolytes (or even ethylene glycol electrolytes) containing KOH, NaOH, KCl, and NH 4 Cl. 7,[10][11][12] However, none of the investigations have involved the synthesis of novel ethylene glycol based electrolytes with the addition of oxalic acid or NaF as the complexing agent.…”

“…When the Cu foam was anodized at 30 mA cm -2 in a 3 mol L -1 aqueous KOH solution at 40 °C, leaf-like CuO/Cu 2 O nanosheets were obtained directly [105] . Recently, Anantharaj and coworkers found that a much denser Cu(OH) 2 /CuO nanoneedle array could be obtained within just 80 s by the anodization of Cu foil using a conventional three-electrode system-based potentiostatic (at 0.864 V vs. a RHE) method in 1.0 M KOH [106,107] . Increasing the pH of KOH electrolytes led to an increase in the average length of the Cu(OH) 2 /CuO nanoneedles.…”

Nanostructured anodic films on transition metals prepared using the electrochemical anodization method have recently attracted particular attention owing to their extraordinary properties and potential use in a variety of applications. Herein, we provide a thorough review of the anodization fabrication of anodic films with different nanostructures, including nanopores, nanotubes, nanoflowers, nanoneedles and nanowires on transition metals, focusing on the growth processes of nanostructured anodic films on three representative transition metals, namely, iron, copper and zinc. Specific consideration is given to the anodization behavior and formed film nanostructures of these transition metals. We conclude that electrolyte composition plays a key role in influencing the final morphologies of anodic films. Fluoride-containing solutions represent universal electrolytes for forming nanostructured anodic films on transition metals. The main applications of the resulting nanostructured anodic films, especially in energy-related fields, such as photoelectrochemical water splitting and supercapacitors, are also presented and discussed. Finally, we indicate the main challenges associated with the fabrication of anodic films with highly ordered nanostructures and the potential future directions of this field are indicated.

“…Copper anodization is an effective method to synthesize CuO and Cu 2 O film in situ on the copper substrates, which is a common conductor metal used on chips. [13,14] And another advantage of anodization is that the morphology of the film can be regulated easily by changing reaction parameters, such as oxidation potential, concentration and composition of electrolyte solution, temperature, reaction time, etc.…”

Potentiostatic anodization was developed to synthesize copper oxide/copper (CuxO/Cu, x=1,2) electrode with nano structure for sensitive non‐enzymatic glucose detection. At a catalytic potential of 0.55 V, the CuO/Cu electrode presented a high sensitivity of 2954.38 μA mM−1 cm−2 to glucose and a linear range of 0.1 mM to 1.3 mM. The response time is less than 3 s with addition of 0.1 mM glucose. The CuO/Cu electrode above was anodized in 1M KOH solution at −100 mV and the morphology was compact nanoparticles and sparsely dispersed nanosheets, which enlarged the surface area and provided abundant electrocatalytic active sites. Compared the sensing property of electrodes with different morphologies, it indicated that nanostructure was significant to the efficient glucose catalytic oxidation process and it could be regulated by changing the potential and electrolyte concentration during anodization.
