Electrochemical production of cuprous oxide using the anode-support system

The manufacture of porous cuprous oxide film with photocatalytic properties via an electrochemical–chemical combination method

“…Anodization is a common route to prepare cupric oxide and cuprous oxide particles due to its easy accessibility, low-cost, high productivity and good controllability. [12][13][14][15][16] However, reports of preparing Cu 2 O films directly via anodization are quite rare, because the basic conditions to fabricate pure Cu 2 O, such as high electrolyte concentration, alkaline environment and large current density, always result in particles rather than films. According to W. C. Cooper and J. Ji, 12 the hydrolysis reaction (eqn (1)) is the key step in the electrode reaction, which would result in the product flaking from the substrate and accumulating on the bottom of the electrolytic cell.…”

Synthesis and Biomedical Applications of Copper Oxide Nanoparticles: An Expanding Horizon

“…62 The ideal process in electrochemical synthesis is the anodic dissolution of copper in an alkaline solution. 63 It involves the electrolysis of a copper material such as copper plate or foil in a two-electrode electrochemical cell containing a supporting electrolyte at varying potentials for different time periods. A typical reaction is as follows: 58 Anode (3)…”

Preparation of Cu2O nanoparticles in cupric chloride solutions with a simple mechanochemical approach

“…In recent years, it is particularly applied as the photocatalyst for overall water splitting under visible light irradiation, photo electron transition material and cathode material of lithium ion cell [3][4][5]. Thus, more and more research interest has been paid to the preparation and application of the Cu 2 O nanoparticles.…”

“…Cl − ] concentration is 0.75 × 10 −2 mol/L because the Cu 2 (OH)3 Cl phase could not be found in the XRD patterns. Thus, it can be deduced that different [Cl − ] concentration would affect reactions during different milling periods, e.g., the reaction time for forming single phase Cu 2 O and the size as well as shape of Cu 2 O nanoparticles.…”
