Electrodeposition and electrocatalytic activity of Cu2O film on stainless steel substrate

Electrodeposition of Cu2O nanostructures with improved semiconductor properties

“…The values obtained for this material are much lower than those previously reported for various types of Cu 2 O nanostructures obtained by electrodeposition (1.92-2.47 eV), using various substrates, chelating agents and chemical composition of the electrolytic solution (see Table 1). This corroborates that the use of soluble polymeric materials have not been previously studied to stabilize the electrodeposition reaction of Cu 2 O nanostructures, besides that in these conditions the semiconductor properties of Cu 2 O nanostructures are considerably benefited, generating a material with potential applications (Ait et al, 2020;Anastasiadou et al, 2019;Anower et al, 2017;Bao et al, 2012;Das et al, 2018;Gu Kim et al, 2014;Lee et al, 2004;Y. Liu et al, 2016;R.…”

“…Therefore, it is expected that in similar way the polymer p(NVP-co-AI) coordinates the metal Cu +2 in solution during the electrodeposition process, being the stabilizing agent of this reaction . Precisely the use of a water-soluble polymeric material as chelating agent during the electrodeposition of Cu 2 O nanostructures has not been previously reported in scientific literature (Ait et al, 2020;Anastasiadou et al, 2019;Anower et al, 2017;Bao et al, 2012;Das et al, 2018;Gu et al, 2010;Kim et al, 2014;Lee et al, 2004;Y. Liu et al, 2016;R.…”

The influence of polarity of electrodeposited Cu2O thin films on the photoelectrochemical performance

“…In an alkaline solution, it is the CuL 2 2¹ and [CuL 2 (OH)] 3¹ complexes shown in reaction (1) that are the most likely to form. 20,21) The cupric lactate complexes in the diffusion layer are then reduced to Cu 2 O [reactions (2) and (3)], thereby causing the L 2¹ ions to be separated [reaction (4)]. Thus, cupric lactate complexes can be reduced to Cu 2 O by a limited reduction of Cu 2+ to Cu + due to the low solubility of monovalent copper in water.…”

Cu2O‐Based Nanocomposites for Environmental Protection

“…The electron-hole pair is formed when photon energies This mechanism for copper toxicity implies the capacity of CuO to generate reactive oxygen species (ROS) involving Cu ions via Fenton-like reactions through the Haber-Weiss cycle. It is worth noting that Fenton-like Cu + /Cu 2+ reactions can also take place in the absence of irradiation [190,191]. It is worth noting that Fenton-like Cu + /Cu 2+ reactions can also take place in the absence of irradiation [190,191].…”
