Copper Acetate for In-Situ Preparation of Flower-Like Open-Structured Polycrystalline Copper

Zhao, Yaling, et al. Nano Energy 97 (2022): 107124.

This work develops flower-like open-structured polycrystalline copper (FOSP-Cu) supported on carbon paper.
In-Situ Preparation of FOSP-Cu
Carbon fiber paper was cut into small pieces (1.0 cm × 0.5 cm) and heated with an alcohol lamp for 30 seconds to achieve good hydrophilicity. FOSP-Cu supported on carbon fiber paper was prepared by electrodeposition in copper acetate solutions of different concentrations, containing 0.12 M H₂SO₄. The deposition potential scan range was -0.15 to +0.20 V vs. Ag/AgCl, with a scan rate of 200 mV s⁻¹ and 60 deposition cycles. Pt plates (1 cm²) and Ag/AgCl (filled with saturated KCl) were used as the counter electrode and reference electrode, respectively. By changing the concentration of copper acetate while keeping other parameters constant, FOSP-Cu-X (X = 0.01, 0.05, 0.1, and 0.2) samples were obtained, where X represents the concentration of copper acetate during the electrodeposition process. For comparison, a sample (denoted as FOSP-Cu-0.1 (unburned)) was prepared through the copper electrodeposition process on carbon paper without the rapid burning process.

Copper Acetate Modification of Anatase Phase Titanium Dioxide Nanotubes (ATNT)

Jabeen, Saadia, et al. Applied Nanoscience 11 (2021): 79-90.

Copper oxide was deposited onto titanium dioxide nanotubes using a dip-coating process. For this, a 0.1 M copper acetate solution and a 0.1 M NaOH solution were prepared in deionized water. The anatase nanotubes were then immersed in the copper acetate solution for 1 minute, rinsed with deionized water, and subsequently immersed in the NaOH solution for 1 minute, followed by rinsing with deionized water. This process was repeated ten times. After dip-coating, the samples were annealed at 400°C for 2 hours to convert the copper hydroxide to CuO.
For the electrodeposition of CuO, a 0.1 M copper acetate solution was prepared in deionized water. A two-electrode system was used, with the titanium dioxide nanotube film as the working electrode and a graphite rod as the counter electrode. The electrodeposition was carried out at 0.7 V, 0.9 V, and 1.1 V for 100 seconds using a Gamry potentiostat.

Electrochemical Deposition of Cu₂O/Graphene Nanoplatelet Composites Using Copper Acetate and Graphite Rods

Kumar, J. Sharath, et al. New Journal of Chemistry 42.5 (2018): 3574-3581.

An optimized two-step electrochemical deposition technique is presented for synthesizing Cu₂O/graphene nanoplatelet (GNP) composites using copper acetate and graphite rods. In the first step, graphene nanosheets are electrodeposited from the graphite rod onto a stainless steel substrate, followed by the second step where Cu₂O nanoparticles (NPs) are electrodeposited from a copper acetate solution onto the same electrode.
Preparation of Cu₂O-Graphene Nanoplatelet Composite
As shown in the figure, Cu₂O-graphene nanoplatelet (GNP) composites (CGNP) are prepared using a two-step electrochemical deposition method. After a series of controlled experiments, the applied potential and deposition duration were optimized. In brief, a stainless steel (SS) strip measuring 5 x 1 cm² was ultrasonically cleaned in a 5% HCl solution to serve as the substrate electrode for electrodeposition. In a beaker containing 1 M NaOH as the electrolyte, a graphite rod was used as the cathode and the SS strip as the anode. Electrochemical deposition was carried out at 20 V and 6.0 A for approximately 60 minutes, during which GNPs were deposited onto the SS strip. The SS strip with deposited GNPs was then immersed in another beaker containing 0.05 M Cu(CH₃COOH)₂, with a clean SS strip as the anode, and electroplated at 3.5 V and 0.05 A for 30 seconds. In the second step, Cu²⁺ ions were adsorbed onto the pre-deposited GNPs, followed by calcination at 200°C under a nitrogen atmosphere.
Using a similar procedure, SS strips with only Cu₂O (CNP) deposition and only GNP deposition were prepared. For the preparation of GNP, only the first electrochemical deposition step was performed for about 60 minutes. For the synthesis of CNP, only the second electrochemical deposition step was carried out for approximately 2 minutes. The inset images show digital photos of the SS substrate, SS with GNP deposition, and SS with CGNP deposition.
