Effect of the addition of O₂ on copper etching using high density plasma of acetylacetonate/Ar was written by Park, Sung Yong;Lim, Eun Taek;Kim, Seung Hyun;Chung, Chee Won. And the article was included in Materials Science in Semiconductor Processing in 2022.SDS of cas: 20427-59-2 This article mentions the following:

In the present study, the high d. plasma etching of copper thin films masked with SiO₂ was conducted using an acetylacetone/O₂/Ar gas mixture As the concentration of acetylacetone increased, the etch rates for the copper film decreased but the etch selectivity increased. The addition of O₂ gas to the acetylacetone/Ar mixture greatly improved the etch profile without the redeposition on the sidewalls of the copper film. This was attributed to the formation of copper compounds containing oxygen with the assistance of a polymeric protection layer. Good etch profile for the copper film was obtained using an acetylacetone/O₂/Ar gas mixture with a 4:1 vol ratio of acetylacetone to O₂. The proposed acetylacetone/O₂/Ar gas mixture thus represents a potential candidate gas for the dry etching of copper films. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2SDS of cas: 20427-59-2).

Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to low toxicity and inexpensive, earth-abundant.

Needle-like Cu(OH)₂ in situ grown on nanoporous copper ribbon via anodizing route for supercapacitors was written by Gong, Shijie;Liu, Xiaoyang;Yue, Xiang;Zhu, Dongdong;Qi, Jiqiu;Meng, Qingkun;Sui, Yanwei;Zhang, Hao;Zhu, Lei. And the article was included in Materials Chemistry and Physics in 2022.Application In Synthesis of Cuprichydroxide This article mentions the following:

In this paper, Cu-Zr-Ni-Be amorphous alloy was dealloyed to prepare nanoporous coppers (NPCs), which were used as substrate to in situ synthesize needle-like Cu(OH)₂@NPC composites via anodization. Its found that the pore size of NPCs increases with the increase of dealloying time and temperature, and the distribution of pores and ligaments becomes more uniform, which indicates that the structure of NPCs can be adjustable. Cu(OH)₂ nanowires were in situ grown on the surface of NPC substrate through anodization. The growth process of Cu(OH)₂ nanowires is related to the anodization time. As the anodization time increases, the morphol. of Cu(OH)₂ gradually evolves from nanoneedle to nanobeam and finally to nanoflower. Eventually, three-dimensional hierarchical layered porous structure is formed. The formation mechanism of flower-like Cu(OH)₂ is discussed. The needle-like Cu(OH)₂@NPC composite possesses excellent conductivity and high capacity, so it can be used as electrode material for supercapacitors. As the c.d. is 3 mA/cm², the specific capacitance of the composite electrode is 784 mF/cm². The needle-like Cu(OH)₂@NPC composite exhibits 96% of the initial capacitance after 5000 cycles at 10 mA/cm², which shows good cycle stability. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application In Synthesis of Cuprichydroxide).

Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. Copper catalyst has received great attention owing to the low toxicity and low cost.

The development of high-efficiency and economical oxygen reduction reaction (ORR) electrocatalysts is vital for the improvement of renewable energy storage and conversion technol. As a promising energy conversion technol., the performance of microbial fuel cell (MFC) has aroused worldwide interest in recent years owing to its power generation capacity and potential for wastewater treatment. In an aquatic environment, phenanthrene (Phe) is one of the most abundant polycyclic aromatic hydrocarbons. We synthesized a series of CuCo samples successfully via simple in- situ growth and thermal decomposition method. In addition, a single-chamber, air-cathode MFC is investigated for the degradation of phenanthrene in neutral solution The cathode catalyst 1.5 CuCo@NC-800 exhibits a maximum power d. (MPD) of 3248.68 ± 28.21 mW m^-2 in initial cycles and maintained at 95.25% after the Phe degradation And in this study, the reactor with 1.5 CuCo@NC-800 catalyst can effectively reduce Phe at low concentrations and remain above the rate of 98%. Therefore, 1.5 CuCo@NC-800 showed great potential to become a material candidate for non-noble cathode catalyst in MFC.

And the article was included in Ceramics International in 2022.Reference of 20427-59-2 This article mentions the following:

Fabrication of nanostructured electro-active materials with an ordered organization improved the overall performance of supercapacitor devices (SCDs). In this spirit, we developed Cu(OH)₂ nano-flakes that were statistically ordered to resemble flowers. To increase the specific capacitance and kinetics of the electroactive sample, we employed ultra-sonication to fabricate a Cu(OH)₂ nanocomposite with conductive and capacitive carbon nanotubes (CNTs). The textural and functional group analyses of the wet-chem. produced samples were completed using the XRD and FTIR techniques. I-V, FESEM, and EDX measurements Analyses of pure Cu(OH)₂ and its CNT-based nanocomposites were conducted to evaluate the materials’ elec. conductivity, morphol., and chem., resp. The electrochem. characteristics of the as-prepared material’s electrodes were investigated, and the CNT-based nanocomposite electrode demonstrated an outstanding specific capacity (C_sp) and a promising rate of performance. Our CNT-based nanocomposite had a Cs of 733 Fg^-1 at 1 Ag^-1 and dropped 8.7% after 4 x 10³ cycles. The higher electrochem. properties of the nanocomposite are governed by the nano-flakes-like architecture of the Cu (OH)₂ and the more conductive CNT matrix. According to the obtained findings, our manufactured Cu(OH)₂/CNT based electrode has great promise for practical applications in next-generation supercapacitor, which are known to be very efficient. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Reference of 20427-59-2).

The development of highly active single-atom catalysts (SACs) and identifying their intrinsic active sites in oxidizing industrial hazardous hydrocarbons are challenging prospects. Tuning the electronic metal-support interactions (EMSIs) is valid for modulating the catalytic performance of SACs. We propose that the modulation of the EMSIs in a Pt₁-CuO SAC significantly promotes the activity of the catalyst in acetone oxidation The EMSIs promote charge redistribution through the unified Pt-O-Cu moieties, which modulates the d-band structure of at. Pt sites, and strengthens the adsorption and activation of reactants. The pos. charged Pt atoms are superior for activating acetone at low temperatures, and the stretched Cu-O bonds facilitate the activation of lattice oxygen atoms to participate in subsequent oxidation We believe that this work will guide researchers to engineer efficient SACs for application in hydrocarbon oxidation reactions.

Electrocatalytic CO₂ conversion has been considered as a promising way to recycle CO₂ and produce sustainable fuels and chems. However, the efficient and highly selective electrochem. reduction of CO₂ directly into multi-carbon (C₂₊) products remains a great challenge. Herein, we synthesized three type catalysts with different morphologies based on Cu₂O nanowires, and studied their morphol. and crystal facet reconstruction during the pre-reduction process. Benefiting from abundant exposure of Cu (100) crystal facet, the nanosheet structure derived Cu catalyst showed a high faradaic efficiency (FE) of 67.5% for C₂₊ products. Addnl., electrocatalytic CO₂ reduction studies were carried out on Cu(100), Cu(110), and Cu(111) single crystal electrodes, which verified that Cu(100) crystal facets are favorable for the C₂₊ products in electrocatalytic CO₂ reduction Our work showed that catalysts would reconstruct during the CO₂ reduction process and the importance in morphol. and crystal facet control to obtain desired products.

Microfluidics-Assisted Synthesis of Hierarchical Cu₂O Nanocrystal as C₂-Selective CO₂ Reduction Electrocatalyst was written by Jun, Minki;Kwak, Changmo;Lee, Si Young;Joo, Jinwhan;Kim, Ji Min;Im, Do Jin;Cho, Min Kyung;Baik, Hionsuck;Hwang, Yun Jeong;Kim, Heejin;Lee, Kwangyeol. And the article was included in Small Methods in 2022.Safety of Cuprichydroxide This article mentions the following:

Copper-based catalysts have attracted enormous attention due to their high selectivity for C2+ products during the electrochem. reduction of CO₂ (CO2RR). In particular, grain boundaries on the catalysts contribute to the generation of various Cu coordination environments, which have been found essential for C-C coupling. However, smooth-surfaced Cu₂O nanocrystals generally lack the ability for the surface reorganization to form multiple grain boundaries and desired Cu undercoordination sites. Flow chem. armed with the unparalleled ability to mix reaction mixture can achieve a very high concentration of unstable reaction intermediates, which in turn are used up rapidly to lead to kinetics-driven nanocrystal growth. Herein, the synthesis of a unique hierarchical structure of Cu₂O with numerous steps (h-Cu₂O ONS) via flow chem.-assisted modulation of nanocrystal growth kinetics is reported. The surface of h-Cu₂O ONS underwent rapid surface reconstruction under CO₂RR conditions to exhibit multiple heterointerfaces between Cu₂O and Cu phases, setting the preferable condition to facilitate C-C bond formation. Notably, the h-Cu₂O ONS obtained the increased C₂H₄ Faradaic efficiency from 31.9% to 43.5% during electrocatalysis concurrent with the morphol. reorganization, showing the role of the stepped surface. Also, the h-Cu₂O ONS demonstrated a 3.8-fold higher ethylene production rate as compared to the Cu₂O nanocube. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Safety of Cuprichydroxide).

And the article was included in Inorganic Chemistry Communications in 2022.Quality Control of Cuprichydroxide This article mentions the following:

In this study, nanoscale zero-valent iron-carbon materials based on the oil refining byproducts (nZVI-SBE@C) were prepared through anoxic pyrolysis and liquid phase reduction method, and its ability to remove Pb(II) from aqueous solution was tested for the first time. In preparation process, when the mass ratio of C/Fe is 1:2, nZVI-SBE@C has the maximum removal capacity of Pb(II) (182.29 mg/g), which is four times that of SBE@C (51.37 mg/g). In the research of Pb(II) removal behavior, adsorption process by nZVI-SBE@C was fitted well with Langmuir isotherm model and pseudo-second-order kinetic model, and the Langmuir monolayer maximum adsorption capacity of nZVI-SBE@C for Pb(II) was 223.52 mg/g. In the N2 and air initial atm., Pb(II) removal reached 95.37% and 42.37%, resp., which were higher than that in blank control group (24.44%). The promotion order of the coexisting cations for nZVI-SBE@C to remove Pb(II) is: Na⁺ > K⁺ > Mg²⁺ (the effect of NO^–₃), and the inhibition order is: Cu²⁺ < Fe³⁺ < Al³⁺ (the effect of the solubility products of precipitation as well as ionic radius). Pb(II) removal by nZVI-SBE@C increased with the increase of initial solution pH (2.30-5.80). Though the characterization of the materials before and after the reaction, meanwhile combining with exptl. data, Pb(II) removal mechanisms of nZVI-SBE@C may include surface adsorption, electrostatic attraction, ion exchange, surface complexation and nZVI reduction (small portion).

Helical copper-porphyrinic framework nanoarrays for highly efficient CO₂ electroreduction was written by Xiao, Yi-Hong;Zhang, Yu-Xiang;Zhai, Rui;Gu, Zhi-Gang;Zhang, Jian. And the article was included in Science China Materials in 2022.Application In Synthesis of Cuprichydroxide This article mentions the following:

In recent years, metal-organic frameworks (MOFs) have been extensively investigated as electrocatalysts due to their highly efficient electroreduction of CO2. Herein, the electrocatalytic CO₂ reduction reaction was investigated by growing helical Cu-porphyrinic MOF Cu meso-tetra(4-carboxyphenyl)porphyrin (TCPP) on Cu(OH)₂ nanoarrays (H-CuTCPP@Cu(OH)₂) using a sacrificial template method. The electrocatalytic results showed that the H-CuTCPP@Cu(OH)₂ nanoarrays exhibited a high acetic acid Faradaic efficiency (FE) of 26.1% at -1.6 V vs. Ag/Ag⁺, which is much higher than the value of 19.8% obtained for non-helical CuTCPP@Cu(OH)₂ (nH-CuTCPP@Cu(OH)₂). The higher efficiency may be because space was more effectively utilized in the helical MOF nanoarrays, resulting in a greater number of active catalytic sites. Furthermore, in situ diffuse reflectance IR Fourier transform spectra showed that the H-CuTCPP@Cu(OH)₂ nanoarrays have much stronger CO linear adsorption, indicating a better selectivity of acetic acid than that of nH-CuTCPP@Cu(OH)₂. In this study, we develop new helical nanomaterials and propose a new route to enhance the reduction of CO₂. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application In Synthesis of Cuprichydroxide).
