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. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Computed Properties of CuH2O2).

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.

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.

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.

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).

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 recent years, kitchen oily wastewater has received much attention because of its harmful effects on the ecol. environment. Therefore, separation of oil from kitchen oily wastewater has become an urgent issue. In this study, this problem could be solved using polyester fabrics covered with cupric hydroxide and cellulose. The functional fabric was obtained by the dipping-rolling-drying process which is an easy and practical way to prepare the fabric and could improve the hydrophilicity of polyester. The functional polyester fabric could sep. oil/water mixtures completely under the force of gravity with a high water flux of 2079 L m-2 h-1-3620 L m-2 h-1 and high separation efficiency of 99.6%. Because kitchen oily wastewater contains floating oil and emulsified oil, we also tested the separation of oil-in-water emulsions. The functional polyester fabric could successfully sep. the emulsions with the water flux of 1210 L m-2 h-1-2018 L m-2 h-1 and a separation efficiency of 99.0%. Moreover, the water flux and separation efficiency of functional polyester fabric remained unchanged after the immersion in salt, alkali, and acid solutions, indicating that the functional polyester fabric exhibited commendable environmental stability. The oil in Chongqing Street Noodles soup with a high oil content was separated to simulate real-life oil/water separation, confirming that the functional polyester fabric could be applied to the treatment of kitchen oily wastewater.

Activating copper oxide for stable electrocatalytic ammonia oxidation reaction via in-situ introducing oxygen vacancies was written by Huang, Jingjing;Chen, Zhe;Cai, Jinmeng;Jin, Yongzhen;Wang, Tao;Wang, Jianhui. And the article was included in Nano Research in 2022.Application In Synthesis of Cuprichydroxide This article mentions the following:

Electrocatalytic ammonia oxidation reaction (EAOR) provides an ideal solution for on-board hydrogen supply for fuel cells, while the lack of efficient and durable EAOR catalysts has been a long-standing obstacle for its practical application. Herein, we reported that the defect engineering via in-situ electrochem. introducing oxygen vacancies (Vo) not only turns the inactive CuO into efficient EAOR catalyst but also achieves a high stability of over 400 h at a high c.d. of ∼ 200 mA·cm^-2. Theor. simulation reveals that the presence of Vo on the CuO surface induces a remarkable upshift of the d-band center of active Cu site closer to the Fermi level, which significantly stabilizes the reaction intermediates (NHx) and efficiently oxidizes NH₃ into N₂. This Vo-modulated CuO shows a different catalytic mechanism from that on the conventional Pt-based catalysts, paving a new avenue to develop inexpensive, efficient, and robust catalysts, not limited to EAOR.

Metallic foams, especially copper foams (CF), have been investigated to solve the problems of leaking and low thermal conductivity of phase change materials (PCMs), which helps to promote the application in solar thermal energy storage and thermal management. In this paper, the surface and pore structure of com. CF was modified by in-situ formed copper nanowires and the introduction of flake graphite (FG). The copper nanowires and embedded FG not only provide greater capillary absorption force to prevent the leakage of liquid paraffin but also enhance the thermally conductive and photothermal conversion efficiency of the phase change composites. The thermal conductivity of the modified CF supported composite PCM reaches 4.1 W m^-1 k^-1, which is 1.6 times of the un-modified CF supported composite PCM and 20.5 times of paraffin. These results indicate the great application prospects in the fields of solar thermal energy storage and thermal management.

Stable Li/Cu₂O composite anodes enabled by a 3D conductive skeleton with lithiophilic nanowire arrays was written by Zhang, Nanxiang;Zhao, Teng;Wei, Lei;Feng, Tao;Wu, Feng;Chen, Renjie. And the article was included in Journal of Power Sources in 2022.HPLC of Formula: 20427-59-2 This article mentions the following:

Lithium (Li) metal is an attractive anode for next-generation high-energy-d. rechargeable batteries due to its high theor. capacity and low redox potential. However, the uncontrolled growth of Li dendrites and infinite volume change during Li stripping/plating process lead to low coulombic efficiency and safety concern. To solve these critical issues, copper foam with Cu₂O nanowire arrays (COCF) is rationally designed and used as three-dimensional (3D) conductive skeleton for compositing Li. Cu₂O nanowire arrays structure with strong capillary forces and lithiophilicity is beneficial for the wetting of molten Li on surface and Li ⁺ nucleation. In addition, the 3D robust Cu skeleton with porous structure can reduce the local c.d. and regulate the distribution of Li⁺ flux on the electrode surface, leading to homogeneous nucleation and deposition of lithium, as well as mitigating the volume expansion. As a result, the COCF-Li composite lithium anode exhibits a prolonged cycling stability over 1000 h with a low over-potential of ∼50 mV at a c.d. of 1 mA•cm^-2 in a sym. cell. Even at a c.d. of 4 mA•cm^-2 and deposition capacity of 4 mAh•cm^-2, it still delivers a stable cycling performance for 600 h.
