Electrochem. reduction of CO₂ comprising the CO₂ reduction reaction (CO₂RR) and O evolution reaction (OER) is one of the most promising technologies for electrification of the chem. process industry. Here, the performance of a electrocatalyst with a three-dimensional structure of InZnCu on Cu foam (CF) is presented. This electrocatalyst was fabricated by electrodeposition of In and Zn over Cu and exhibited a superior reduction of CO₂ to CO at a faradaic efficiency of 93.7% at -0.7 V and an excellently long duration of 100 h. Due to the synergy of the thin In layer, the Zn nanosheets provided a high surface-active area and strong mech. robustness during the reaction. Addnl., a two-electrode system was constructed based on the CF-modified surface, which provided valuable guidelines on the overall CO₂RR-OER system for further evolution. Also, due to the facile synthesis, the bimetal-layer double hydroxide (LDH) exhibited high conductivity and high OER performance. Hence, the two-electrode system assembled excellent electrocatalysts for the CO₂RR-OER (InZnCu/CF||Cu(OH)₂ NWs@NiCo-LDH/CF) with high conversions of CO₂ to CO of 67% and 88% at 2 and 50 mA cm^-2, resp. Notably, the CO₂RR-OER system exhibited excellent stability in a 40 h CO₂ conversion with a constant c.d. of 2 mA cm^-2 at an ultralow voltage of 1.59 V. Also, the calculation of the energy input converting CO per ton of CO₂ resulted in a low energy input range for further development in scalability. This overall CO₂RR-OER proposes development in electrochem. CO₂ reduction for industrial applications. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Formula: CuH2O2).

And the article was included in Sensors and Actuators, B: Chemical in 2022.Computed Properties of CuH2O2 This article mentions the following:

High-performance semiconductor gas sensors comprising of metal oxides have offered appealing promise to environment monitor devices but remain challenging due to their high working temperature and sluggish response/recovery speed. Here we report a simple impregnation method that utilizing the high catalytic activity of palladium oxide activates copper oxide parallel nanowires assembled hierarchical microspheres (PdO-CuO NWMs). And then gas-sensing devices with different decorating concentrations were fabricated to investigate their sensing performance on hydrogen sulfide (H₂S). It was demonstrated that the CuO microspheres with 2 wt% PdO decorating concentration is the optimum, with high response of 6.8 and extremely short response/recovery time of 1.8/4.1 s towards 50 ppm H₂S at 30°C, effective enhancing the response (4.9-50 ppm H₂S) and working temperature (150°C) of pristine CuO NWMs sensor. The boosting sensing performance of our PdO-CuO NWMs gas sensor was attributed to the synergistic effect of high catalytic noble nanoparticles and hierarchical structures. The coupling strategy offers new insights to explore room temperature and real-time monitoring gas sensors.

Development of an under-liquid super-repellent (ULSR) surface that can act as a versatile platform for separating both liquid/liquid and liquid/gas mixtures is highly desirable, yet still hard to realize. Herein, to address this challenge, a Cu(OH)₂ nanowire textured surface on copper mesh was developed through a simple immersion process. The resulting Cu(OH)₂ nanowire surface displayed underwater superoleophobicity, underoil superhydrophobicity, and unusual dual superoleophobicity under immiscible oil-oil system. Exploiting its superlyophobicity under-liquid, the Cu(OH)₂ nanowire covered copper mesh was applied to sep. oil/water mixtures, emulsions, and oil/oil mixtures effectively, even though the surface tension between two liquids was just 2.4 mN/m. The separation efficiency is higher than 99% for all mixtures, and the oil/water separation efficiency can maintain above 98% even after 40 cycles. Furthermore, owing to its superaerophobicity underwater and underoil, the obtained copper mesh was also able to sep. gas from bulk water and oil efficiently. This work is hoped to provide a key addition to the fields of ULSR surfaces as well as membrane-based separation techniques.

Electrochem. reduction of CO₂ to multi-carbon fuels and chem. feedstocks is an appealing approach to mitigate excessive CO₂ emissions. However, the reported catalysts always show either a low Faradaic efficiency of the C₂₊ product or poor long-term stability. Herein, we report a facile and scalable anodic corrosion method to synthesize oxygen-rich ultrathin CuO nanoplate arrays, which form Cu/Cu₂O heterogeneous interfaces through self-evolution during electrocatalysis. The catalyst exhibits a high C₂H₄ Faradaic efficiency of 84.5%, stable electrolysis for âˆ?5 h in a flow cell using a neutral KCl electrolyte, and a full-cell ethylene energy efficiency of 27.6% at 200 mA cm^-2 in a membrane electrode assembly electrolyzer.

Oriented construction Cu₃P and Ni₂P heterojunction to boost overall water splitting was written by Liu, Huibing;Gao, Jing;Xu, Xinchen;Jia, Qiaohuan;Yang, Liu;Wang, Shitao;Cao, Dapeng. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2022.Application In Synthesis of Cuprichydroxide This article mentions the following:

Development of efficient and earth-abundant bifunctional catalysts towards oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is imperative to overall water splitting. Herein, in-situ vertically grown bimetallic phosphide nanosheets containing abundant Cu₃P/Ni₂P heterogeneous interfaces are successfully synthesized on Cu foam (marked as Cu₃P/Ni₂P@CF) as the bifunctional electrocatalyst for both HER and OER. Owing to the synergistic effects of electronic regulation of heterojunction and the hierarchical array structure on 3D substrate, the Cu₃P/Ni₂P@CF integrated electrode displays the overpotential of 330 mV @ 50 mA cm^-2 for OER and 88.1 mV @ 10 mA cm^-2 for HER in 1 M KOH. Interestingly, the catalyst -based water electrolyzer only demands a low cell voltage of 1.56 V@10 mA cm^-2, exceeding the integrated Pt/C + IrO₂ counterpart. D. functional theory (DFT) results further disclose that the charge rearrangement of heterogeneous interface can not only endow the hydrogen binding energy (ΔG*H) approach to zero, but also boost the H₂O dissociation and *OH desorption via multi-site synergy for HER. This work provides a valuable approach to construct advanced materials towards overall water splitting.

Synergistic nanowire-enhanced electroporation and electrochlorination for highly efficient water disinfection was written by Huo, Zheng-Yang;Winter, Lea R.;Wang, Xiao-Xiong;Du, Ye;Wu, Yin-Hu;Hubner, Uwe;Hu, Hong-Ying;Elimelech, Menachem. And the article was included in Environmental Science & Technology in 2022.COA of Formula: CuH2O2 This article mentions the following:

Conventional water disinfection methods such as chlorination typically involve the generation of harmful disinfection byproducts and intensive chem. consumption. Emerging electroporation disinfection techniques using nanowire-enhanced local elec. fields inactivate microbes by damaging their outer structures without byproduct formation or chem. dosing. However, this phys.-based method suffers from a limited inactivation efficiency under high water flux due to an insufficient contact time. Herein, we integrate electrochlorination with nanowire-enhanced electroporation to achieve a synergistic flow-through process for efficient water disinfection targeting bacteria and viruses. Electroporation at the cathode induces sub-lethal damages on the microbial outer structures. Subsequently, electrogenerated active chlorine at the anode aggravates these electroporation-induced injuries to the level of lethal damage. This sequential flow-through disinfection system achieves complete disinfection (>6.0-log) under a very high water flux of 2.4 x 10⁴ L/(m² h) with an applied voltage of 2.0 V. This disinfection efficiency is 8 times faster than that of electroporation alone. Further, the specific energy consumption for the disinfection by this novel process is extremely low (8 x 10^-4 kW h/m³). Our results demonstrate a promising method for rapid and energy-efficient water disinfection by coupling electroporation with electrochlorination to meet vital needs for pathogen elimination. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).

Modification of a Cu Mesh with Nanowires and Magnesiophilic Ag Sites to Induce Uniform Magnesium Deposition was written by Wang, Fei;Wu, Dongzheng;Zhuang, Yichao;Li, Jialin;Nie, Xianzhen;Zeng, Jing;Zhao, Jinbao. And the article was included in ACS Applied Materials & Interfaces in 2022.Name: Cuprichydroxide This article mentions the following:

The nature of dendrite-free magnesium (Mg) metal anodes is an important advantage in rechargeable magnesium batteries (RMBs). However, this traditional cognition needs to be reconsidered due to inhomogeneous Mg deposits under extreme electrochem. conditions. Herein, we report a three-dimensional (3D) Cu-based host with magnesiophilic Ag sites (denoted as “Ag@3D Cu mesh”) to regulate Mg deposition behaviors and achieve uniform Mg electrodeposition. Mg deposition/stripping behaviors are obviously improved under the cooperative effect of nanowire structures and Ag sites. The test results indicate that nucleation overpotentials are reduced distinctly and cycling performances are prolonged, suggesting that the general rules of 3D structures and affinity sites improve the durability and reversibility of Mg deposition/stripping. Besides, a unique concave surface structure can induce Mg to deposit into the interior of the interspace, which utilizes Mg more efficiently and leads to improved electrochem. performances with limited Mg content. Furthermore, in situ optical microscopic images show that the Ag@3D Cu mesh can attain a smooth surface, nearly without Mg protrusions, under 8.0 mA cm-2, which prevents premature short circuits. This report is a pioneering work to demonstrate the feasibility of modification of Cu-based current collectors and the necessity of functional current collectors to improve the possibility of practical applications for RMBs.

Electrochemical Stability of Zinc and Copper Surfaces in Protic Ionic Liquids was written by Greaves, Tamar L.;Dharmadana, Durga;Yalcin, Dilek;Clarke-Hannaford, Jonathan;Christofferson, Andrew J.;Murdoch, Billy J.;Han, Qi;Brown, Stuart J.;Weber, Cameron C.;Spencer, Michelle J. S.;McConville, Chris F.;Drummond, Calum J.;Jones, Lathe A.. And the article was included in Langmuir in 2022.Application of 20427-59-2 This article mentions the following:

Ionic liquids are versatile solvents that can be tailored through modification of the cation and anion species. Relatively little is known about the corrosive properties of protic ionic liquids In this study, we have explored the corrosion of both zinc and copper within a series of protic ionic liquids consisting of alkylammonium or alkanolammonium cations paired with nitrate or carboxylate anions along with three aprotic imidazolium ionic liquids for comparison. Electrochem. studies revealed that the presence of either carboxylate anions or alkanolammonium cations tend to induce a cathodic shift in the corrosion potential. The effect in copper was similar in magnitude for both cations and anions, while the anion effect was slightly more pronounced than that of the cation in the case of zinc. For copper, the presence of carboxylate anions or alkanolammonium cations led to a notable decrease in corrosion current, whereas an increase was typically observed for zinc. The ionic liquid-metal surface interactions were further explored for select protic ionic liquids on copper using XPS and SEM (SEM) to characterize the interface. From these studies, the oxide species formed on the surface were identified, and copper speciation at the surface linked to ionic liquid and potential dependent surface passivation. D. functional theory and ab initio mol. dynamics simulations revealed that the ethanolammonium cation was more strongly bound to the copper surface than the ethylammonium counterpart. In addition, the nitrate anion was more tightly bound than the formate anion. These likely lead to competing effects on the process of corrosion: the tightly bound cations act as a source of passivation, whereas the tightly bound anions facilitate the electrodissolution of the copper. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Application of 20427-59-2).

Nanofluid has gained vast attention as a novel heat transfer working fluid owing to its superiority in thermal conductivity and rheol. properties. Meanwhile, the liquid range and the stability of nanofluids are of great significance since it dominates the utilization scope of a working fluid. In this work, with the aim at solving the poor stability associated with short liquid range of traditional nanofluids, a novel “one-step” preparation protocol was developed using Cu(OH)₂ as a precursor and deep eutectic solvents (DESs) as dispersing medium. The as-prepared nanofluid bears an extraordinary static stability that can be kept for at least two months without observation of any sedimentation thanks to the in-situ formed Cu₂O nanoparticle in DESs under a microwave irradiation condition and wide liquid range attributed to the low saturated pressure of DESs. Structural anal., such as SEM, TEM, XRD, XPS and FTIR anal., and thermophys. properties of the nanofluids were subject to a comprehensive study. Thermal conductivity anal. indicated that the presence of Cu₂O nanoparticle slightly impacts the thermal conductivity when the mass fraction of the nanoparticle is small. Notably, this DESs based nanofluid features promising photothermal conversion that can reach 83.74% with the addition of 0.1 wt% Cu₂O nanoparticle. This study provides an important avenue for the preparation of nanofluids with high static stability. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Safety of Cuprichydroxide).
