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. Mechanism analyzes reveal that the stable nanostructures, stable Cu/Cu₂O interfaces, and enhanced adsorption of the *OCCOH intermediate preserve selective and prolonged C₂H₄ production The robust and scalable produced catalyst coupled with mild electrolytic conditions facilitates the practical application of electrochem.

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. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Electric Literature of 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.

Improving the cycling stability of lithium metal anodes using Cu₃N-modified Cu foil as a current collector was written by Tang, Danlei;Yuan, Lixia;Liao, Yaqi;Jin, Wenxuan;Chen, Jie;Cheng, Zexiao;Li, Xiang;He, Bin;Li, Zhen;Huang, Yunhui. And the article was included in Science China Materials in 2022.COA of Formula: CuH2O2 This article mentions the following:

Lithium (Li) metal anodes have the potential to stimulate the development of secondary batteries due to their high theor. specific capacities and low redox potentials among all possible solid secondary anode compounds However, the growth of Li dendrites during repeated Li stripping/plating processes leads to low coulombic efficiencies (CEs) and safety hazards, which significantly hinders their practical application. In this work, com. Cu foil was modified in situ by Cu₃N nanowires (Cu₃N NWs/Cu) and used as the current collector for a Li anode. In addition to decreasing the true c.d. of the anode and alleviating the volume change during the cycles, Cu₃N reacted with Li during the initial cycle (3Li + Cu₃N → Li3N + 3Cu), which enabled the formation of a Li3N-rich solid electrolyte interphase (SEI). This Li3N-rich SEI with a high ionic conductivity not only boosted Li ion transport but also promoted the homogeneous deposition of Li via increased Li nucleation sites. The improvements in both mass transport and deposition dynamics restrained dendrite growth. As a result, the Cu₃N NWs/Cu anode had stable Li plating/stripping over 270 cycles with a high average CE of 98.6% at 1 mA cm^-2, with Li capacities of 1 mA h cm^-2. A long cycling lifespan of 430 cycles was achieved using a full cell with a high-load LiFePO₄ cathode (mass loading: 10 mg cm^-2) and a Cu3N NWs/Cu-Li anode (N/P = 2.35), demonstrating the effectiveness and practicality of the Cu₃N NWs/Cu current collector in stabilizing the Li anode. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).

The fluidized-bed crystallization (FBC) removes heavy metals onto the fluidized pellets, which is an outstanding alternative to the precipitation method. This study simultaneously recovers iron and copper as binary metal-oxide pellets (Fe^III_0.66Cu^I_0.33 @SiO₂) in a synthetic wastewater using FBC and silica as a seed material. The operating parameters for FBC include the Fe/Cu ratio, pH, cross-sectional loading (L, kg/m².h) and bed height (H, cm) and these are optimized to maximize the crystallization efficiency of iron and copper. At pH = 8, an input Fe/Cu ratio = 2 at a total metal concentration of 3 mM, the crystallization ratio (CR) and the total resp. metal removal (TR) for Fe and Cu is 90% and 99%. Precipitation rates of 0.88 and 0.38 mg-metal/ gr-seed•h were obtained at resp. cross-sectional loadings of 0.25 kg m^-2•h and 0.15 kg m^-2•h for Fe and Cu. The crystal phases of FBC product are resp. characterized as FeOOH and Cu₂O by XRD anal. The high crystallization ratio and the recovery of crystal pellet product indicated that the quantity of the sludge has been reduced significantly in comparison to the traditional chem. precipitation In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Formula: CuH2O2).

Heavy metals in electroplating sludge (ES) are usually amorphous and easily released in the environment. Especially for the ES containing multiple heavy metals, owing to the complex composition and lack of effective disposal method, it has been storage for a long time. In order to avoid environmental pollution, effective treatment methods are very urgent and necessary. Here, chlorinating roasting method was developed to enlarge the phase difference of heavy metals to fulfill the utilization of ES containing multiple heavy metals (Zn, Cr, and Cu). When CaCl₂ was used as additive, Zn and Cu were volatilized to the gas phase, while Cr was oxidized to Cr(V)/(VI) and retained in the solid phase with readily leachable state. The recovery percentage of Zn, Cu, and Cr can reach 99%, 98%, and 96% resp. by chlorinating roasting for 4 h at 1000 °C with the CaCl₂ addition proportion of 100%. After further extraction and purification, the purity of Cr and Zn can reach 92% and 99% resp. Moreover, the mechanism of the differential phase transformation induced by chlorinating roasting was analyzed by the method of thermodn. and kinetics. The kinetic reaction equation of the ZnCl₂ and CuCl₂ volatilization process can be described by phase boundary reaction and the function is G(α) = 1-(1-α)^1/3. This work provides a simple and effective method for the treatment of ES containing multiple heavy metals.

And the article was included in Angewandte Chemie, International Edition in 2022.Quality Control of Cuprichydroxide This article mentions the following:

The degree of pore filling is an important parameter for defining guest@MOF properties in applications including electronics, optics, and gas separation However, the interplay of key aspects of host-guest interactions, such as a quant. description of the guest alignment or the structural integrity of the host as function of pore filling are yet to be determined Polarisation-dependent IR spectroscopy in attenuated total reflection configuration combined with gas sorption allowed to simultaneously study the orientation of the guest mol. and structural changes of the MOF framework during the pore filling process. Thereby we found, that initially randomly oriented guest mols. align with increasing pore filling during adsorption from the gas phase. At the same time, the framework itself undergoes a reversible, guest mol.-dependent rotation of the aromatic linker and a linker detachment process, which induce defects.

Cuprous oxide (Cu₂O) is a promising photocathode candidate for photoelectrochem. (PEC) CO₂ reduction reaction (CO₂RR) due to its narrow band gap and suitable band alignment. However, it suffers from severe photocorrosion, and the real reason is confused. In this work, Cu₂O nanowires film was used as a model photocathode to explore the corrosion behavior during PEC CO₂RR. The evolution of Cu₂O photoelectrodes was monitored by microscopy techniques (scanning electron microscope, transmission electron microscope) and compositional analyses (X-ray diffraction,XPS), more content of Cu was detected after testing under illumination than that in the dark. Polarization curves also show a much higher corrosion current of Cu₂O under illumination. Assisted with the measurement in the existence of electron and hole scavengers, the self-reduction of Cu₂O by the accumulation of photoelectrons is considered as the primary corrosion pathway for Cu₂O photocathode in aqueous solution In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Related Products of 20427-59-2).

Furthermore, the sample COH@NF-LDH/CF is investigated and found to have excellent cycle stability (maintained 86.47% after 5000 cycles).

And the article was included in Industrial Crops and Products in 2022.Application of 20427-59-2 This article mentions the following:

A novel one-pot codeposition strategy was developed by employing bamboo hydrochar as precursors to fabricate magnetic porous char (MPC) with Fe3O4 or α-Fe loading. The synthesized MPC with well dispersed magnetic phase and high thermal stability displayed excellent adsorption capacities and flash adsorption rate for Cu(II) and Pb(II). The batch sorption experiments showed that MPC had the best performance with Langmuir adsorption capacities as high as 125.06 mg/g for Cu(II) and 153.85 mg/g for Pb(II), resp. More importantly, the short time of adsorption reaching 90% equilibrium within 10 min was considerably beyond previous study. Also, a synergistic mechanism of the chem. complexation and phys. adsorption for the higher adsorption capabilities and flash removal rate of the synthesized MPC was proposed. The regeneration investigation revealed that the sorption efficiencies remained at high level with above 92.4% for Cu(II) and 94.1% for Pb(II) after five cycles. Thus, the MPC were expected to be a promising candidate for high-efficient and rapid removal of heavy metal contaminants from wastewater in future practical utilization.
