As visible light-driven photocatalysts in wastewater treatment, Cu₂O/CuO composites have garnered considerable attention. Herein, Cu₂O/CuO core-shell nanowires were fabricated directly on a Cu mesh using a simple two-step synthesis process involving a wet chem. method and rapid annealing. Unlike conventional composite nanowires, controllable core-shell nanowires exhibit high photoelectrochem. properties and overcome the problems associated with the recovery of powder-based photocatalysts. The presence and structural distribution of the Cu₂O/CuO core-shell nanowires were confirmed using X-ray diffraction, XPS and transmission electron microscopy. Among the samples subjected to different rapid annealing temperatures for 180 s, the sample exposed to rapid annealing at 350°C achieved the highest photocurrent d. of -6.96 mA cm^-2. In the core-shell nanowires fabricated on the samples, the ratio of Cu₂O/CuO was 1:1. The photocatalytic activity of the Cu₂O/CuO nanowire samples was also determined by measuring methyl blue degradation to determine their applicability in wastewater treatment. A remarkable photocatalytic degradation rate of 91.6% was achieved at a loading bias voltage of -0.5 V. The Cu₂O/CuO heterojunction enhanced the photodegradation of the samples because the different bandgaps improved the dissociation of the photogenerated electron-hole pairs. Furthermore, the antibacterial activity of the Cu₂O/CuO nanowires exhibited considerable resistance against Escherichia coli and photocatalytic antibacterial treatment for only 20 min under visible light killed 106 CFU/mL of E. coli. Therefore, the Cu₂O/CuO controllable core-shell nanowires with a high photodegradation performance and excellent antibacterial activity under general illumination show diverse applications in water treatment. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).

Transition metal selenides (TMSs) have enthused snowballing research and industrial attention due to their exclusive conductivity and redox activity features, holding them as great candidates for emerging electrochem. devices. However, the real-life utility of TMSs remains challenging owing to their convoluted synthesis process. Herein, a versatile in situ approach to design nanostructured TMSs for high-energy solid-state hybrid supercapacitors (HSCs) is demonstrated. Initially, the rose-nanopetal-like NiSe@Cu₂Se (NiCuSe) pos. electrode and FeSe nanoparticles neg. electrode are directly anchored on Cu foam via in situ conversion reactions.

Micro-Nano-Nanowire Triple Structure-Held PDMS Superhydrophobic Surfaces for Robust Ultra-Long-Term Icephobic Performance was written by Chen, Changhao;Tian, Ze;Luo, Xiao;Jiang, Guochen;Hu, Xinyu;Wang, Lizhong;Peng, Rui;Zhang, Hongjun;Zhong, Minlin. And the article was included in ACS Applied Materials & Interfaces in 2022.SDS of cas: 20427-59-2 This article mentions the following:

Anti-icing superhydrophobic surfaces have attracted tremendous interests due to their repellency to water and extremely low ice affinity, whereas the weak durability has been the bottleneck for further applications. Surface durability is especially important in long-term exposure to low-temperature and high-humidity environments. In this study, a robust micro-nano-nanowire triple structure-held PDMS superhydrophobic surface was fabricated via a hybrid process: ultrafast-laser-prepared periodic copper microstructures were chem. oxidized, followed by modification of PDMS. The hedgehog-like surface structure was composed of microcones, densely grown nanowires, and tightly combined PDMS. The capillary force difference in micro-nanostructures drove PDMS solutions to distribute evenly, bonding fragile nanowires to form stronger composite cones. PDMS replaced the commonly used fragile fluorosilanes and protected nanowires from breaking, which endowed the surfaces with higher robustness. The ductile PDMS-nanowire composites possessed higher resiliency than brittle nanowires under a load of 1 mN. The surface kept superhydrophobic and ice-resistant after 15 linear abrasion cycles under 1.2 kPa or 60 icing-deicing cycles under -20°C or 500 tape peeling cycles. Under a higher pressure of 6.2 kPa, the contact angle (CA) was maintained above 150° until the abrasion distance exceeded 8 m. In addition, the surface exhibited a rare spontaneously optimized performance in the icing-deicing cycles. The ice adhesion strength of the surface reached its lowest value of 12.2 kPa in the 16th cycle. Evolution of surface roughness and morphol. were combined to explain its unique U-shaped performance curves, which distinguished its unique degradation process from common surfaces. Thus, this triple-scale superhydrophobic surface showed a long-term anti-icing performance with high deicing robustness and low ice adhesion strength. The proposed nanostructure-facilitated uniform distribution strategy of PDMS is promising in future design of durable superhydrophobic anti-icing surfaces. 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. Copper catalyst has received great attention owing to the low toxicity and low cost.

Cu is widely used to prepare high-value products in photocatalytic CO₂ reduction reaction (CO₂PR). The valence state of transition metals usually has a great impact on the catalytic process. However, the research on Cu valence in CO₂PR is lack for its complex valence change. In current work, Cu_x/P25 with stable Cu valence composition in CO₂PR is prepared The results show that Cu is composed of Cu⁰ and Cu₂O, and their proportions change regularly as Cu loading changing, which are linearly related to the selectivity of the corresponding products of CO₂PR.

Regulating the Li Nucleation/Growth Behavior via Cu₂O Nanowire Array and Artificial Solid Electrolyte Interphase toward Highly Stable Li Metal Anode was written by Liu, Xin-Fang;Xie, Dan;Tao, Fang-Yu;Diao, Wan-Yue;Yang, Jia-Lin;Luo, Xiao-Xi;Li, Wen-Liang;Wu, Xing-Long. And the article was included in ACS Applied Materials & Interfaces in 2022.Quality Control of Cuprichydroxide This article mentions the following:

Lithium (Li) metal was considered to be the most promising anode material for next-generation rechargeable batteries. Unfortunately, the hazards induced by dendrite growth and volume fluctuation hinder its commercialized application. Here, a three-dimensional (3D) current collector composed of a vertically aligned Cu₂O nanowire that is tightly coated with a polydopamine protective layer is developed to solve the encountered issues of lithium metal batteries (LMBs). The Cu₂O nanowire arrays (Cu₂O NWAs) provide abundant lithiophilic sites for inducing Li nucleation selectively to form a thin Li layer around the nanowires and direct subsequent Li deposition. The well-defined nanochannel works well in confining the Li growth spatially and buffering the volume change during the repeated cycling. The PDA coatings adhered onto the outline of the Cu₂O NWAs serve as the artificial solid electrolyte interface to isolate the electrode and electrolyte and retain the interfacial stability. Moreover, the increased specific area of copper foam (CF) can dissipate the local c.d. and further suppress the growth of Li dendrites. As a result, CF@Cu₂O NWAs@PDA realizes a dendrite-free morphol. and the assembled sym. batteries can work stably for over 1000 h at 3 mA cm^-2. When CF@Cu₂O NWAs@PDA is coupled with a LiFePO₄ cathode, the full cells exhibit improved cycle stability and rate performance. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Quality Control of Cuprichydroxide).

In situ growth of nanostructured copper and zinc mixed oxides on brass supports as efficient microreactors for the catalytic CO oxidation was written by Cabello, Ana P.;Ulla, Maria A.;Zamaro, Juan M.. And the article was included in Journal of Materials Science in 2022.Name: Cuprichydroxide This article mentions the following:

This work analyzed the in situ growth of nanostructured films of copper and zinc mixed oxides on brass substrates by a simple vapor oxidation route and their use as microreactors for the catalytic oxidation of CO. Thin and well-anchored films of nano-oxides were obtained, while the evolution over time of the physicochem. characteristics during growth was studied by XRD, SEM, EDS, LRS and XPS. At short treatment times a total coverage of the substrate with nano-oxide growths was obtained in a sequence in which first a base layer of zinc oxide was produced over which, subsequently, an increasing surface proportion of copper oxides progressively evolved. This stratification is a unique characteristic that contrasts with that of films obtained by conventional thermal treatments in air in which an outer layer of zinc oxide is produced. In this way, the study shed light on the understanding of the in situ growth mechanism of nano-oxides on brass substrates. Furthermore, this system showed a good performance for the catalytic CO oxidation reaction at relatively low temperatures, combining several attributes such as activity, reaction stability, low-cost materials and a simple and mild synthetic methodol. The non-noble metal-based microreactor with highly stabilized nano-oxide structures onto brass became an efficient and low-cost alternative for the catalytic CO oxidation reaction. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Name: Cuprichydroxide).

This study estimated health risks due to two types of copper-based nanoagrochems. (Cu (OH)₂ and CuO nanoparticles (NPs)), during inadvertent ingestion of soil and consumption of leafy vegetables for a hypothetical exposure scenario. The dissolution of copper-based nanoagrochems. in human digestive system was considered for estimating realistic doses. No risk was found during soil ingestion (hazard quotient (HQ) <1). HQ (no dissolution of Cu (OH) ₂ nanopesticides) (HQ= 0.015) comes out to be 2 times higher than that of HQ (100% dissolution of Cu (OH)₂ nanopesticides into copper ions) (HQ= 0.007). In case of risk from consumption of leafy vegetables, the following order of risk was found (high to low HQ value): Cu (OH)₂ (HQ= 1925) >CuO NPs (1402). Combined exposure of Cu (OH)₂ nanopesticide through soil ingestion as well as consumption of contaminated edible leafy vegetables resulted in health risks. The calculated maximum allowable applicable concentration values of Cu (OH)₂ and CuO NPs without posing risk to human and plant toxicity were found to be 1.14 and 0.45 mg/L, resp. These findings can be used now for deciding safe use of copper-based nanoagrochems.

The transformation of CO₂ into value-added products is a hot research topic. Metal copper as an electrochem. catalyst shows activity for generating multi-carbon products in CO₂ electroreduction Herein, Cu₂S nanorods/copper mesh (Cu₂S/CM) is successfully fabricated, and exhibits high performance of CO₂ electroreduction to ethanol.
