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

And the article was included in Chinese Journal of Catalysis in 2022.Computed Properties of CuH2O2 This article mentions the following:

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).

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).

Cuprichydroxide (cas: 20427-59-2) belongs to copper catalysts. The evolution of transition metal catalysts has attained a stage of civilization that authorizes for an extensive scope of chemical bonds formation partners to be combined efficiently. It is clear from the impact copper catalysis has had on organic synthesis that copper should be considered a first line catalyst for many organic reactions.Safety 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).

The development of environmentally acceptable benign techniques using purely natural methods is a cost-effective procedure with long-term benefits in all areas. With this consideration, myco synthesized silver nano particles (AgNPs) were studied and it acted as an impending corrosion inhibitor in the environment. Initially, AgNPs were evaluated by phys. and surface characterizations and this evidence demonstrated that RYRE’s water-soluble mols. played an essential role in the synthesis of AgNPs in nano spherical size. The myco synthesized of AgNPs has showed an antibacterial activity against corrosive bacteria in cooling water system (CWS). Hence, the AgNPs were used in biocorrosion studies as an anticorrosive agent along with AgNO₃ and RYRE was also checked. For this experiment, the copper (Cu) metal (CW024) which is commonly used was selected, the result of corrosion rate was decreased, and inhibition efficiency (82%) was higher in the presence of AgNPs in system IV. Even though, AgNO₃ and RYRE had contributed significant inhibition efficiency on Cu at 47% and 61%, resp. According to XRD, the reaction of AgNPs on Cu metal resulted in the formation of a protective coating of Fe₂O₃ against corrosion. EIS data also indicated that it could reduce the corrosion on the Cu metal surface. All of these findings point out the possibility that the myco-synthesized AgNPs were an effective copper metal corrosion inhibitor. As a result, we encourage the development of myco-synthesized AgNPs, which could be useful in the industrial settings.

Roles of supports on reducibility and activities of Cu₃P catalysts for deoxygenation of oleic acid: In situ XRD and XAS studies was written by Kochaputi, Nopparuj;Khemthong, Pongtanawat;Kasamechonchung, Panita;Butburee, Teera;Limphirat, Wanwisa;Poo-arporn, Yingyot;Kuboon, Sanchai;Faungnawakij, Kajornsak;Kongmark, Chanapa.

This work demonstrates for the first time that silicon dioxide (SiO₂) and ultra-stable zeolite Y (USY) supports play significant roles in the reducibility of cupric pyrophosphate (Cu₂P₂O₇) to form copper phosphide (Cu₃P), which consequently affects the selectivity of oleic acid deoxygenation. The formation of supported Cu₃P nanoparticles during hydrogen reduction of Cu₂P₂O₇ was carefully investigated by in situ X-ray diffraction (in situ XRD), and in situ X-ray absorption spectroscopy (in situ XAS). The results indicate that the transformation of Cu₂P₂O₇ to Cu₃P occurs through several steps. In the first step, all supported Cu₂P₂O₇ precursors are reduced to metallic copper. Then, copper particles on SiO₂ support react with phosphorus compounds and directly transform to Cu₃P. On the other hand, copper particles on USY support partially transform to copper diphosphide (CuP₂) and copper hydroxide (Cu(OH)₂) before all converting to Cu₃P. Despite multi-step transformations, Cu₂P₂O₇/USY exhibits the lowest onset reduction temperature and provides Cu₃P with small particle size. The deoxygenation of oleic acid over Cu₃P supported catalysts reaches nearly 100% conversion, both catalysts favor cyclization and aromatization to form cyclic and aromatic compounds The Cu₃P/SiO₂ achieves a higher dodecylbenzene yield (46%) than Cu₃P/USY (33%). A proposed mechanism consists of hydrogenation of oleic acid and deoxygenation, then followed by cracking, cyclization, aromatization, and alkyl rearrangement.

Screening Surface Structure-Electrochemical Activity Relationships of Copper Electrodes under CO₂ Electroreduction Conditions was written by Wahab, Oluwasegun J.;Kang, Minkyung;Daviddi, Enrico;Walker, Marc;Unwin, Patrick R.. And the article was included in ACS Catalysis in 2022.Name: Cuprichydroxide This article mentions the following:

Understanding how crystallog. orientation influences the electrocatalytic performance of metal catalysts can potentially advance the design of catalysts with improved efficiency. Although single crystal electrodes are typically used for such studies, the 1-at-a-time preparation procedure limits the range of secondary crystallog. orientations that can be profiled. This work employs scanning electrochem. cell microscopy (SECCM) together with co-located electron backscatter diffraction (EBSD) as a screening technique to study how surface crystallog. orientations on polycrystalline Cu correlate to activity under CO₂ electroreduction conditions. SECCM measures spatially resolved voltammetry on polycrystalline Cu covering low overpotentials of CO₂ conversion to intermediates, thereby screening the different activity from low-index facets where H₂ evolution is dominant to high-index facets where more reaction intermediates are expected. This approach allows the acquisition of 2500 voltammograms on ∼60 different Cu surface facets identified with EBSD. The order of activity is (111) < (100) < (110) among the Cu primary orientations. The collection of data over a wide range of secondary orientations leads to the construction of an electrochem.-crystallog. stereog. triangle that provides a broad comprehension of the trends among Cu secondary surface facets rarely studied in the literature, [particularly (941) and (741)], and clearly shows that the electroreduction activity scales with the step and kink d. of these surfaces. This work also reveals that the electrochem. stripping of the passive layer that is naturally formed on Cu in air is strongly grain-dependent, and the relative ease of stripping on low-index facets follows the order of (100) > (111) > (110). This allows a procedure to be implemented, whereby the oxide is removed (to an electrochem. undetectable level) prior to the kinetic analyses of electroreduction activity. SECCM screening allows for the most active surfaces to be ranked and prompts in-depth follow-up studies. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2Name: Cuprichydroxide).

Testing the durability of copper based preservative treated bamboos in ground-contact for six years was written by Tomak, Eylem D.;Topaloglu, Elif;Ermeydan, Mahmut A.;Pesman, Emrah.

In this study, durability of bamboo samples in terms of the variability of location along culm height (top, middle and bottom) were evaluated in a ground-contact field test for six years in comparison to Scots pine and beech wood samples. Bamboo and wood samples were treated with Wolmanit-CB (CCB) and Tanalith-E (Tan-E) solutions, and installed in a field located in the North-West of Turkey. The decay resistance of samples was assessed by weight loss, and compared by SEM observations and FTIR anal. Results showed that un-treated bamboo and wood samples had a low durability such that weight losses were found as 64-80% for bamboo and 57-63% for wood samples. SEM micrographs showed the characteristics decay patterns of soft-rot type I and brown-rot fungi in the parenchyma cells, vessels and fibers in vascular bundles. FTIR anal. revealed the mechanism of the biodegradation, which indicates the reduction of carbohydrate content. The weight loss in CCB and Tan-E treated bamboo samples was reduced as 20-45% depending on bamboo height parts, but wood preservatives did not ensure sufficient resistance for six years against soil degrading organisms since more than half of the chem. amount leached out from the bamboos to soil. It was observed that the lower parts of culm were more durable, which was also in accordance with ICP-OES and SEM anal. Copper-based preservatives seemed to be more efficient in pine and beech wood samples than bamboos since the impregnability of bamboo was much lower than that of wood. In the experiment, the researchers used many compounds, for example, Cuprichydroxide (cas: 20427-59-2COA of Formula: CuH2O2).
