Shape-controlled synthesis of copper based multinary sulfide catalysts for enhanced photocatalytic hydrogen evolution

In this study, for the first time, phase and shape controlled copper-based multinary sulfide (M:CuxS, M: Ni, Co, Mn and Zn) nanorods were synthesized using different ratios of dopants. These nanorods were used as the catalyst for the photocatalytic hydrogen evolution, and the effect of the doped metals was investigated under sunlight illumination in the presence of eosin-Y and triethanolamine as a photosensitizer and a sacrificial donor agent, respectively. The reaction rates of hydrogen evolution were found in the order of Ni:CuxS > Co:CuxS > Mn:CuxS > Zn:CuxS as 4.0, 1.2, 0.9 and 0.7 mmol g(-1) h(-1), respectively. The strategy proposed here is straightforward, holding a great potential to produce high-efficiency catalytic activity and stability of Ni doped CuxS nanorods when compared to the others.

CO2 reduction by single copper atom supported on g-C3N4 with asymmetrical active sites

Electrochemical reduction of CO2 requires catalysts beyond Cu with high activity and selectivity to produce C-2 products. Different from many single-atom catalysts that show high performance in obtaining C-1 products, Cu supported on carbon nitride (Cu-C3N4) has shown a unique capability to generate C-2 products by providing asymmetrical active sites. Herein, we study 17 possible pathways and reaction mechanisms of CO2 reduction toward ethylene – a featured C-2 product, on Cu-C3N4. The possible reaction intermediates along with different reaction pathways on three active sites of Cu-C3N4 (Cu, C, and N) were obtained by density functional theory (DFT) computations. The most probable reaction pathway toward C2H4 production is 1.08 eV at open circuit conditions, which is benefited by the synergistic effect of both Cu and C active sites. Comparing with other pathways utilizing Cu/N and C/N active sites, the carbon atom provides a perfect settling centre for the first CO2 after reduction by Cu and leaves Cu vacant for the second CO2 reduction. Our study provides reaction mechanism insights for C-2 production on Cu-C3N4 and sheds light on designing electrocatalysts with dual active sites.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2568-25-4 help many people in the next few years. HPLC of Formula: C10H12O2.

Sulfamethoxazole degradation by the CuOx/persulfate system

In the present study, the efficiency of immobilized CuOx catalyst for sodium persulfate (SPS) activation was investigated. The efficiency of the CuOx/SPS system was evaluated for sulfamethoxazole (SMX), an antibiotic agent, degradation. CuOx nanoparticles were grown on TiO2 pellets, serving as supporting material. Information about the morphology and physicochemical characteristics of the catalyst was obtained by means of BET, SEM and XRD. The activity of CuOx/SPS system was first studied in a batch reactor resulting in complete 0.5 mg/L SMX removal in 90 min. SMX degradation followed pseudo-first-order kinetics. The effect of SPS (100-500 mg/L) concentration was also tested. Additional experiments were carried out under simulated solar irradiation showing the existence of synergistic phenomena. The performance of the CuOx/SPS system was further evaluated under real and synthetic water matrices. Apparent rate constant decreased from 0.028 min(-1) in ultrapure water to 0.007 min(-1) and 0.003 min(-1) in the case of bottled water and wastewater, correspondingly. SMX removal was mainly hindered by the presence of bicarbonate. The by-products of SMX degradation were identified by LC-MS-TOF. In order to investigate the long-term performance of the present system, the CuOx/SPS process was operated in a continuous-flow mode at a flow rate of 0.56 mL/min (corresponding to residence time of 40 min); under these conditions, SMX removal remained remarkably stable at similar to 80 % for 118 h or operation.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2568-25-4, in my other articles.

Copper Supported onto Magnetic Nanoparticles as an Efficient Catalyst for the Synthesis of Triazolobenzodiazepino[7,1-b]quinazolin-11(9H)-ones via Click N-Arylation Reactions

A novel catalyst is designed and synthesized based on immobilization of copper onto modified magnetic nanoparticles. The catalyst was characterized by several characterization techniques. The catalyst was applied for the synthesis of a novel series of heterocyclic scaffold containing a 1,4-benzodiazepine fused with a 1,2,3-triazole ring and a quinazolin-11(9H)-one skeleton. The method is based on the direct synthesis of quinazolin-11(9H)-one ring by the reaction of isatoic anhydride (or anthranilic acid) and propargylamine, and an aldehyde, containing a leaving group on its aromatic ring. The reaction contains an in situ sequential click reaction of azide group with terminal alkyne and subsequent N-arylation reaction to afford the final products. The method benefits various advantages, such as regioselectivity and high yield of the products. The reusability of the catalyst was evaluated and the results showed that the catalyst is highly reusable in 10 sequential reactions.

Electrochemical hydrogen storage behavior of Ni-Ceria impregnated carbon micro-nanofibers

A hierarchical porous structured carbon micro-nanofiber containing the bimetallic configuration of the nickel (Ni) and ceria (CeO2) nanoparticles (NPs) was synthesized and tested for the electrochemical hydrogen (H-2) storage capacity. The electrode exhibited a high H-2 storage capacity of 498 mA h/g or 1.858% (w/w) at the charge-discharge current density of 500 mA/g. A mechanistic insight showcased the combined contributions of the high surface area containing activated carbon microfiber (ACF) substrate, the graphitic carbon nanofibers (CNFs), and the Ni and CeO2 NPs, towards the augmented electrochemical H-2 storage capacity and cyclic stability of the fabricated Ni-CeO2-CNF/ACF electrode. Ni served as the catalyst for growing the CNFs via chemical vapor deposition as well as for storing H-2 via spillover mechanism, while CeO2 created the charge carrier vacancies in the material. The measured cycle retention capacity of 99% and charge-discharge efficiency of 97.6% confirm the electrochemically stable characteristics of Ni-CeO2-CNF/ACF, and clearly indicate it to be an economically viable and efficient H-2-storage material.

A Copper(I) oxide-zinc oxide nano-catalyst hybrid: Brief characterization and study of the kinetic of its photodegradation and photomineralization activities toward methylene blue

In this study, as-prepared coupled copper(I) oxide-zinc oxide (Cu2O-ZnO) nanoparticles were briefly characterized by X-ray diffraction (XRD), Fourier-transform infrared (FTIR), diffuse reflectance spectroscopy (DRS), and scanning electron microscope/energy-dispersive X-ray methods, followed by testing their photocatalytic activity toward the photodegradation and photomineralization of methylene blue (MB). The cubic phase of Cu2O and the hexagonal wurtzite ZnO crystallite phases were detected in the XRD pattern of the nano-composite. In addition, the average crystallite sizes of 22.15, 11.11, and 17.85 nm, as well as 46, 35, and 61 nm were estimated for the as-prepared ZnO, Cu2O, and Cu2O-ZnO samples by the Scherrer and the Williamson-Hall equations, respectively. Further, the bandgap energy (Eg) values of 3.12, 2.23, and 2.29 eV were obtained for the above-mentioned samples corresponding to their absorption-edge wavelengths of 398, 555, and 541 nm, respectively. Based on the findings, FTIR confirmed the synthesis of cubic Cu2O crystals during the synthesis procedure. Furthermore, direct photolysis and surface adsorption processes removed 1.7 and 2% of MB while the photodegradation process by ZnO, Cu2O, and Cu2O-ZnO simultaneously removed 35.1, 50.1, and 78.0% of MB molecules, respectively. The coupled system with the Cu2O:ZnO mole ratio of 1:2 showed the highest activity. Finally, the rate constant values of 0.0198 and 0.0192 min(-1) corresponding to the t(1/2) values of 35 and 36.1 min were obtained for MB photodegradation and photomineralization, respectively.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 2568-25-4 is helpful to your research. Recommanded Product: 2568-25-4.

Efficient persulfate non-radical activation of electron-rich copper active sites induced by oxygen on graphitic carbon nitride

Peroxymonosulfaie (PMS) non-radical reactions possess high catalytic activity for specific pollutants under complex water environmenis. However, the synthesis of high-performance catalysts and the discussion of non-radical reaction mechanisms are still unsatisfactory. Here, a novel and efficient non-radical catalyst (O-CuCN) was successfully assembled using the scheme of Copper (Cu) and oxygen (O) co-doping. The O element with great electronegativity induces graphite carbon nitride (g-C3N4) to act as a medium to change the phase properties and electron density distribution of g-C3N4, and provides a support for the targeting of Cu. Cu is introduced into g-C3N4 as an active site in the phase structure, and an electron-rich center with the Cu site is formed, which forms a metastable intermediate after the adsorption of PMS by Cu as the active site. The new catalyst O-CuCN has outstanding activity in the PMS system, and its degradation rate for bisphenol A (BPA) is increased by more than 20 times compared to that of g-C3N4, and it has excellent environmental tolerance and stability. This work demonstrates that the formation of metastable intermediates and the initiation of effective non radical reactions can be achieved by constructing differentiated electron density structures.

Catalytic reduction of 4-nitrophenol using copper terephthalate frameworks and CuO@C composite

Two-dimensional (2D) metal-organic frameworks (MOFs), called copper-terephthalate, and CuO@C were investigated as catalysts for the reduction of 4-nitrophenol (4-NP) via hydrogenation using sodium borohydride (NaBH4) as a reducing agent. Copper-terephthalate frameworks were synthesized using the solvothermal method. While, CuO@C was synthesized using carbonization of copper-terephthalate at temperature of 400 degrees C, 500 degrees C, 600 degrees C, and 700 degrees C. Both materials displayed a complete reduction of 4-NP to 4-aminophenol (4-AP) in a short time (3 min) with a rate of 15.1×10(-3) min(-1), and 6.0×10(-3) min(-1) at room temperature for CuBDC, and CuO@C, respectively. The materials could be used for more than five times without obvious fading in their catalytic activities. The mechanism of the reduction was also discussed. The materials are promising for catalytic applications such as organic synthesis via the reduction of the nitro groups.

Anion-Dependent Catalytic C-C Bond Cleavage of a Lignin Model within a Cationic Metal-Organic Framework

The development of heterogeneous catalysts capable of selectively converting lignin model compounds into products of added value offers an exciting avenue to explore in the production of renewable chemical feedstocks. The use of metal- organic frameworks (MOFs) in such chemical transformations relies largely on the presence of accessible open metal sites found within highly porous networks that simultaneously allow for fast transport and strong interactions with desired substrates. Here, we present the first systematic study on the modulation of catalytic performance of a cationic framework, [Cu-2(L)(H2O)(2)](NO3)(2)center dot 5.5H(2)O (L = 1,1′-bis(3,5-dicarboxylatophenyl)-4,4′-bipyridinium), achieved through the exchange of anionic guests. Remarkably, the catalytic activity proves to be highly anion-dependent, with a nearly 10-fold increase toward the aerobic C-C bond cleavage of a lignin model compound when different anionic species are incorporated within the MOF. Moreover, we demonstrate that the cationic nature of the MOF, imparted by the incorporation of viologen moieties within the linker, tunes the electrophilicity of the active copper(II) sites, resulting in stronger interactions with the substrate. As such, the copper-based framework exhibits enhanced catalytic performance when compared to its neutral counterpart, emphasizing the appeal of charged frameworks for use as green heterogeneous catalysts.
