A novel strategy was proposed to scrub NO x pollutant originated from sintering flue gases by oxidation combined with wet flue gas denitrification technology. CuCl 2 that could be adopted repeatedly was introduced as an additive into the sulfite solution to enhance NO 2 removal. Comparing with the sulfite solution (0.05 mol/L), the absorption efficiency improved from 75% to 100%, and the stabilization period extended from 10 to 40 min notably with the addition of CuCl 2 . The intensification by CuCl 2 addition was related to the formation of CuCl during the reaction of CuCl 2 and SO 3 2− , which was found to be more effective in removing NO 2 . Afterwards, CuCl transformed to Cu 2+ substance again and this mutual transformation between CuCl and Cu 2+ substance indicated a cyclic use of CuCl 2 additive. Moreover, the feasible reaction pathway was further proved by DFT calculations. Additionally, the investigation on NO 2 absorption at various operating parameters provided theoretical support for the practical application of CuCl 2 in denitrification.

Benzene and 1-dodecene are often alkylated to produce linear alkylbenzene (LAB). LAB is the raw material for the production of linear alkylbenzene sulfonate (LAS), a very important anionic surfactant used in both industrial cleaning and commercial laundry processes, as well as in household laundry detergents. In the present study, we investigated the use of [Et 3 NH]Cl–2AlCl 3 modified with CuCl 2 as a catalyst for the alkylation of benzene with 1-dodecene, specifically looking at the effect of reaction conditions on product activity. The results showed that a conversion of 1-dodecene of 100.0 % and a selectivity of LAB of 93.79 % could be obtained when the following ideal reaction conditions were present: molar ratio of benzene/1-dodecene = 6, reaction temperature = 25 °C, reaction time = 10 min, stirring speed of 1000 rpm and addition of 5.0 mol % CuCl 2 ). The catalyst concentration was 7.0 mol %. FTIR and 31 P-TMPO-NMR measurements were performed to characterise the ionic liquid before and after the addition of CuCl 2 . After the addition of CuCl 2 , it was found that the acidity of the ionic liquid had decreased. The regeneration of the catalyst was also investigated and the cause of inactivation of the catalyst was determined. The results showed that CuCl 2 modified the ionic liquids and decreased the benzene/1-dodecene ratio, but the high product selectivity was maintained.

The dye organic pollutants with utilization in chemical industries have been discharged into the environment, causing the water pollution and human disease. Therefore, developing a cheap, reliable and sustainable wastewater cleaning technology is of great importance. Transitional metal is often one of the active photocatalysts for degradation of dye pollution. Among them, Cu has attracted attention due to low price and catalytic activity. In this article, we took Cu sheets as raw materials and used a simple salting-out method to prepare Cu 2 Cl(OH) 3 nanocomposites, which exhibited a photocurrent response under the UV light. At the same time, the structural transformation process from Cu sheet to nanoparticle Cu 2 Cl(OH) 3 was observed over time. The results showed that Cu 2 Cl(OH) 3 displayed significant photocurrent response. In addition, in order to further improve its catalytic performance, Cu 2 Cl(OH) 3 was modified by different concentrations of carbon dots (CDs) and a wide UV light absorption received. Corresponding to it, 1CDs@OHCu was efficient to the photodegradation of methylene blue (MB) within 3 h compared to the mother sample. The physical properties of prepared samples were studied through XRD, UV–vis spectra, SEM, etc. The related kinetic rate of the process of degrading MB was recorded to determine the role of CDs. The intermediates produced during the photo-reaction was monitored via the chemical trapping agent. By analyzing the characteristics and electrochemical features of prepared samples, the catalytic active center was explored. Finally, stability analysis showed that 1CDs@OHCu could be recycled at least 8 times.

Protonated benzylamine and its N-methylated derivatives, [C6H5CH2NH3−n(CH3)n]+ (n = 0−3), have been adopted as cations in chlorocadmate(II) and chlorocuprate(II) complexes, showing inorganic–organic hybrid architectures. For the Cd(II) compounds, the anionic structures vary from perovskite-type layers (n = 0) to chains (n = 1–3). For Cu(II) compounds, the anionic structures range from perovskite-type layers (n = 0), chains (n = 1) to mononuclear species (n = 2–3). Coordination geometries of the metal ions and intermolecular interactions have been analyzed. Their dielectric properties have been measured.

The recycling of commercial plastics can decrease dependence on fossil fuels. The preparation of carbon electrode materials from commercial plastics can enable the upgrading of waste plastics. Converting low-recycled commercial plastics to value-added porous carbon materials showed great potential toward low-carbon development. However, the conversion of commercial plastics to porous carbon has low yields during pyrolysis and chemical activation. We employed the CuCl2 chemical activator and typical commercial plastics to prepare porous carbon, which achieved high yields exceeding 45%. The release of hydrocarbons during the pyrolysis of commercial plastics is inhibited by the dehydrogenation effect of the CuCl2 activator, while the carbon-rich structure is stabilized by the aromatization reactions of the decomposition species. The porous carbon materials prepared by CuCl2 activation have rich micropores and mesopores. These porous carbons exhibit excellent supercapacitor performance in aqueous electrolytes.

Background Feline calicivirus (FCV) is a common and highly prevalent pathogen causing upper respiratory diseases in kittens and felines in recent years. Due to the substantial genetic variability of the viral genes, existing vaccines cannot provide complete protection. Therefore, research on FCV antiviral drugs has received much attention.Results In this study, we found that copper chloride had dose-dependent antiviral effects on FCV in F81 cells. We also found that the combination of copper chloride and ribavirin had a synergistic protective effect against FCV in F81 cells. In contrast, the combination of copper chloride and horse anti-FCV immunoglobulin F (ab’)2 showed an antagonistic effect, likely because copper chloride has an effect on F (ab’)2 immunoglobulin; however, further research is needed to clarify this supposition.Conclusion sIn summary, we found that copper chloride had low cytotoxicity and significant antiviral effects on FCV in F81 cells, providing a new drug candidate for the prevention and treatment of FCV infection.

Although two-dimensional (2D) non-van der Waals (non-vdW) heterostructures with intriguing physical and chemical merits have the potential application in rechargeable batteries, they still lack valid synthetic methods due to their three-dimensional chemical bonding characteristics. Here, a facile one-step method to synthesize the 2D non-vdW V 8 C 7 /V 2 O 3 heterostructure based on the conversion of V 2 AlC MAX phase in the molten copper chloride is developed. Accompanied with the aluminium layer etching, the V 2 AlC precursor is transformed into the intermediate product (i.e., 2D non-vdW V 8 C 7 ). Interestingly, an operando conversion from the intermediate 2D non-vdW V 8 C 7 to the final 2D non-vdW V 8 C 7 /V 2 O 3 heterostructure is achieved via the extrinsic adsorbed oxygen. Similarly, other types of halogenated salts, including copper bromide and cuprous iodide, can also be as etchants to obtain the 2D non-vdW V 8 C 7 /V 2 O 3 heterostructure. Owing to the 2D character and unique hetero-structure, the obtained 2D non-vdW V 8 C 7 /V 2 O 3 heterostructure can be used as a superior cathode of sodium metal batteries. Meanwhile, the resultant 2D non-vdW V 8 C 7 /V 2 O 3 heterostructure can also enhance the whole performance of aqueous zinc-iodine batteries. This new construction method of 2D non-vdW heterostructures facilitates the development of high-performance rechargeable batteries.

Fenton catalytic medicine that catalyzes the production of ·OH without external energy input or oxygen as a substrate has reshaped the landscape of conventional cancer therapy in recent decades, yet potential biosafety concerns caused by non-safety-approved components restrict their clinical translation from the bench to the bedside. Herein, to overcome this dilemma, we elaborately utilizate safety-approved hetastarch, which has been extensively employed in the clinic as a plasma substitute, as a stabilizer participating in the copper chloride-initiated polymerization of pyrrole monomer before loading it with DOX. The constructed DOX-loaded hetastarch-doped Cu-based polypyrrole (HES@CuP-D) catalyzes the excess H2O2 in tumor cells to ·OH through a Cu+-mediated Fenton-like reaction, which not only causes oxidative damage to tumor cells but also leads to the structural collapse and DOX release. Additionally, HES@CuP-D together with laser irradiation reinforces tumor killing efficiency by hyperthermia-enhanced catalytic activity and -accelerated drug release. As a result, the developed HES@CuP-D provides a promising strategy for Fenton catalytic therapy with negligible toxicity to the body.

Copper halides have attracted extensive interest because of the merits of environmental friendliness, low lost, and superior optoelectronic properties. However, the stability issue heavily hinders their commercial application. Herein, the successful synthesis of copper chlorine in glass using melting-quenching method under vacuum condition is reported. By introducing CuCl into the glass matrix (CuCl@glass), the as-fabricated samples emit white or yellow light, which depends on the ratios of CuCl:glass. The maximum values of the photoluminescence quantum yield are found to be 37% and 26%, respectively. With the addition of CsCl, CsCu 2 Cl 3 , and Cs 3 Cu 2 Cl 5 phases form in the glass, leading to the phosphor-in-glass which emits green light. A maximum luminous yield of 74% is achieved. Based on the synthesized samples, light-emitting diodes are successfully prepared by the remote packaging technology, and the utilization of the as-obtained composites for anticounterfeiting application is realized. Herein, an effective approach for the preparation of lead-free halide perovskite@glass composites is provided, opening up potential commercial applications.

Ammonia (NH 3 ) is widely recognized as a carbon-free hydrogen carrier with high energy density, making it a promising energy vector for sustainable energy systems. However, its efficient storage and release remain technical challenges. In this study, the low-temperature NH 3 adsorption-desorption performance of four pure metal chlorides (CaCl 2 , MgCl 2 , MnCl 2 , and CuCl 2 ) was systematically evaluated. Among them, CuCl 2 and MnCl 2 exhibited superior NH 3 uptake capacities, but also suffered from volume expansion and particle agglomeration during repeated cycling. To overcome these limitations, composite sorbent pellets were developed by supporting metal chlorides on Al 2 O 3 via a graphite-casting method. The resulting CuCl 2 -based composite pellet achieved an optimized balance of high NH 3 adsorption capacity (∼ 0.36 g NH 3 /g), excellent regeneration efficiency (> 96 %), and adequate mechanical strength. Excessive CuCl 2 loading reduced both regeneration efficiency and mechanical stability, while lower loading enhanced active phase dispersion and sorbent performance. 30 wt% CuCl 2 offered the best performance in terms of adsorption, regeneration, and structural durability. Additionally, the optimized Cu 30 -Al-C sorbent maintained stable NH 3 adsorption capacity over 20 cycles, confirming excellent reusability. The enhanced performance was attributed to the synergistic effects of Al 2 O 3 support and the hydrophobic nature of the graphite-casting process, which enabled uniform distribution of active compound and mitigated structural deterioration during cycling. These results demonstrate the feasibility of graphite-casted, Al 2 O 3 -supported metal chlorides as structurally stable and regenerable NH 3 sorbents for low-temperature ammonia storage applications.

In this study, we first achieve effective generation of reactive chlorine species (RCS) by molecular oxygen (O 2 ) activation on a copper chloride loaded hydrothermal carbonaceous carbon (CuCl-HTCC). O 2 can be adsorbed and activated by the cuprous (Cu(I)) from the CuCl-HTCC, and then converted into superoxide radical-hydrogen peroxide-hydroxyl radical, and chloride on the surface of CuCl-HTCC can be converted to RCS. This system holds two advantages: (1) plenty of Cu(I) exists in CuCl-HTCC can contribute to O 2 activation heterogeneously. Its efficiency is much higher than that of homogeneous reactions in which Cu(I) cannot exist stably; (2) this process is a rapid heterogeneous process. Cu(I) can contribute to RCS generation with very fast kinetic through multi-steps. As a result, 10 mg/L of pollutants like phenol or ibuprofen were almost completely degraded in 120 min. This is a new and efficient method for generating RCS through the O 2 activation process.

Upon harnessing low-intensity ultrasound to activate sonosensitizers, sonodynamic therapy (SDT) induces cancer cell death through the reactive oxygen species (ROS) mediated pathway. Compared with photodynamic therapy (PDT), SDT possesses numerous advantages, including deeper tissue penetration, higher accuracy, fewer side effects, and better patient compliance. Sinoporphyrin sodium (DVDMS), a sonosensitizer approved by the FDA, has drawn abundant attention in clinical research, but there are some deficiencies. In order to further improve the efficiency of DVDMS, many studies have applied self-assembly nanotechnology to modify it. Furthermore, the combined applications of SDT/chemodynamic therapy (CDT) have become a research hotspot in tumor therapy. Therefore, we explored the self-assembly of nanoparticles based on DVDMS and copper to combine SDT and CDT. A cost-effective sonosensitizer was synthesized by dropping CuCl2into the DVDMS solution with the assistance of PVP. The results revealed that the nanostructures could exert excellent treatment effects on tumor therapy and perform well for PET imaging, indicating the potential for cancer theranostics. In vitro and in vivo experiments showed that the nanoparticles have outstanding biocompatibility, higher ROS production efficiency, and antitumor efficacy. We believe this design can represent a simple approach to combining SDT and CDT with potential applications in clinical treatment and PET imaging.Keywords:sonodynamic therapy;chemodynamic therapy;theranostics;DVDMS;self-assembly
