In this work, Sb^(3+)/Te^(4+)ions doped Zn-based halide single crystals(SCs) with two STEs emissions have been synthesized and the possibility of its anti-counterfeiting application was explored.Further, the relationship between the strength of electron-phonon coupling and photoluminescence quantum yields(PLQYs) for STEs in a series of metal halides has been studied. And the semi-empirical range of the Huang-Rhys factors(S) for metal halides with excellent photoluminescence(PL) property has been summarized. This work provides ideas for further research into the relationship between luminescence performance and electron-phonon coupling of metal halides, and also provides a reference for designing the metal halides with high PLQYs.展开更多

Here,the emission intensity of(C_(12)H_(24)O_(6))_(2)Na_(2)(H_(2)O)_(3)Cu_(4)I_(6) was strengthened between 9.3 GPa and 17.2 GPa, accompanied by the redshift of emission wavelength. The photoluminescence(PL) of Cu(Ⅰ)-based organometallic halides originates from multiple emission states, which are a metal-to-ligand charge transfer or a halide-to-ligand charge transfer(MLCT/HLCT)excited state and a cluster-centered(CC) excited state. MLCT/HLCT-related emission wavelength redshifts while CCrelated emission wavelength remains unchanged, indicating that the rearrangement of different emission states plays a critical role in the changes of luminescence wavelength. This study not only deepens the understanding of the influence of high pressure on(C_(12)H_(24)O_(6))_(2)Na_(2)(H_(2)O)_(3)Cu_(4)I_(6), but also provides valuable insights into the structure–property relationship of zero-dimensional Cu(Ⅰ)-based organometallic halides.展开更多

文摘Existing organic halide synthesis routes typically employ elemental halogens(X_(2),X=Cl or Br),leading to low atom economy and significant environmental pollution.In this work,we developed an atom efficient electrosynthesis and separation strategy for halogenation reagents—N-chlorosuccinimide(NCS)and N-bromosuccinimide(NBS)—at high current densities.Faradic efficiency(FE)of 91.0%and 81.3%was achieved for NCS and NBS generation on RuO_(x)/TiO_(2)/Ti in a batch cell,respectively.Electrosynthesis of NCS likely involves both heterogeneous catalytic and homogeneous tandem pathways,while NBS is likely formed in a Langmuir-Hinshelwood mechanism with a proton-coupled electron transfer as the rate-determining step.A coupled continuous electrocatalytic synthesis and in situ separation setup was developed for the efficient production of NCS and NBS,which yielded 0.77 g of NCS in 12000 s and 0.81 g of NBS in 15000 s,both with relative purity exceeding 95%.The halogenation of acetone using NCS and NBS enabled gram-scale production of the key intermediate in organic synthesis,1-halogenacetone,with over 95%recovery of succinimide.

文摘Self-trapping excitons(STEs) emission in metal halides has been a matter of interest, correlating with the strength of electron-phonon coupling in the lattice, which are usually caused by ions with ns~2 electronic structure. In this work, Sb^(3+)/Te^(4+)ions doped Zn-based halide single crystals(SCs) with two STEs emissions have been synthesized and the possibility of its anti-counterfeiting application was explored.Further, the relationship between the strength of electron-phonon coupling and photoluminescence quantum yields(PLQYs) for STEs in a series of metal halides has been studied. And the semi-empirical range of the Huang-Rhys factors(S) for metal halides with excellent photoluminescence(PL) property has been summarized. This work provides ideas for further research into the relationship between luminescence performance and electron-phonon coupling of metal halides, and also provides a reference for designing the metal halides with high PLQYs.

文摘Mercury removal from coal combustion flue gas remains a significant challenge for environmental protection due to the lack of cost-effective sorbents.In this study,a series of red mud(RM)-based sorbents impregnated with sodium halides(NaBr and NaI)are presented to capture elemental mercury(Hg^(0))from flue gas.The modified RM underwent comprehensive characterization,including analysis of its textural qualities,crystal structure,chemical composition,and thermal properties.The results indicate that the halide impregnation substantially impacts the surface area and pore size of the RM.Hg^(0) removal performance was evaluated on a fixed-bed reactor in simulated flue gas(consisting of N_(2),O_(2),CO_(2),NO and SO_(2),etc.)on a modified RM.At an optimal adsorption temperature of 160℃,NaI-modified sorbent(RMI5)offers a removal efficiency of 98%in a mixture of gas,including O_(2),NO and HCl.Furthermore,pseudo-second-order model fitting results demonstrate the chemisorption mechanism for the adsorption of Hg^(0) in kinetic investigations.

文摘In this paper,the research progress of Cu-based catalyst and the activity enhancement strategies in the hydrogenation of dimethyl oxalate(DMO)to ethylene glycol(EG)was reviewed.As a green and economical ethylene glycol production path,the core of DMO hydrogenation of EG lies in the rational design and optimization of catalysts.This paper first introduces the background of the DMO hydrogenation system EG significance and the important effect of Cu-based catalyst in the reaction,particularly emphasizing the coordination with the Cu^(+)-Cu^(0) species catalytic effect.Then,many factors affecting the activity of Cu-based catalysts were analyzed in detail,including the equilibrium effect between Cu^(0) and Cu+species,the surface dispersion of Cu species,the interaction between metal and support,and the morphology effect of the catalyst.Regarding strategies for improving catalyst performance,this paper summarized effective measures such as optimizing support structure,adding promoters and optimizing preparation methods,and demonstrated the practical application effects of these strategies through representative catalyst examples.In addition,this paper also discusses the complex relationship between the influencing factors and catalyst performance.It points out the key directions for future research,with in-depth exploration of the correlation between catalyst structure and performance,the development of new catalysts,and the application of machine learning and big data technology in the catalyst research and development.In summary,this paper provides comprehensive theoretical guidance and practical reference for the performance optimization of Cu-based catalysts for DMO hydrogenation to EG.

文摘The next-generation lithium(Li)metal batteries suffer severe low-temperature capacity degradation,appealing for expeditions on solutions.Herein,the feasibility of copper-based skeletons(i.e.,2D Cu foil,3D Cu mesh,and CuZn mesh)frequently adopted in the stabilization of Li are evaluated at low temperatures.Li growth patterns and stripping behaviors on different skeletons and at different temperatures uncover the dendrite-free and dead-Li-less Li deposition/dissolution on CuZn mesh.Three-electrode impedance indicates the dynamic advantages of CuZn mesh,driving fast Li^(+)crossing through solidelectrolyte-interphase and charge transfer process.Notably,CuZn mesh enables the stable operation and fast charging(1.8 mA cm^(-2))of Li||LiFePO_(4)cells for over 120 cycles at-10℃ with a superior capacity retention of 88%.The success of CuZn mesh can be translated into lower temperature(-20℃)and 1.0-Ah-level pouch cells.This work provides fundamentals on improving low-temperature battery performances by skeletons with regulated spatial structure and lithiophilicity.

文摘Herein,we have developed a sustainable linear paired electrolysis strategy for the redox-neutral benzylation of N-heteroarenes with benzyl halides using solid ion resin as the recyclable electrolyte.This method sufficiently utilizes both cathodic and anodic reactions to produce a variety of benzylated Nheteroarenes,features high atom-and step-economy,excellent energy efficiency,operational simplicity,good functional group tolerance,mild conditions and no requirement of sacrifice reagent and base additive.Importantly,the inexpensive and commercially available solid ion resin electrolyte was validated in both gram-scale synthesis and electrolyte cycling experiment.We hope this strategy not only provides a sustainable synthetic strategy for benzylated compounds but also develops the further utilization of ion resin in electrosynthesis as well as linear paired electrolysis.

文摘Low-dimensional hybrid metal halides exhibit broadband emission and high photoluminescence quantum yield(PLQY), making them promising candidates for the next-generation luminescent materials in lighting applications. Here,the emission intensity of(C_(12)H_(24)O_(6))_(2)Na_(2)(H_(2)O)_(3)Cu_(4)I_(6) was strengthened between 9.3 GPa and 17.2 GPa, accompanied by the redshift of emission wavelength. The photoluminescence(PL) of Cu(Ⅰ)-based organometallic halides originates from multiple emission states, which are a metal-to-ligand charge transfer or a halide-to-ligand charge transfer(MLCT/HLCT)excited state and a cluster-centered(CC) excited state. MLCT/HLCT-related emission wavelength redshifts while CCrelated emission wavelength remains unchanged, indicating that the rearrangement of different emission states plays a critical role in the changes of luminescence wavelength. This study not only deepens the understanding of the influence of high pressure on(C_(12)H_(24)O_(6))_(2)Na_(2)(H_(2)O)_(3)Cu_(4)I_(6), but also provides valuable insights into the structure–property relationship of zero-dimensional Cu(Ⅰ)-based organometallic halides.

文摘The contamination of water resources by phenolic compounds(PCs)presents a significant environmental hazard,necessitating the development of novel materials and methodologies for effective mitigation.In this study,a metallic copper-doped zeolitic imidazolate framework was pyrolyzed and designated as CuNC-20 for the activation of peroxymonosulfate(PMS)to degrade phenol(PE).Cu-NC-20 could effectively address the issue of metal agglomeration while simultaneously diminishing copper dissolution during the activation of PMS reactions.The Cu-NC-20 catalyst exhibited a rapid degradation rate for PE across a broad pH range(3-9)and demonstrated high tolerance towards coexisting ions.According to scavenger experiments and electron paramagnetic resonance analysis,singlet oxygen(^(1)O_(2))and high-valent copperoxo(Cu(Ⅲ))were the predominant reactive oxygen species,indicating that the system was nonradicaldominated during the degradation process.The quantitative structure-activity relationship(QSAR)between the oxidation rate constants of various substituted phenols and Hammett constants was established.It indicated that the Cu-NC-20/PMS system had the optimal oxidation rate constant withσ^(-)correlation and exhibited a typical electrophilic reaction pattern.This study provides a comprehensive understanding of the heterogeneous activation process for the selective removal of phenolic compounds.

文摘The demand for neodymium(NdFeB) permanent magnets for electric vehicles and eco-friendly generators is increasing.However,NdFeB magnets contain rare earth elements(REEs),which are limited in supply.In this study,we performed an exchange reaction between magnesium halides(fluoride and chloride) and waste NdFeB scrap and then compared the characteristics of the extracted halides salts.The compositions of the ternary Mg fluoride(LiF:NaF:MgF_(2)=50:40:10 in mole ratio) and chloride(LiCl:NaCl:MgCl_(2)=10:50:40 in mole ratio) salts were thermodynamically determined for achieving low eutectic temperatures.The reactions between the NdFeB scrap powder(1-2 mm) and Mg halide salts were carried out at 1073 and 873 K for the fluoride and chloride systems,respectively,in an argon atmosphere.After the reaction,we separated Nd halide from the residual salt and evaluated the Ndextraction rate.The phase formation of the salt was analyzed using X-ray diffraction(XRD),and the extraction rate of Nd was analyzed using inductively coupled plasma optical emission spectroscopy(ICPOES).Nd was extracted in the form of Nd halide(NdF_(3) or NdCl_(3)),and the extraction rates in the fluoride and chloride systems are 98.64% and 84.59%,respectively.Thus,the fluoride system is more effective than the chloride system for Nd extraction.Our study provides a comprehensive comparative analysis of the effectiveness of fluo ride and chlo ride systems in extracting REEs from NdFeB magnet scrap.Our study findings can be used to develop an effective method for recycling magnet scraps.

文摘The crystallization of ionic crystals has traditionally been explained by Gibbs's classical nucleation theory.However,recent observations of intermediate phases during nucleation suggest that the process may be more complex,necessitating new theoretical frameworks,though key empirical evidence remains elusive.In this study,we used microdroplets to investigate the crystallization of sodium halides(NaCl,NaBr,and NaI)under homogeneous nucleation conditions across a wide range of supersaturations.In the evaporating droplet,NaCl follows the classical nucleation pathway,whereas NaBr and NaI exhibit the formation of an intermediate phase prior to the nucleation of anhydrous and hydrous single crystals,respectively.Optical and computational analyses indicate that these intermediate phases are liquid crystal phases composed of contact ion pairs.These findings establish a new theoretical framework for crystal nucleation and growth and offer methods to control nucleation pathways,enabling us to achieve desired crystals regardless of specific conditions.

文摘Low-dimensional lead-free metal halides have emerged as promising candidates for anti-counterfeiting applications,characterized by their low toxicity,diverse crystal structures,and exceptional optical properties.Conventional anti-counterfeiting technologies based on low-dimensional metal halides are often constrained by complex and time-consuming heating and solvent treatments that may insufficiently modify the luminescent characteristics of emitters,thus hindering their practical implementation in effective anti-counterfeiting strategies.In this study,we employ an innovative alloying strategy in low-dimensional zinc halides Cs_(2)ZnCl_(4) to enhance their luminescent performance.By introducing self-trapped exciton(STE)states through the alloying of Cu^(+)and Sb^(3+)ions in Cs_(2)ZnCl_(4),we achieve bright blue and red photoluminescence(PL)centered at 492 nm and 744 nm,respectively,under 266 nm excitation,with only red emission observed under 365 nm excitation.This approach enables instant and reliable anti-counterfeiting applications.This work presents new opportunities for developing robust anti-counterfeiting and information encryption/decryption technologies.

文摘Metal halide perovskites have emerged as highly promising candidates for the emissive layer in next-generation light-emitting diodes(LEDs)due to their narrow emission linewidths,high photoluminescence quantum yields,and tunable emission wavelengths.Achieving high-performance perovskite LEDs(Pe LEDs)requires the emissive layer to possess efficient radiative recombination,low defect density,minimal ion mobility,and effective carrier confinement.Perovskite/perovskite heterostructure(PPHS)offers a compelling approach for engineering emissive layers with these desired attributes,owing to their ability to passivate surface defects,tailor bandgaps,and suppress ion migration.Pe LEDs based on PPHS have demonstrated superior performance compared to single-phase devices,particularly in terms of external quantum efficiency and operational stability.This review provides a comprehensive overview of the typical PPHS architectures applied in Pe LEDs,including vertical,lateral,and bulk configurations.We discuss representative fabrication strategies and the associated optoelectronic properties of these heterostructures,highlighting the mechanisms by which they enhance device efficiency and stability.Finally,we explore the remaining challenges and prospects for the application of PPHS in Pe LEDs and other luminescent technologies.

文摘Halide perovskites have emerged as promising materials for X-ray detection with exceptional properties and reasonable costs.Among them,heterostructures between 3D perovskites and low-dimensional perovskites attract intensive studies of their advantages due to low-level ion migration and decent stability.However,there is still a lack of methods to precisely construct heterostructures and a fundamental understanding of their structure-dependent optoelectronic properties.Herein,a gas-phase method was developed to grow 2D perovskites directly on 3D perovskites with nanoscale accuracy.In addition,the larger steric hindrance of organic layers of 2D perovskites was proved to enable slower ion migration,which resulted in reduced trap states and better stability.Based on MAPbBr_(3)single crystals with the(PA)_(2)PbBr_(4)capping layer,the X-ray detector achieved a sensitivity of 22,245μC Gy_(air)^(−1)cm^(−2),a response speed of 240μs,and a dark current drift of 1.17.10^(–4)nA cm^(−1)s^(−1)V^(−1),which were among the highest reported for state-of-the-art perovskite-based X-ray detectors.This study presents a precise synthesis method to construct perovskite-based heterostructures.It also brings an in-depth understanding of the relationship between lattice structures and properties,which are beneficial for advancing high-performance and cost-effective X-ray detectors.
