摘要:
水系锌碘电池凭借锌、碘储量丰富、价格低廉、电池体系本征安全及较高的理论能量密度等优点，成为储能领域的研究热点。然而，其正负极在常用电解液(如ZnSO4、Zn(CF3SO3)2、ZnCl2等)体系中面临着一系列尚未解决的问题，如正极的多碘离子穿梭效应、活性碘的溶解，负极的锌枝晶、锌腐蚀及副反应等，这严重限制了水系锌碘电池的进一步发展。而向电解液中添加功能性添加剂有望同时缓解正负极的上述问题，且该操作简单，易于大规模工业化生产。因此，本文围绕水系锌碘电池电解液添加剂，系统阐述了水系锌碘电池在常用电解液体系中面临的关键挑战，综述了各类添加剂(大分子、有机添加剂、无机添加剂)的作用机理、功能、性质及其在水系锌碘电池中的性能表现。最后，对水系锌碘电池中电解液添加剂的未来发展方向进行了展望，以期为筛选和设计特定功能添加剂，实现高性能水系锌碘电池提供新思路。

摘要:
目前全球面临严峻的能源危机与环境污染问题，氢能作为一种清洁且具有高能量密度的能源载体，受到了广泛关注。电解水制氢因其能够将可再生电能转化为氢能，成为绿色制氢的主流技术。然而，电催化析氧反应和析氢反应存在较大的动力学能垒，且传统贵金属催化剂成本高、储量少，限制了其大规模应用。石墨烯凭借卓越的导电性、巨大的比表面积、优异的机械强度以及丰富的表面化学性质，在电催化领域展现出广阔的应用前景。本文系统梳理了石墨烯材料的制备技术及其在电解水制氢领域的应用。首先，本文通过“自上而下”和“自下而上”两大方法分析了石墨烯制备的优势与不足。在电解水催化剂中，石墨烯不仅凭借其高机械强度和良好的导电性发挥作用，还可通过缺陷工程和异原子掺杂等策略引入活性位点，用于构建高性能催化剂。此外，石墨烯凭借其特殊的结构和性能，在电解水小分子氧化、重水提纯、海水淡化及直接海水电解等耦合工艺中也起到了关键作用。本文进一步分析了石墨烯材料在电解水领域规模化应用中的主要挑战，重点聚焦于规模化制备、稳定性以及缺陷控制等问题，并对其未来发展提出了见解。

摘要:
Novel adsorbents for efficient natural gas purification should strike a balance between high selective adsorption performance and moderate adsorption enthalpy. To develop such materials, herein, a novel (3,6)-c topological metal-organic framework (MOF) featuring terminal coordinated acetate was constructed from [Fe3(μ3-O)(acetate)2(carboxyl)4(pyridyl)2] cluster and 5-(pyridin-4-yl)isophthalic acid, yielding [Fe2ⅢFeⅡ(μ3-O)(acetate)2(L)2(H2O)]·xGuest (designated as NJTU-Bai89; NJTU-Bai stands for Nanjing Tech University Bai′s group). The methyl group of acetate is impendent in the 1D pore channel, dividing it into the gourd-shaped one. Interestingly, NJTU-Bai89 exhibited high low-pressure C3H8 uptake and moderate adsorption enthalpy, owing to effective synergy between a suitable pore size and accessible nonpolar pore surfaces.

摘要:
Two zero-dimensional inorganic-organic hybrids, (NMe3CH2Ph)2[Zn(H2O)6](SO4)2 (1) and (NMe3CH2Ph)4[Zn2Cl2(SO4)3] (2), were assembled from ZnSO4 and trimethylbenzylammonium chloride. Both feature an inorganic-organic sandwich structure with organic layers formed via aromatic stacking. 1 contains a {[Zn(H2O)6](SO4)2}2- hydrogen-bonded network, while 2 consists of binuclear zinc clusters. Both exhibited room-temperature phosphorescence. 1 showed a lifetime of 14.00 ms (invisible), whereas 2 displayed a lifetime of 290.00 ms with visible green afterglow. Furthermore, a series of host-guest doped afterglow materials was developed using compound 1 as the host matrix. Tuning the guest molecules enabled afterglow tuning from cyan to orange-yellow, with lifetimes enhanced up to about 65-fold versus the pristine host. Furthermore, the application of the doped systems in advanced anti-counterfeiting was preliminarily explored.

摘要:
A tetranuclear Ho(Ⅲ)-based complex [Ho4(L)2(dbm)6(CH3O)4] (1) was synthesized via solvothermal methods, where HL=(E)-2-hydroxy-3-methoxy-N′-[(6-methoxypyridin-2-yl)methylene]benzohydrazide and Hdbm=dibenzoylmethane. Structural characterization revealed that this complex is composed of four Ho3+ ions, six dbm- ions, two L- ions, and four coordinated CH3O- ions. The interaction mechanisms between ligand HL, 1 and calf thymus DNA (CT-DNA) were investigated by using UV-Vis spectroscopy, fluorescence titration, and cyclic voltammetry. The results indicated that 1 can interact with DNA via intercalation. Catalytic tests showed that 1 exhibits remarkable catalytic activity, capable of catalyzing the cycloaddition reaction of CO2 with epoxides and the Knoevenagel condensation reaction between malononitrile and aldehydes.

摘要:
A series of MIL-101(Fe)/Cu2O heterojunction photocatalysts was successfully constructed by coupling highly active dodecahedral Cu2O with MIL-101(Fe) through a co-precipitation method. The catalytic performance of these materials was systematically evaluated under visible light using tetracycline as the target pollutant. The results indicated that when the mass fraction of MIL-101(Fe) was 20%, the composite material exhibited the best catalytic performance, with a tetracycline degradation rate of up to 87.37% after 100 min of illumination, significantly enhancing the photocatalytic degradation efficiency. The significant improvement in photocatalytic performance was mainly attributed to the tight interface coupling between the two components. Transient photocurrent response and electrochemical impedance spectroscopy (EIS) demonstrated that the introduction of MIL-101(Fe) greatly enhanced the electron conduction ability of the composite system and accelerated charge migration. On the other hand, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), UV-Visible diffuse reflectance spectra (UV-Vis DRS), and Mott-Schottky characterizations, combined with electron paramagnetic resonance (EPR) tests, confirmed the formation of an effective Z-scheme heterojunction between the two components. This Z-scheme heterojunction photocatalyst not only promotes the spatial separation of photogenerated electron-hole pairs but also retains the stronger redox ability of the composite material, thereby synergistically achieving efficient degradation of pollutants.

摘要:
采用电沉积和浸渍电还原法制备了负载Au、Pt纳米粒子的镍铁层状双金属氢氧化物(NiFe-LDH)催化剂(AuPt-NiFe-LDH-NF，NF为泡沫镍)并用于电解水析氢反应(HER)。该催化剂仅需17 mV的过电位便可达到10 mA·cm-2的电流密度，性能优于商用Pt/C电极。原位电化学阻抗谱(EIS)结果表明，负载Pt之后NiFe-LDH-NF的电荷转移能力提高，HER中的Volmer步骤显著加快。强电负性的Au可与界面水构建氢键网络，稳定Pt表面的吸附水中间体，并通过Grotthuss机制加速水分解产生的OH-向界面的转移，使HER的氢吸附和界面电荷转移速率增加。所制备电极与GaInP2/GaInAs/Ge太阳能电池构建的光伏-电解水(PV-EC)器件实现了17.2%的太阳能到氢能转化效率。

针对单一电化学反应体系中活性组分利用效率受限的问题，构建了泡沫Ti/FeCo-Fe2O3-CoFe2O4/SnO2-Sb(简称为Ti/ FeCoO/SnO2-Sb)复合阳极与过氧单硫酸盐(PMS)协同作用的电化学活化体系(Ti/FeCoO/SnO2-Sb+PMS)。为突破传统SnO2-Sb阳极在界面反应动力学与服役稳定性方面的固有瓶颈，提出以FeCoO作为关键中间层与SnO2-Sb构筑分级复合电极的策略。借助Fe、Co双金属位点的协同效应重构电极界面微环境，从而实现PMS活化效率与体系稳定性的同步提升。性能评估结果表明，在Ti/FeCoO/SnO2-Sb+PMS体系中，Ti/FeCoO/SnO2-Sb对甲基橙(MO)表现出最优的去除能力与矿化水平，其化学需氧量(COD)去除率显著高于对照体系；同时，酸性条件更有利于PMS活化，从而进一步强化了MO的降解动力学性能。相较于未添加FeCoO体系(Ti/SnO2-Sb+PMS)，Ti/FeCoO/SnO2-Sb+PMS复合体系展现出更为突出的整体性能优势。在此基础上，结合电化学表征、电子顺磁共振(EPR)与密度泛函理论(DFT)计算对机理进行解析，结果表明，性能提升主要归因于复合界面有效促进了直接电子转移(DET)过程并强化了PMS的电化学活化；反应过程中，超氧阴离子自由基(·O2-)、羟基自由基(·OH)、硫酸根自由基(SO4·-)和单线态氧(1O2)协同作用，实现了MO共轭结构的高效破坏与持续深度氧化。

摘要:
采用静电纺丝技术制备了多孔氮掺杂碳纳米纤维(PNCNFs)，随后通过高温碳化及还原处理，成功合成了一系列PNCNFs锚定PtRu合金材料(PtRu/PNCNFs)。碳纳米纤维中氮的掺杂引入了大量的亲水性基团，能够显著增强材料与电解液之间的润湿性，有助于离子传输和整体电化学性能的进一步改善；同时PNCNFs具有较大的比表面积，PtRu合金的存在从一定程度上增加了其活性位点。此外，高温下形成的多孔结构使得PtRu合金能够均匀分散在材料表面，有利于调节材料的电子结构，促进电子转移，提升析氢反应(HER)性能。结果显示，经过500 ℃处理的PNCNFs(PtRu/PNCNFs-500)在1 mol·L-1 KOH和含1 mol·L-1 KOH的海水溶液中均表现出优异的HER性能。在电流密度为10 mA·cm-2时，PtRu/PNCNFs-500的析氢过电位分别为15.8和18.3 mV，塔菲尔(Tafel)斜率分别为20.58和20.65 mV·dec-1，性能显著优于经300、400和600 ℃处理的PNCNFs，并均展现出良好的HER稳定性。

摘要:
Herein, ratiometric fluorescence-based carbon dots (N-CDs) with blue emission were prepared by using simple one-step hydrothermal methods from benzimidazole and L-tryptophan as precursors. Dual emission peaks were observed at 356 and 442 nm under the excitation wavelength of 303 nm. Upon addition of sulfide ions (S2-), the fluorescence intensity at 442 nm decreased significantly, while that at 356 nm increased. The F442/F356 intensity ratio (where F356 and F442 refer to the fluorescence intensity at 356 and 442 nm, respectively) exhibited a linear relationship with the concentration of S2- (0-60.0 μmol·L-1), and the detection limit was determined to be 0.076 μmol·L-1. The fluorescence detection mechanism was ascribed to the static quenching effect. Furthermore, this fluorescence probe was successfully used for the determination of S2- in real samples with satisfactory recoveries. Finally, the analytical greenness metric for sample preparation (AGREEprep) and blue applicability grade index (BAGI) tools indicated the high sustainability of this platform.

摘要:
To enhance the low-temperature activity and anti-sintering performance of Ni-based catalysts for CO methanation, mesoporous CeO2 supports with a confined structure were synthesized via a hydrothermal method. The effects of three Ni loading methods—incipient wetness impregnation, co-precipitation, and bis(cyclopentadienyl)nickel sublimation—on catalytic performance were systematically compared. Characterization techniques, including X-ray diffraction (XRD), N2 adsorption-desorption test, hydrogen temperature-programmed reduction (H2-TPR), X-ray photoelectron spectroscopy (XPS), and transmission electron microscopy (TEM), revealed the critical influence of the loading method on Ni species dispersion, particle size, and metal-support interaction. The results indicated that all three mesoporous Ni/CeO2 catalysts exhibited excellent anti-sintering properties due to the confinement effect of the support. However, their low-temperature activities differed significantly, primarily determined by the specific state of Ni. In the NC-B catalyst prepared by bis(cyclopentadienyl)nickel sublimation, the interaction between Ni species and the support was relatively weak. After reduction, this method yielded highly dispersed metallic Ni nanoparticles, increasing the number of low-temperature active sites. Consequently, the NC-B catalyst achieved 98% CO conversion rate and 100% CH4 selectivity at 300 ℃, demonstrating the optimal low-temperature methanation performance.

摘要:
In this work, by using diphenylphosphonic acid as ligand and butyltin hydroxide oxide as tin source, reacting with nickel acetate and cobalt acetate respectively, two hexanuclear tin oxo clusters formulated as [(n-BuSn)4 Ni2(μ3-O)2(μ3-OH)2(CH3COO)4(Ph2PO2)6] (1) and [(n-BuSn)4Co2(μ3-O)2(μ3-OH)2(CH3COO)4(Ph2PO2)6] (2) were solvothermally synthesized. Both 1 and 2 were characterized by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction. Spectral experiments revealed that the two complexes have absorptions in the visible region. The optical band gaps for complexes 1 and 2 are 1.90 and 1.79 eV, respectively. Complexes 1 and 2 exhibited photocatalytic CO2 reduction activity, and only CO was generated, with rates of 10.01 and 26.89 μmol·g-1·h-1, respectively. CCDC: 2505024, 1; 2505025, 2.

摘要:
Two complexes [Cd(L)(CH3O)(CH3COO)]·CH3OH·(CH3)2NH (C1) and [Mn(L)Cl2(CH3OH)] (C2) were synthesized by reacting a new imidazole-bearing ligand 4-(1H-imidazol-1-yl)-N′-(pyridin-2-ylmethylene)benzohydrazide (L) with cadmium and manganese salts, respectively. The ligand was characterized by 1H NMR and 13C NMR spectroscopy, while the complexes were analyzed by single-crystal X-ray diffraction, powder X-ray diffraction, thermogravimetric analyses, and UV-Vis spectroscopy. Complex C1 features a 1D zigzag chain structure formed by alternating connections of one ligand and one metal ion. In contrast, complex C2 exhibits a mononuclear molecular structure, where each unit consists of one ligand connected to one manganese ion. Both complexes further form a 3D structure through π-π interactions and intermolecular hydrogen bonds. Cell proliferation assays conducted on four tumor cell lines and one normal cell line revealed that both C1 and C2 exhibited significantly stronger inhibition of tumor cell growth compared to the ligand L. Notably, C1 demonstrated superior anti-proliferative activity against A549 and A2780 cells relative to cisplatin, while showing comparable cytotoxicity toward SMMC-7721 cells. Further mechanistic studies indicated that C1 induces apoptosis in both SMMC-7721 and A549 tumor cells, suppresses the invasion and migration of SMMC-7721 cells, and arrests the cell cycle at the G0/G1 phase.

摘要:
Three zinc(Ⅱ) and cadmium(Ⅱ) coordination polymers, namely [Zn(μ-cada)(bipy)(H2O)]n (1), [Zn(μ3-cada)(phen)·H2O]n (2), and [Cd(μ3-cada)(phen)]n (3), have been constructed hydrothermally at 160 ℃ using bis(4-carboxyphenyl)urea (H2cada), 2, 2′-bipyridine (bipy)/1, 10-phenanthroline (phen), and zinc and cadmium chlorides. The three complexes were fully characterized by infrared spectroscopy, element analysis, thermogravimetric analysis, and single-crystal X-ray diffraction. Single-crystal X-ray diffraction analysis indicates that complexes 1-3 form crystals in the monoclinic P21/n, monoclinic I2/a, and orthorhombic Pbcn space groups. These complexes all possess different 1D chain structures. Complexes 1 and 2 demonstrate substantial catalytic efficiency in the Knoevenagel condensation under ambient temperature conditions.

摘要:
To investigate the antitumor properties of copper(Ⅱ) complexes, a series of Cu(Ⅱ) complexes (C1-C3) derived from 6, 7-dihydro-5H-quinoline-8-one thiosemicarbazone ligands was designed and synthesized. These complexes exhibited significantly higher potency in inhibiting tumor cell growth in vitro compared to cisplatin. Among them, C3 had the highest antitumor activity against MDA-MB-231 cells, with a half maximal inhibitory concentration (IC50) value of 1.42 μmol·L-1. Moreover, C3 effectively inhibited the growth of 3D multicellular spheres. Mechanistically, it induced significant reactive oxygen species (ROS) generation, initiating a dual-pathway cytotoxic effect. On the one hand, it triggers endoplasmic reticulum stress and inhibits the activity of the related protein, protein disulfide isomerase (PDI). On the other hand, it induces mitochondrial dysfunction. These combined stresses ultimately lead to the apoptosis of MDA-MB-231 cells.

摘要:
To develop highly stable and active Ru complex catalysts for CO2 hydrogenation, we synthesized Ru complexes bearing rigid pincer-type tridentate NNN (pyrazole-pyridine-pyrazole) ligands and weakly coordinated triphenylphosphine (PPh3) ligands. The NNN ligands can strongly chelate with the Ru metal center, contributing to the overall robustness of the catalytic system. Meanwhile, PPh3 can easily dissociate to form vacant coordination sites, thereby enhancing catalytic activity. As a result, the Ru(Ⅱ)-NNN complex [Ru(L-NNN)Cl(PPh3)2]Cl (1, L-NNN=2,6-bis(5-methyl-1H-pyrazol-3-yl)pyridine) was not only quite stable, but also showed high activity for CO2 hydrogenation to formate, achieving a TON of up to 150 000. In the mechanism study, based on the results of in-situ NMR, in-situ HPLC-HRMS spectra, and density functional theory calculations, it is speculated that the active intermediates with empty coordination sites are highly active species in CO2 hydrogenation.

摘要:
Bi2O3@BiVO4 composites were synthesized using the solvothermal method with ethylene glycol as the solvent. Bi2O3 was grown on the surface of BiVO4 by regulating the reaction temperature. The adsorption performance of the composite for rhodamine B (RhB) was investigated. The results indicate that the reaction temperature significantly impacts the morphology and adsorption performance of Bi2O3@BiVO4. The Bi2O3@BiVO4 composite prepared at 180 ℃ (180-BO@BVO) consisted of nanoparticles with an average size of 7 nm, featuring a higher concentration of oxygen vacancies on the surface, but with a lower specific surface area (only 1.2 m2·g-1). 180-BO@BVO, with oxygen species adsorbed at surface oxygen vacancies carrying a negative charge, achieved an impressive RhB removal efficiency of up to 83.0% through electrostatic interaction with RhB. The adsorption process follows the Langmuir isotherm and the pseudo-second-order kinetic model, suggesting that it is predominantly governed by chemical adsorption. After five cycles of adsorption experiments, the removal efficiency of RhB by composites remained basically unchanged (more than 80%), demonstrating excellent regeneration performance.

摘要:
To address the challenges of poor solubility and difficult recyclability of powdered metal-organic frameworks (MOFs), a Eu-based MOF complex, [EuNa(L)(H2O)3]·2H2O (Eu/Na-MOF), was synthesized by the hydrothermal method using 3,5-bis(3,5-dicarboxyphenyl)-1H-1,2,4-triazole (H4L) as the ligand in this study. Systematic characterization and performance evaluation revealed that the complex exhibits a unique 3D structure, high phase purity, excellent thermal stability, and outstanding luminescent properties. Furthermore, the complex was encapsulated in poly(methyl methacrylate) (PMMA) to fabricate a flexible and water-washable composite fluorescent film (Eu/Na-MOF/PMMA). Based on static and dynamic quenching mechanisms, respectively, the film enables reversible detection of tryptamine and Cr2O72- ions in aqueous solutions, demonstrating high selectivity, stability, and portability.
