Abstract ：
Potential health risks related to environmental endocrine disruptors(EEDs)have aroused re-search hotspots at the forefront of water treatment technologies.Herein,nitrogen-doped ti-tanium dioxide/schwertmannite nanocomposites(N-TiO2/SCH)have been successfully de-veloped as heterogeneous catalysts for the degradation of typical EEDs via photo-Fenton processes.Due to the sustainable Fe(Ⅲ)/Fe(Ⅱ)conversion induced by photoelectrons,as-prepared N-TiO2/SCH nanocomposites exhibit much enhanced efficiency for the degrada-tion of bisphenol A(BPA;ca.100％within 60 min under visible irradiation)in a wide pH range of 3.0-7.8,which is significantly higher than that of the pristine schwertmannite(ca.74.5％)or N-TiO2(ca.10.8％).In this photo-Fenton system,the efficient degradation of BPA is mainly attributed to the oxidation by hydroxyl radical(·OH)and singlet oxygen(1O2).Moreover,the possible catalytic mechanisms and reaction pathway of BPA degradation are systematically investigated based on analytical and photoelectrochemical analyses.This work not only provides a feasible means for the development of novel heterogeneous photo-Fenton cat-alysts,but also lays a theoretical foundation for the potential application of mineral-based materials in wastewater treatment.

Abstract ：
Superior quality of perovskite film with perfect crystalline and low defect density is crucial for achieving excellent photovoltaic performance and durability of perovskite solar cells (PSCs), and regulation of growth of perovskite crystal and defects passivation by additive is remain challenge. Herein, two acyl molecules (Succinimide: SCI, and Hydantoin: HDT) were incorporated into perovskite precursor solution as additive. It can be found that the HDT molecule can not only passivate undercoordinated Pb 2+ defects in perovskite films by the -C=O groups with coordination bonds, but also formed hydrogen bonds with I - by -NH- group, which effectively inhibited the formation of iodine vacancy defects and regulated growth rate of perovskite crystals, and the quality of perovskite films was optimized with enlarging grain size and reduced trap -density. Consequently, power conversion efficiency of HDT-based device was enhanced from 19.47 % to 21.00 %, with an enhancement of J SC and V OC . Moreover, the HDT-based device without encapsulation retained 83.7 % of its initial PCE after being aged at 10 - 20 % RH for 60 days. Obviously, such a study could provide a new strategy to optimize quality of perovskite film for boosting performance of PSCs.

Abstract ：
Sulfate crystals are often criticized for their low birefringence. The small anisotropic SO4 group is becoming the biggest bottleneck hindering the application of sulfates in optical functional materials. In this study, we report a new method to significantly enhance the birefringence of sulfates. The title compound increases the birefringence recording of sulfates to 0.542@546 nm, which is significantly larger than that of the commercial birefringent crystal of TiO2 (0.306@546.1 nm). At the infrared wavelength, the birefringence of Hg-4(Te2O5)(SO4) can be up to 0.400@1064 nm, which is also much larger than the infrared birefringent crystal of YVO4 (0.209@1064 nm). In addition, it also has a wide transparency range, high thermal stability, and excellent environmental stability, making it a potential birefringent material. Hg-4(Te2O5)(SO4) features a novel two-dimensional layered structure composed of [Hg-4(Te2O5)](2+) layers separated by isolated (SO4)(2-) tetrahedra. This compound was designed by introducing a highly selective cation in a tellurite sulfate system. The low valence low coordination cations connect with tellurite groups only, making the sulfate isolated in the structure. The steric repulsive action of the isolated SO4 tetrahedra may regulate the linear and lone pair groups arranged in a way that favors large birefringence. This method can be proven by theoretical calculations. PAWED studies showed that the large birefringence originated from the synergistic effect of (Hg2O2)(2-), (Te2O5)(2-), and (SO4)(2-) units, with a contribution ratio of 42.17, 37.92, and 19.88%, respectively. Our work breaks the limitation of low birefringence in sulfates and opens up new possibilities for their application as birefringent crystals.

Abstract ：
It is of great difficulty to create a new antimonite with second-harmonic-generation (SHG) intensity larger than 6 times that of KDP. In this study, a polyfluoroantimonite strategy has been proposed to explore fluoroantimonites with large nonlinear optical (NLO) coefficients. Under the cooperation of chemical (highly asymmetric pi-conjugated organic amine) and physical (viscous reaction medium ethylene glycol) methods, two novel polyfluoroantimonites, namely, (3PC)(2)(Sb4F14) and (3AP)(2)(Sb4F13), have been achieved. Interestingly, these two structures contain two new polyfluoroantimonite groups respectively, an isolated (Sb4F14)(2-) four-member polyhedral ring and an infinite [Sb4F13](infinity)(-) helical chain. More importantly, the polar (3AP)(2)(Sb4F13) displays a strong SHG intensity of 8.1 x KDP, a large birefringence of 0.258@546 nm and a high laser-induced damage threshold (LIDT) value of 149.7 MW cm(-2). Theoretical calculations indicated that its strong SHG effect stems from the synergistic effect of the helical [Sb4F13](infinity)(-) polyfluoroantimonite chain and pi-conjugated 3AP(+) cation, with a contribution ratio of 48.93% and 50.77% respectively. This work provides a new approach for the design and synthesis of high-performance fluoroantimonites.

Abstract ：
The first examples of alkali metal selenite sulfates, namely, Na-8(SeO3)(SO4)(3) (1), Na-2(H2SeO3)(SO4) (2), and K-4(H2SeO3)(HSO4)(2)(SO4) (3), were successfully synthesized by hydrothermal reactions. Their structures display three different zero-dimensional configurations composed of isolated sulfate tetrahedra and selenite groups separated by alkali metals. Na-8(SeO3)(SO4)(3) (1) features a noncentrosymmetric structure, while Na-2(H2SeO3)(SO4) (2) and K-4(H2SeO3)(HSO4)(2)(SO4) (3) are centrosymmetric. Powder second-harmonic-generation measurements revealed that Na-8(SeO3)(SO4)(3) (1) shows a phase-matchable SHG intensity about 1.2 times that of KDP. UV-vis-NIR diffuse reflectance spectroscopic analysis indicated that Na-8(SeO3)(SO4)(3) (1) has a short UV cutoff edge and a large optical band gap, which makes it a possible UV nonlinear optical material. Theoretical calculations revealed that the birefringence of Na-8(SeO3)(SO4)(3) (1) is 0.041 at 532 nm, which is suitable for phase-matching condition. This work provides a good experimental foundation for the exploration of new UV nonlinear crystals in an alkali metal selenite sulfate system.

Abstract ：
Spiro-OMeTAD, as a crucial component of hole-transporting layer (HTL), exhibits limited mobility and conductivity, and the lithium bis-trifluoromethanesulfonimide dopant is sensitive to water vapor, which imposes restrictions on the photovoltaic properties of perovskite solar cells (PSCs). Herein, the iron-porphyrin (FePP) is introduced into Spiro-OMeTAD solution as additive, which facilitates the oxidation process of Spiro-OMeTAD, leading to the enhancement of hole mobility and hole extraction and transport. Besides, the surface Pb2+ defects of perovskite film are cured by the presence of carboxylic acids (-COOH) in FePP. As a result, the photovoltaic properties of PSCs with FePP additive have been improved with a power conversion efficiency (PCE) of 21.58%. Moreover, FePP can further anchor Li+ ions in HTL to prevent it from being invaded by water vapor. Dramatically, the degradation of unencapsulated devices with FePP is suppressed significantly, which retains 82.0% of its original PCE under 10-20% relative humidity (RH) after 7100 h and maintains about 79.6% of its original PCE under 50-60% RH after 1000 h. Thus, this study shows that the design and development of multifunctional HTL additives holds great potential for achieving highly efficient and durable PSCs. The iron-porphyrin additive can not only promote the oxidation of Spiro-OMeTAD and improve the extraction and transport of holes of HTL, but also passivate the Pb2+ defects of perovskite film and prevent the Li+ from being invaded by water vapor, which enhance the power conversion efficiency and stability of perovskite solar cells significantly.image (c) 2024 WILEY-VCH GmbH

Abstract ：
The optimization of interfacial properties between the perovskite layer and the electron-transporting layer (ETL) is always a vital approach to reduce the defects for improving the photovoltaic performance of the perovskite solar cells (PSCs). Herein, nanomaterials of tunable photoluminescent nitrogen-doped graphene quantum dots (TP-N-GQDs) were prepared though a facile solid-phase microwave-assisted (SPMA) method in the presence of citric acid by adding urea as a nitrogen precursor. Leveraging the synergistic effect of N-GQDs along with the tunable photoluminescent property at the interface of PSCs proved to be an efficient strategy for enhancing the light-harvesting capability and facilitating the charge transportation simultaneously, which leads to an overall improvement of the PSC performance. Moreover, the electron-rich pyridinic nitrogen within TP-N-GQDs acted as a Lewis base, coordinating with Pb2+ ions in perovskite and forming coordination bonds by sharing electron pairs, thereby decreasing the density of defects at the interface and the nonradiative recombination of the photogenerated carriers. Consequently, through the optimization of the nitrogen doping ratio of TP-N-GQDs, PSCs with areas of 0.09 and 1 cm(2) achieved maximum power conversion efficiencies (PCEs) of 21.98 and 17.12%, respectively. Additionally, TP-N-GQD passivation significantly enhanced the long-term stability of the device. The unencapsulated TP-N-GQD-modified device could sustain about 83% of its initial PCE afterward for 30 days of storage in air (25 +/- 5 degrees C, RH 25 +/- 5%).

Abstract ：
The migration and volatilization of cations within organic-inorganic hybrid perovskite (OIPs) materials has been identified as a major issue for irreversibly degrading perovskite solar cells (PSCs), severely limiting their performance and impeding progress toward large-scale applications. To mitigate these problems, an adjustable cation immobilization strategy was proposed for the first time, in which a series of fluorobenzenesulfonamide (FBSA) molecules was introduced into perovskite precursor, a strong coordination bond was formed between the sulfonamide group with the octahedral imperfection caused by iodine vacancy, along with a hydrogen bond formed between the cation and F atom. As a result, the A-site cations were tightly immobilized in the octahedral of perovskite crystal lattice and the uncoordinated Pb2+ defects were effectively eliminated. Besides, the immobilization distance of cation was finely optimized by changing the substitution position of F atoms. Based on the cation-immobilized perovskite film, the efficiency of PSCs was significantly increased from 19.88 % to 22.30 %. Moreover, the unencapsulated PSCs exhibited impressive light and thermal stability, retaining 82 % of the initial efficiency after 720 h illumination at 1-sun, and maintaining nearly 80 % of the initial PCE after heating at 85 degrees C for 240 h. Thus, the present study offers a promising approach for advancing the commercialization of stable and high-efficiency perovskite solar cells.

Abstract ：
Pesticides and its degradation products,being well-known residues in soil,have recently been detected in many water bodies as pollutants of emerging concerns,and thus there is a contemporary demand to develop viable and cost-effective techniques for the removal of related organic pollutants in aqueous phases.Herein,a visible-light-responsive Fenton system was constructed with iron-doped bismuth oxybromides(Fe-BiOBr)as the catalysts.Taking the advantage of sustainable Fe(Ⅲ)/Fe(Ⅱ)conversion and optimized H2O2 utilization,the optimal Fe-BiOBr-2 catalyst showed an excellent atrazine removal efficiency of 97.61％in 120 min,which is superior than the traditional homogeneous Fenton and the majority of heterogeneous processes documented in the literature.In this photo-Fenton system,hy-droxyl(·OH)and superoxide(·O2-)radicals were dominant active species contributed to the oxidative degradation of atrazine.Due to the production of various active radicals,five degra-dation pathways were proposed based on the identification of intermediates and degrada-tion products.Overall,this work not only demonstrates a fundamental insight into creating highly efficient and atom economic photo-Fenton systems,but also provides a complemen-tary strategy for the treatment of organic pollutants in water.

Abstract ：
Silicon-based anodes heavily depend on the binder to preserve the unbroken electrode structure. In the present work, natural flaxseed gum (FG) is used as a binder of silicon nanoparticles (SiNPs) anode for the first time. Owing to a large number of polar groups and a rich branched structure, this material not only anchors tightly to the surface of SiNPs through bonding interactions but also formed a hydrogen bonding network structure among molecules. As a result, the FG binder can endow the silicon electrode with stable interfacial adhesion and outstanding mechanical properties. In addition, FG with a high viscosity facilitates the homogeneous dispersion of the electrode components. When FG is used as a binder, the cycling performance of the Si anode is greatly improved. After one hundred cycles at an applied current density of 1 A g-1, the electrode continues to display remarkable electrochemical properties with a significant cyclic capacity (2213 mA h g-1) and initial Coulombic efficiency (ICE) of 89.7%. FG is used as a silicon-based anode binder for lithium-ion batteries for the first time. As FG possesses abundant polar groups and branched chains, it enhances the mechanical properties of the silicon electrode and greatly improves the cycling stability of the silicon electrode. image
