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 ：
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 ：
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 ：
Potential health risks related to environmental endocrine disruptors (EEDs) have aroused research hotspots at the forefront of water treatment technologies. Herein, nitrogen-doped titanium dioxide/schwertmannite nanocomposites (N-TiO2 /SCH) have been successfully developed 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 degradation 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 (center dot OH) and singlet oxygen (1 O2 ). 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 catalysts, but also lays a theoretical foundation for the potential application of mineral-based materials in wastewater treatment.

Abstract ：
Perovskite solar cells (PSCs) fabricated of TiO2 electron transporting material (ETM) have aroused tremendous attention, but their power conversion efficiency (PCE) needs further improvements. In this study, for the first time, zirconium (Zr)-doped brookite TiO2 nanorods (ZTO) are synthesized by a facile route and subsequently employed as an ETM in PSCs which finally achieves a considerable PCE of 19.42 % by optimizing all operating conditions. Further characterizations have been undertaken to explore in detail the effects of Zr doping on the nature of the perovskite active layer and the photovoltaic performance. As a consequence, the enhanced PCE can be ascribed to the high quality perovskite crystals and a more favorable energy level alignment between the perovskite layer and ZTO mesoporous layer.

Abstract ：
Hydrogen-bonded organic frameworks (HOFs) hold significant promise for catalytic applications. However, the collapse of pores upon solvent removal significantly restricts the utility of HOFs in photocatalytic processes for energy production and storage. This work describes HOF-based catalysis with a stable pore structure and efficient catalytic activity that has been designed and tested for CO2 photo-reduction in pure water. In this system, based on HOFs, the 1,3,6,8-tetra(4-carboxyphenyl)pyrene (H4TBAPy) molecules segment the large pore spaces into multiple domains. These molecules, anchored to the HOF via strong CH⋯π interactions, act as rigid auxiliary linkers, notably improving the structural stability within the HOF. Additionally, the incorporation of electron-rich H4TBAPy molecules expedited electron transport within the HOF, markedly enhancing its catalytic activity. This work provides a new strategy for designing stable and high-performance HOF photocatalysts. (Figure presented.) © Science China Press 2024.

Abstract ：
The Li-S battery has garnered widespread attention as an intriguing new energy storage equipment due to its remarkable energy density and low cost. Nevertheless, the infamous shuttle effect seriously hinders the commercialization process. In order to address this issue, this study rationally synthesizes the composites comprising Keggin-type polyoxometalate and Co nanoparticles, which are then coated on a pristine polypropylene separator. The modified separator can greatly inhibit lithium polysulfide shuttling, thereby leading to a greatly improved electrochemical performance. At the first cycle, the fabricated Li-S battery exhibits a specific discharge capacity of 1335.7 mA h g(-1), surpassing the 938.7 mA h g(-1) capacity of an unmodified separator. At a current density of 1C, the initial reversible discharge capacity reaches 988.2 mA h g(-1), and even after 500 cycles, it still retains a remaining capacity of 664.2 mA h g(-1), with a capacity decay rate of 0.066% per cycle. Even at a high sulfur loading of 4.2 mg cm(-2), the device displays a remarkable initial discharge capacity of 1158.2 mA h g(-1), with a remaining capacity of 952.7 mA h g(-1) after 70 cycles (0.1C). This significant performance enhancement could be ascribed to the synergistic effect of PMo12/Co-NCe, which exhibits greatly decreased electron transfer resistance and contact angle to the electrolyte, facilitating the rapid transport of Li-ion and kinetics. Meanwhile, the severe shuttle effect is alleviated effectively by combining the strong catalytic activity of PMo12 and Co nanoparticles with long-chain polysulfides.

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 ：
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.
