Driven by the progress of sustainable development, environmental remediation and water treatment have become increasingly important. Photocatalysis, capable of degrading pollutants through light (especially visible light) irradiation, has received widespread research attention. Titanium dioxide(TiO2) is a promising photocatalyst, yet its practical use is limited by low visible-light utilization and rapid photogenerated charge recombination. Herein, an S-scheme TiO2-WO3(Tungsten trioxide) heterojunction was successfully fabricated; the difference in Fermi levels induces a built-in electric field directed from TiO2to WO3, which thus constructs the S-scheme heterojunction. The as-prepared heterojunction exhibits a markedly enhanced transient photocurrent density, with the carrier lifetime prolonged from 2.69 ns to 41.61 ns. Under visible-light irradiation, the heterojunction achieves a methylene blue (MB) removal efficiency of over 95% within 90 min, and its pseudo-first-order kinetic rate constantkreaches 0.032 min−1, which is approximately 16 times that of pure TiO2. Radical trapping experiments confirm that the dominant active species responsible for the catalytic process are photogenerated holes and the hydroxyl radicals derived therefrom.

A CdS-WO 3 S-scheme heterojunction material modified by CQDs was constructed through simple methods, which effectively increases the photocatalytic degradation rate of single CdS. In the composite material, CdS acts as a reducing photocatalyst (RP) and WO 3 acts as an oxidizing photocatalyst (OP), forming an S-scheme heterojunction. In order to solve the photocorrosion problem of CdS, carbon quantum dots (CQDs) were loaded onto CdS. The CQDs possess a high work function, enabling them to facilitate electron transfer, enhance the migration of photogenerated carriers, and suppress electron-hole pair recombination, thus improving photocatalytic performance. The characterizations of XRD, TEM, element mapping, and XPS confirmed the successful synthesis of the CQDs-CdS-WO 3 composite. The material not only exhibited a photocatalytic degradation efficiency of 89.7% and 58.8% towards norfloxacin and tetracycline, respectively, but also revealed a certain degradation capability toward methylene blue and methyl orange. The primary active substances relevant in this degradation process are h + , 1 O 2 , H 2 O 2 , • O 2 − , and • OH. After multiple cyclic experiments, the material still maintains stable crystalline structure and degradation activity. Therefore, the successful preparation of this composite material provides a new method for photocatalytic decomposition of antibiotics and organic dyes.

Coating the charged aromatic polymers on ultrafiltration membranes is a feasible strategy to fabricate antifouling nanofiltration (NF) membranes. However, these NF membranes haven’t achieved high rejection and also are very limited because such polymers should be soluble in commonly polar solvents. Sulfonated poly(arylene ether ketone)s (sPAEKs) generally show poor solubility in commonly polar solvents due to their rigid polymer backbones, thus they could not be employed as the coating materials of NF membranes at present. Herein, the soluble sPAEKs in commonly polar solvents are synthesized by attaching methyl side groups to their polymer backbones. Accordingly, these sPAEKs could be coated on ultrafiltration membranes to prepare the antifouling NF membranes. Moreover, the Lewis acid-base interactions between the carbonyl and cation of the sPAEKs coating layer could improve rejection. Besides, their hydrophilic sPAEKs coating layer is favorable for improving permeability. Therefore, the sPAEKs coating layer endows the as-made membrane with excellent nanofiltration performances, such as an antibiotic rejection of 98%, a flux of 31.8 LMH/bar, an antibiotic/NaCl selectivity of 43.6, and a flux recovery rate of 98% for the foulant of bovine serum albumin. It still showed excellent resistance to chlorine oxidation because of the aromatic backbone of the sPAEKs coating layer. This fabrication strategy paves a facile way to achieve high performance NF membranes.

Chronic bisphenol exposure is a recognized disruptor of liver function, and although ferroptosis has been implicated, the underlying molecular mechanisms remain poorly defined. Here, integrative chemical proteomics and untargeted metabolomics were used to elucidate mechanisms of ferroptosis induced by bisphenol A (BPA) and bisphenol S (BPS) in hepatic cells. BPA elicited a pronounced ferroptotic phenotype, whereas BPS elicited a moderate phenotype in hepatocytes. Glutathione peroxidase 4 (GPX4) and pyruvate kinase M2 isoform (PKM2) were identified as critical targets, respectively. Validation through cellular thermal shift assay (CETSA), surface plasmon resonance (SPR), and molecular docking confirmed that BPA specifically binds to GPX4 (KD = 37.6 μM), while BPS exhibits moderate affinity for PKM2 (KD = 14.4 μM). Functional rescue experiments demonstrated that GPX4 overexpression effectively reversed BPA-induced ferroptosis and partially alleviated BPS-induced effects, whereas PKM2 overexpression specifically mitigated BPS-triggered cytotoxicity. Mechanistically, BPA inhibited GPX4 activity, impairing lipid peroxide detoxification and triggering ferroptosis; BPS suppressed PKM2, promoting glucose flux toward the methylglyoxal (MGO) pathway, depleting glutathione, and activating oxidative stress, thereby inducing ferroptosis indirectly. This study clarifies bisphenol-induced ferroptosis via target heterogeneity, providing mechanistic insights that may inform future safety evaluations.

Benefiting from the low cost and natural abundance of sulfur, as well as its excellent theoretical performance metrics - including a capacity of 1675 mAh g −1 and an energy density of 2600 Wh kg −1 - lithium-sulfur (Li-S) batteries have attracted considerable attention for next-generation energy storage. However, their practical deployment is severely hindered by the intrinsic shuttle effect of lithium polysulfides (LiPSs), which leads to the loss of active materials and poor cycling stability. In this work, we report a facile hydrothermal-calcination strategy to synthesize porous nanosheet-structured Fe-doped nickel oxide (Fe-NiO) as a functional separator modifier for Li-S batteries. The polar nature of NiO enables strong chemical interactions with LiPSs, effectively anchoring polysulfides on the cathode side and suppressing the shuttle effect. Furthermore, Fe doping significantly increases the density of surface active sites, thereby enhancing the adsorption and catalytic conversion of LiPSs into insoluble Li 2 S 2 /Li 2 S species, which promotes redox kinetics and mitigates capacity fading. When applied to Li-S cells, the Fe-NiO-modified separator markedly improves the electrochemical performance, delivering a high reversible capacity of 1150 mAh g −1 at 0.2C, an excellent rate capability of 505 mAh g −1 at 5C, and outstanding long-term stability with a minimal capacity decay of 0.091 % per cycle over 500 cycles at 1C. This study presents a simple and scalable strategy for separator engineering, providing a promising pathway toward high-performance Li-S batteries.

Superionic β -Ag 2 S demonstrates exceptional ionic conductivity and ductility, rendering highly promising for applications in electrochemical sensors, thermoelectric devices and solid-state electrolytes. However, it is still haunted by the limited thermodynamic stability, transitioning to the poorly conductive α -Ag 2 S phase upon cooling to room temperature (RT). Herein, a solid solution formed by partial isovalent substitution of sulfur with tellurium stabilizes the superionic phase via the substantial atomic-size mismatch between S and Te. Specifically, Ag 2 S 1-x Te x (0.2 ≤ x ≤ 0.8) maintain superionic phase at RT without observable phase transition upon cooling. This stabilized superionic phase originates from the substantial size mismatched between S and Te. Furthermore, the anion disorder caused by the local volume expansion introduced by large-radius Te reduces the activation energy the activation energy barrier and provides more vacancies for Ag + ion transportation. This work confirms the efficiency of crystal amorphization strategy for stabilizing high-temperature superionic phases at ambient conditions, enabling the development of superionic conductors.

Three ionic liquid (IL) monomers consisting of one, two, and four benzene rings were designed with 2-phenylimidazole and polymerized with α,α′-dichloro-p-xylene (DCX) and formaldehyde dimethyl acetal (FDA) to form a series of novel poly(ionic liquid)s (PILs). In this process, the designed ILs were employed as active ionic sites, and DCX and FDA were selected as cross-linkers. Self-condensation of the cross-linker provided a large specific surface area for the hypercross-linked organic framework, while co-condensation between the cross-linker and IL introduced active sites to the framework. The obtained porous hypercross-linked PILs not only promoted CO2 capture and the selective absorption of CO2/N2 but also showed good activity for the cycloaddition of epoxide with CO2. HP-[BZPhIm]Cl-DCX-1 with a large surface area (763 m2·g–1) showed a CO2 uptake capacity of 1.47 mmol·g–1 and offered a 98.9% yield of the CO2 cycloaddition product with epichlorohydrin at 80 °C for 24 h under 0.1 MPa CO2 pressure. The designed PILs provide an important reaction for CO2 utilization.

Solar vapor generation is a sustainable and cost-effective approach to addressing the issue of water shortage. However, the challenges of solar steam generation still exist for achieving a high evaporation efficiency combined with long-term stability in the wastewater containing heavy metal ions and wide degrees of acidity and alkalinity (pH = 1–14). Herein, polypyrrole (PPy) loading on the N,S-doped graphene oxide (N,S-GO) foam is used for high-efficiency solar evaporation of treating wastewater. With the advantages of excellent broadband solar absorption ( >97%), extremely low emissivity (0.70), and outstanding hydrophilicity, the N,S-GO/PPy foam achieves a high evaporation efficiency of 90.5% under 1 sun illumination. More notably, the N,S-GO/PPy foam has strong adsorption of heavy metal ions (Fe 3+ , Cu 2+ , and Cr 6+ ) for treating wastewater synchronously evaporates at higher efficiencies of 94.7–98.4%. Interestingly, the high-toxicity Cr 6+ can be reduced to low-toxicity Cr 3+ effectively by the synergistic effect of N,S-GO and PPy. In addition, the N,S-GO foam shows a better long-term resistance of acidity and alkalinity for 45 days. A new insight is offered into high-efficiency solar evaporation for treating wastewater and water purification.

Lithium–sulfur (Li–S) batteries are promising to enable high-energy-density storage systems; however, their commercialization is hampered by several technical challenges such as polysulfide shuttle and safety issues related to the lithium metal anode. Herein, we use anodized aluminum oxide (AAO) membranes as separators in Li–S batteries for the first time. AAO membranes are rigid and nonflammable, which is helpful for improving battery safety. The aligned and uniform channels within AAO membranes provide fast pathways for lithium ion transport, leading to low areal specific resistance due to the electroosmotic flow of lithium ions in nanoscaled channels. In addition, the AAO separator leads to low overpotential during lithium deposition/stripping in lithium symmetric cells. The Li–S cells with AAO separators show better cycling performance than those with Celgard ones, in particular, at high C rates. At the 2 C rate, the cell shows a battery performance of 480 cycles with a capacity degradation rate of 0.105%, which is much better than that when the Celgard separator is used. This work demonstrates that AAO membranes are promising separators with unique properties for improving the performance of Li–S batteries.

Summary As one of the most promising energy storage systems, the application of lithium sulfur battery is hindered by low ionic conductivity, poor thermal stability, and a serious shuttle effect of polysulfide species of commercial polyolefin separators. Herein, a kind of novel porous polyetherimide (PEI) based separator (IAPEI-4) with excellent heat resistance and electrochemical properties was prepared. Briefly, by grafting amino group (–NH 2 ) onto the surface of SiO 2 , highly dispersed amino-functionalized SiO 2 (A-SiO 2 ) were synthesized as fillers to blend PEI matrix. Based on physical characterizations of the representative IAPEI-4 separator, abundant micropores and mesopores exist in the separator, and A-SiO 2 nanoparticles are uniformly distributed in the PEI matrix. The ameliorated Li + transport channels and the uniform distribution of A-SiO 2 nanoparticles endow IAPEI-4 separator with higher ionic conductivity (1.60 mS cm −1 ) and Li + transfer number (0.63). Besides, the IAPEI-4 separator exhibits good electrochemical stability and excellent thermal stability (no shrinkage at 200°C). The Li-S cells with the IAPEI separator also show greatly enhanced electrochemical performances. After 100 cycles, its specific discharge capacity can reach 695.4 mAh g −1 at 0.2 C and its capacity retention rate is 84.8%. This simple and effective separator modification method can provide a general strategy to achieve high-performance Li-S batteries.

Aqueous Zn─S batteries are promising energy storage systems with high theoretical capacity and low cost. However, the direct conversion between S and ZnS at the cathode suffers extremely sluggish reaction kinetics, which further decay rapidly upon the increase of current density and active material loading. Facing these challenges, we herein present a bi-directional redox mediator strategy and identify a self-adjusted Cu-based candidate. It possesses two redox couples whose potentials are on either side of the thermodynamic redox potential of S/ZnS reaction while between its kinetic oxidation and reduction potentials. These alignments enable the bi-directional mediator to catalyze the charge and discharge processes using either redox couple, respectively. As a result, the sulfur cathode reaches a high capacity of 1629 mAh g −1 at 0.1 A g −1 . It also maintains 880 mAh g −1 after 500 cycles at 1 A g −1 , superior to rapid decay to 148 mAh g −1 after only 28 cycles with the mediator free cathode. Furthermore, with a high sulfur loading of 7.3 mg cm −2 and lean electrolyte of 7 µL mg S −1 , the Zn─S battery achieves a high areal capacity over 10 mAh cm −2 .
