Achieving efficient and stable solar-driven photocatalytic water splitting for hydrogen production requires simultaneously overcoming the issues of insufficient charge separation at the microscopic scale and difficult catalyst recovery at the macroscopic scale. In this study, an S-Scheme ZnCdS/CoS2 heterojunction catalyst was integrated into a PVDF/PVP/TiO2 electrospun fiber membrane via electrospinning technology, constructing a catalytic material that combines microscopic heterojunctions with a macroscopic membrane structure to realize synergistic enhancement between the microscopic heterojunction and the macroscopic assembly. At the microscopic level, the S-scheme heterojunction promotes the separation of photogenerated charge carriers through an internal electric field, thereby increasing the hydrogen production rate to 36.47 μmol/mg, which is 5 times higher than that of pure ZnCdS catalyst. At the macroscopic level, the PVDF/PVP/TiO2 electrospun fiber membrane provides a stable support for the ZnCdS/CoS2 S-scheme heterojunction, increasing active sites while enabling easy recovery. The hydrogen production efficiency of this fiber membrane is 2.3 times that of the powdered ZnCdS/CoS2 heterojunction, with an activity retention rate of 90.7% after repeated use. This study’s strategy of combining heterojunctions with electrospinning offers a feasible approach to simultaneously enhance the hydrogen production efficiency, stability, and recyclability of photocatalytic systems.

Phase interface engineering plays an essential role in the design and development of effective electromagnetic wave (EMW) absorption materials and energy storage devices. Nevertheless, the development of multifunctional materials that can simultaneously tackle these challenges remains a significant difficulty. In this study, we developed multifunctional defect-rich 1T/2H-WX2/RGO (X = S, Se) nanosheets utilizing a simple solvothermal and freeze-drying technique. The synthesized 1T/2H-WX2/RGO nanosheets exhibited superior EMW absorption and electrochemical characteristics. The effective absorption bandwidth (EAB) reached 7.68 GHz at a thickness of 3.10 mm. This excellent performance can be attributed to various loss mechanisms, including conductive loss, defect-induced dipole polarization loss and interface polarization loss. Moreover, the 1T/2H-WS2/RGO-15 nanosheets attained a high specific capacitance of 390.44 F g−1 at a current density of 1 A g−1. In contrast, the 1T/2H-WSe2/RGO-4 nanosheets demonstrated impressive cycling stability of 71.81% after 5000 cycles, which can be attributed to the active sites provided by its rich heterogeneous interface. The energy density of the 1T/2H-WS2/RGO-15 nanosheets was measured to be 4.27 Wh kg−1 at a power density of 400 W kg−1. This research offers valuable insights into the development of multifunctional materials that can serve as EMW absorbers and supercapacitor electrodes.

The coexistence of cationic and anionic dyes in wastewater necessitates the development of amphoteric adsorbents. Herein, amphoteric hydrogel microspheres SA-S@PDA-H was successfully fabricated for their simultaneous removal. The microspheres were synthesized by crosslinking sodium alginate (SA) with Ca²⁺, followed by coating with polydopamine (PDA) and stearyl trimethyl ammonium chloride (STAC). The microspheres prepared through acid treatment to replace STAC was labeled SA-S@PDA-H, endowing the microspheres with enhanced adsorption capacity. FT-IR, SEM, zeta potential was utilized to characterize the structure and morphology of SA-S@PDA-H. The adsorption behavior and mechanism of SA-S@PDA-H for cationic and anionic dyes was investigated in depth. The results show SA-S@PDA-H exhibit 127.3 % of swelling ratio. The adsorption of SA-S@PDA-H for MB and MO reaches equilibrium at about 300 min followed by PSO model. The adsorption process of SA-S@PDA-H for MB and MO followed Temkin and Dubinin-Radushkevich model, respectively, and the maximum adsorption capacity displayed 869.1 mg/g at 45°C and 730.9 mg/g at 15°C, for MB and MO, respectively. MB adsorption increased with higher temperature and pH, while MO adsorption increased with lower temperature and pH. Adsorption of both dyes decreased at high ionic strength, and Cu 2 + and Fe 3+ had a significant inhibitory for MB than K + , while the inhibitory effects of SO 4 2- or CO 3 2- is more obvious for MO than Cl - . SA-S@PDA-H exhibited excellent adsorption performance for mixed cationic and anionic dyes through synergistic effects including electrostatic interactions, hydrogen bonds, π-π stacking and micropore filling. The microspheres maintained over 80 % removal efficiency after five consecutive adsorption-desorption cycles.

More efficient N 2 activation and carrier dynamics are needed for effective solar-driven ammonia synthesis. Herein, a heterojunction photocatalyst (Co-ZnO/MIL-125(SH) 2 ) was constructed by using MIL-125(Ti) with sulfhydryl functionalization and Co-doped ZnO for photocatalytic nitrogen fixation. A series of characterization reveal that the formation of S-scheme charge transfer greatly enhances interfacial charge separation for more available carriers. The presence of Ti 3 + sites in MIL-125(SH) 2 also facilitates the adsorption and activation of N 2 , effectively leveraging the photogenerated electrons for N 2 conversion. Moreover, the introduction of Co-ZnO increases the hydrophilicity of the catalytic surface. This allows more water molecules to be oxidized by photogenerated holes to release H + for the N 2 hydrogeneration process. As a result, a high photocatalytic ammonia production rate of 50.8 μmol•g −1 •h −1 is achieved under visible light irradiation. This study presents an insight into engineering S-scheme heterojunction composite by coupling molecular coordinate activation and improved protons supply for efficient photocatalytic nitrogen fixation.

Basic Fuchsin (BF), a recalcitrant organic dye, poses severe risks to aquatic ecosystems and human health, necessitating the development of efficient and stable environmental remediation technologies. Herein, a novel direct S-scheme heterojunction photocatalyst (MG-CQDs/TiO 2 ) was prepared by impregnating and calcining TiO 2 with mango peel-derived carbon quantum dots (MG-CQDs). The successful construction of the S-scheme charge-transfer heterostructure was systematically elucidated through band structure analysis and electron paramagnetic resonance (EPR) spectroscopy. Under ultraviolet–visible (UV–Vis) light irradiation, the MG-CQDs/TiO 2 composite exhibited exceptional photocatalytic performance, achieving a remarkable BF degradation efficiency of 96.5% within 180 min. Notably, its reaction rate constant was 2.1 times higher than that of pristine TiO 2 . Mechanistically, the synergistic interaction between MG-CQDs and TiO 2 significantly promotes the spatial separation of photogenerated carriers. Radical trapping experiments further confirmed that superoxide (·O 2 − ) and hydroxyl (·OH) radicals serve as the primary reactive oxygen species driving the oxidation process. Crucially, density functional theory (DFT) calculations combined with Fukui index analyses provided molecular-level insights into the degradation pathway, identifying the nitrogen atoms and the central carbon of the BF molecule as the preferential sites for radical attack. Furthermore, the composite demonstrated outstanding photostability, maintaining highly efficient degradation over multiple consecutive cycles. Supported by both macroscopic experimental evidence and microscopic theoretical calculations, this study presents a highly efficient, cost-effective, and green paradigm for the advanced treatment of industrial dye wastewater.

Synaptic loss and aberrant protein S-nitrosylation (SNO) are strongly linked to cognitive decline in both patients and animal models of Alzheimer’s disease (AD). Our recent work in an AD mouse model has shed light on the role of oligosaccharides extracted from black ginseng (OSBG) in ameliorating cognitive impairment. However, the precise molecular mechanisms responsible for therapeutic efficacy of OSBG in AD are not well understood. In the present study, we employed an innovative SNOTRAP-based proteomic approach to quantify SNO proteins in the brain of APP/PS1 mice following OSBG intervention. The results revealed that differentially expressed SNO proteins, such as SNO-NOX1 and SNO- NOX5, confirmed by Western blot (WB), are significantly enriched in pathways related to oxidative stress, such as “Oxidative_stress activation of NADPH oxidase” and “Synaptic target recognition”. OSBG treatment significantly alleviated oxidative stress via inhibition of NADPH oxidase activity in APP/PS1 mouse and PC12 cells by WB immunofluorescence (IF) assays. More importantly, upregulation of PSD-95 and SYN1 was detected in the hippocampal tissue of APP/PS1 mice after OSBG intervention, which was further validated by the corresponding mRNA expression levels. Consistently, histopathological analysis revealed the restoration of hippocampal cellular structure. Overall, our findings highlight the synapse-protective effect of OSBG in an AD model through regulating protein SNO levels and inhibiting NADPH oxidase activity, revealing a novel mechanism by which OSBG alleviated oxidative stress injury.

The development of economical, efficient, and durable non-precious metal electrocatalysts for the hydrogen evolution reaction (HER) is crucial for the scalable production of green hydrogen via water electrolysis. This work reports a NiN x -derived P/S-modulated oxygen-containing reconstructed Ni-based microflower heterostructure grown in situ on nickel foam (NF), denoted as NiN x /NF-P,S. This unique three-dimensional porous microflower architecture provides a large accessible surface area and abundant catalytic interfaces, while the strong integration with the NF substrate ensures excellent structural stability during prolonged HER operation. The incorporation of P and S promotes the construction of heterogeneous interfaces and regulates the local electronic structure, while surface reconstruction under alkaline HER conditions introduces oxygen-containing Ni species, resulting in reconstructed catalytic interfaces favorable for HER. Consequently, the obtained NiN x /NF-P,S catalyst exhibits outstanding HER activity in alkaline media, requiring low overpotentials of only 17 and 70 mV to achieve current densities of 10 and 100 mA cm −2 , respectively. Furthermore, the catalyst maintains excellent long-term durability during continuous operation for 150 h. This work provides a promising strategy for constructing dynamically evolved non-precious metal heterostructured electrocatalysts.

The reaction between hexavalent chromium (Cr(VI)) and sulfite (S(IV)) holds promise for water decontamination but intrinsically favors a non-radical pathway, leading to toxic Cr(V) accumulation and inefficient radical yields. Herein, we constructed a heterogeneous carbon/Cr(VI)/S(IV) advanced oxidation system using carboxyl-rich carbon materials (CP-T and MWCNTs-COOH) to steer the reaction toward a radical-dominated pathway. Combined experimental and theoretical analyses unravel a surface-mediated ligand-exchange activation mechanism. Surface carboxyl groups function as specific anchoring sites, undergoing ligand exchange with Cr(VI) species to form a reactive Carbon-COO-Cr(VI) intermediate. Concurrently, the highly conductive carbon framework serves as an efficient electron conduit, facilitating rapid interfacial electron transfer from S(IV) to the anchored Cr centers. A dual-descriptor kinetic model was established, quantitatively demonstrating that the catalytic turnover is governed by a symmetric co-limitation regime; the intrinsic catalytic activity of the carboxyl sites is non-linearly amplified by the enhanced electron transport capability of the carbon network. This synergistic interplay simultaneously achieves complete Cr(VI)-to-Cr(III) detoxification and efficient sulfate radical (SO 4 •− ) generation. Furthermore, density functional theory (DFT) calculations elucidated the SO 4 •− -initiated degradation pathways for diclofenac (DCF). Operating efficiently in authentic water matrices under near-neutral conditions, this work provides a scalable and sustainable strategy for the synergistic remediation of complex metal-organic co-contamination.

Background The development of efficient and durable oxygen reduction reaction (ORR) catalysts plays a vital role in promoting the development of metal-air batteries (MABs). Methods Herein, a Co single-atom catalyst ( f -Co@SNC) supported on a flower-like S, N-codoped porous carbon substrate was prepared using a polydopamine-coated dual-linker zeolitic tetrazolate framework (ZTF) as a precursor. The polydopamine coating and 2-methylimidazole linker are used as structural stabilizers and provide nitrogen and carbon sources, while the thermally unstable and high-energy linker (5-aminotetrazole) and in-situ embedded thiourea guest serve as sacrificial templates to create abundant of S, N-codoped sites and well-developed porous structures. Significant Findings Benefiting from the high-density atomically dispersed single Co sites and structure advantages, the optimized f -Co@SNC catalyst exhibits excellent ORR catalytic performance with half-wave potential of 0.871 V and excellent catalytic stability over 10 h, even surpassing commercial Pt/C catalyst. Impressively, rechargeable zinc-air battery (ZAB) using f -Co@SNC as the air cathode catalyst exhibit a desired peak power density of 118.5 mW cm −2 , energy density of 794.6mAh g Zn −1 and an excellent charge-discharge cycle stability over 145 h. This work presents a facile method for preparing SACs for efficient ORR, which will provide meaningful guidance for promoting the development of next-generation clean energy conversion devices.

Lithium–sulfur (Li–S) batteries face low sulfur utilization and limited rate capability. Although electrolyte engineering is a key strategy for improving the conversion kinetics of lithium polysulfides (LiPS), achieving a balance between high energy density and high power density remains challenging. This study combines an ultra-low concentration electrolyte with a dual-functional hybrid organic selenium/organic tellurium additive (DPDSe/DPDTe). The system exhibits higher ionic conductivity and enhanced LiPS conversion kinetics. This is attributed to the high solubility of LiPS at low concentrations, which enhances the accessibility of active materials. By adjusting the mixing ratio of DPDSe/DPDTe, the formed DPDSe-Te exhibits unique solvation structure regulation and synergistic catalytic effects. This Li–S battery delivers an initial specific capacity of 1103 mAh g −1 (65.9% sulfur utilization) at 0.5 C and retains 89.3% of its capacity after 100 cycles. Even at 2 C, a capacity of 783 mAh g −1 is achieved. The pouch cell exhibits a high energy density of 340 Wh kg −1 at 0.5 C with stable cycling. This low-concentration, dual-functional additive strategy synergistically addresses LiPS solubility limitations and kinetic bottlenecks, offering an effective route toward Li–S batteries with both high energy density and high-power density.

Although scalable artificial photosynthesis for H 2 O 2 production is a promising technique, it is not yet widely adopted as an industrially viable process. Herein, a 2D n–n heterojunction photocatalyst has been fabricated by integrating hydroxyethyl cellulose (HEC)-modified g-C 3 N 4 with BiOBr. The heterojunction is denoted as CN- x /BOB- y , where x and y represent the mass ratios of HEC/g-C 3 N 4 and g-C 3 N 4 /BiOBr, respectively. Under simulated visible light irradiation, CN-0.4/BOB-0.5 achieves a remarkable H 2 O 2 production rate of 5897 μM g −1 h −1 , outperforming BiOBr and HEC/g-C 3 N 4 by factors of 2.04 and 2.38, respectively. It also records an apparent quantum yield (AQY) and mass-normalized AQY of 0.167% and 8.34E-02 molecules·photon −1 ·g −1 , respectively. The synergy between HEC modification and heterojunction construction underpins the superior performance, driving efficient charge carrier separation alongside a marked increase in specific surface area. Energy band alignment analysis and scavenger trapping experiments collectively reveal that charge carriers in CN-0.4/BOB-0.5 follow an S-scheme charge transfer pathway, enabling enhanced redox capability and efficient charge separation across the built-in electric field within a well-engineered heterojunction. This work presents a novel strategy for constructing a highly efficient photocatalytic system for H 2 O 2 generation under visible light irradiation.
