Hydrogen (H2) energy is a clean, renewable energy carrier with a high energy density and zero carbon emissions. Photocatalytic water splitting offers a promising route to H2 production by utilizing abundant solar energy; yet, it is often limited by sluggish charge carrier kinetics and low quantum efficiency. Herein, we incorporate graphene quantum dots (GQDs) as cocatalysts into the S-scheme heterojunction inorganic semiconductor Bi2MoO6@Cu2O (BMO@Cu2O) to boost photocatalytic H2 evolution. Under simulated sunlight, the GQDs/BMO@Cu2O composite achieves an exceptional H2 production rate of 16.1 mmol·g–1·h–1 and an apparent quantum yield of 33.6% at 420 nm. The built-in electric field (IEF) between BMO and Cu2O promotes S-scheme charge transfer, enhancing carrier separation. GQDs function as electron acceptors and active sites, where their delocalized π-electron cloud in the sp2-hybridized carbon skeleton shortens charge migration paths and lowers the energy barrier for surface H2 evolution. In situ X-ray photoelectron spectroscopy, Kelvin probe force microscopy, and density functional theory calculations collectively confirm the IEF and S-scheme electron transfer. This work presents a strategic design of GQDs-mediated heterojunctions with efficient charge separation and strong redox capacity, advancing solar-driven H2 production technology.

Advancing toward “dual-carbon” goals and clean hydrogen production, developing visible-light photocatalysts with high activity and durability remains a challenge. Here, Mg-doping engineered CdS/NiCoAl-LDH heterojunctions are constructed and investigated to clarify how Mg incorporation co-modulates structure, band energetics, and hydrogen-evolution behavior. Multiscale characterizations combined with density functional theory (DFT) calculations show that appropriate Mg doping strengthens visible-light absorption, suppresses photogenerated electron-hole recombination, reduces interfacial charge transfer resistance, and optimizes band alignment, with the conduction band shifting to more negative potential and the valence band shifting upward, thereby strengthening the reducing power of photogenerated electrons and enhancing the thermodynamic driving force for HER. Under 4 h of visible-light irradiation, CdS/NiCoAlMg(10 %)-LDH achieves a hydrogen evolution rate of 5984.12 μmol·g⁻ 1 ·h⁻ 1 , 2.82 times that of the undoped sample, and retains over 95 % of its initial activity after four cycles, indicating good activity and cycling stability. DFT analysis reveals that Mg partially substitutes Ni, redistributes electronic states near the Fermi level, and optimizes hydrogen adsorption at Co active sites, thereby lowering reaction barriers for the hydrogen evolution reaction. Overall, Mg doping tunes band edges, optimizes active-site electronic structure, and accelerates interfacial charge transport in CdS/NiCoAl-LDH, leading to enhanced photocatalytic hydrogen evolution under visible light.

Achieving a simultaneous enhancement of heat resistance and solubility remains a longstanding challenge for high-performance polyarylethers. Here, we report a molecular-engineering strategy that integrates a rigid and non-coplanar dibenzofuran-bridged bisphthalazinone units into the polymer backbone to create a novel series of poly(aryl sulfone ketone)s (PFPSKs). The introduction of the dibenzofuran-bridged bisphthalazinone units simultaneously enhance backbone rigidity and disrupts dense chain packing, offering a balance between exceptional thermal stability and desirable solubility. The PFPSKs exhibit high glass-transition temperatures ( T g = 376–391 ℃), excellent thermal resistance ( T d5% above 509 ℃ in N 2 and air), and high storage-modulus retention up to 350 ℃ (57.4%). The polymers dissolve readily in 1,1,2,2-tetrachloroethane and N -methyl-2-pyrrolidone (NMP), enabling the preparation of mechanically robust films with tensile strengths of 93.4–96.1 MPa and moduli of 1.94–2.38 GPa. Concurrently, the PFPSK films exhibit commendable light transmittance (76–78% at 800 nm) and dielectric properties (2.97 to 3.26 at 1 MHz), alongside favourable solution recovery characteristics. Additionally, coatings fabricated by solution spraying display excellent hardness (4H), strong adhesion (5.40–7.20 MPa), good flexibility, and high impact resistance (55 cm), together with outstanding salt-spray durability and closed-loop recyclability. PFPSKs also demonstrate intrinsic flame retardancy, achieving UL-94 V-0 rating without additives. This work establishes a versatile molecular-design platform that overcomes classical trade-offs in polyarylethers and opens pathways toward multifunctional, flame-resistant, and recyclable high-temperature polymers.

A robust all-inorganic S-scheme Cu 3 SnS 4 (CTS4)/ α-Fe 2 O 3 composite nanotube array photoanode, demonstrating superior photoelectrochemical cathodic protection (PECCP) performance, was fabricated by in-situ growing α-Fe 2 O 3 on carbon steel through anodization, followed by anchoring CTS4 nanoparticles onto the vertically aligned nanotubes using a hydrothermal method. The construction of the CTS4/α-Fe 2 O 3 S-scheme heterojunction broaden visible light absorption capability and optimize charge carrier separation simultaneously, enabling significantly enhancing the prevention of Q235 carbon steel corrosion. Under visible light, the optimized composite on Q235 steel coupling led to a 480 mV OCP drop (vs. Ag/AgCl) and a photocurrent density of 32 µA/cm². A synergistic effect between the electron transport channels in nanotube arrays and the charge separation induced by the S-scheme mechanism underpins the substantial performance improvement. This work provides new insights into the design of highly efficient S-scheme photoanodes for stable and sustainable marine corrosion protection.

Rhabdomyolysis-induced acute kidney injury (RM-AKI) is a life-threatening clinical condition characterized by excessive myoglobin release, leading to kidney tubular obstruction, oxidative stress, and iron-mediated lipid peroxidation. However, current therapies fail to effectively suppress oxidative stress cascades and lack kidney targeting. Herein, we developed a kidney-targeted nanodrug delivery system with multimodal antioxidant functionality (DFO@SOC) for RM-AKI therapy. Using antioxidant capacity as the decisive screening criterion, Se/S co -doped onion-derived carbon dots (SOC) were identified as the optimal nanocarrier through systematic natural polyphenol precursor selection and heteroatom-doping optimization. SOC exhibited pronounced superoxide dismutase-like and catalase-like activities. The iron chelator deferoxamine (DFO) was subsequently loaded onto SOC, yielding uniformly sized, negatively charged DFO@SOC nanoparticles. In vitro studies demonstrated efficient cellular uptake, robust intracellular scavenging of reactive oxygen species (ROS) and iron ions, and negligible cytotoxicity. In an RM-AKI mouse model, DFO@SOC selectively accumulated in injured kidneys. Notably, Sound Touch Visco-elastography (STVi) and Quantitative Tissue Scattering Coefficient (QTSC) enabled noninvasive and real-time evaluation of therapeutic efficacy with kidney stiffness decreasing significantly from ~14 to 7 kPa. Combined biochemical and histopathological analyses, DFO@SOC treatment significantly reduced Scr from ~193.31 to ~93.82 μmol/L and blood urea nitrogen (BUN) from ~52.99 to ~30.68 mmol/L compared to the model group. In summary, the synergistic antioxidant and iron-chelation effects of DFO and SOC, establishing DFO@SOC as a promising nanotherapeutic strategy for RM-AKI.

Interfacial engineering in heterostructure photocatalysts is crucial for efficient charge migration, yet achieving rational and controllable interface design remains a major challenge. In this work, SnIn 4 S 8 nanosheets were in situ grown on the octahedral surface of MIL-101(Cr) to leverage the Lewis acid-base properties of Cr and S, thereby enabling the controlled construction of an ion-coordinated interface. The resulting MIL-101(Cr)@SnIn 4 S 8 heterojunction enabled efficient capture and conversion of CO 2 and H 2 O. Furthermore, the Lewis acid-base coordination induces interfacial electron density redistribution, generating a built-in electric field that drives the formation of an S-scheme heterojunction between MIL-101(Cr) and SnIn 4 S 8 , while simultaneously preserving high‑energy photogenerated electron-hole pairs. Consequently, MIL-101(Cr)@SnIn 4 S 8 exhibited superior CO 2 photoreduction performance with H 2 O in the gas-solid phase, delivering a CO evolution rate of 26.9 μmol·g −1 ·h −1 . This work provides a viable strategy for interfacial engineering and demonstrates the application potential of S-scheme heterojunctions in photocatalytic reactions.

Al/Bi-O acid-base pairs were built by spatially selective Al doping in BiOBr/Bi 2 O 3 heterojunction. • The NH 3 yield reached 801.3 μmol g −1 h −1 in pure water, exceeding transition metal doped systems. • Al 3+ polarization activates lattice oxygen as primary Lewis base sites. • In situ KPFM visualizes S scheme charge transfer and the amplified built in field from Al doping. • Oxygen vacancies supply π backdonation channels and enrich electron density of nearby lattice oxygen. Photocatalytic nitrogen fixation has long been constrained by the intrinsic inertness of the N N bond and the severe recombination of photoexcited electron-hole pairs. Here, we construct an aluminum-doped BiOBr/Bi 2 O 3 S-scheme heterojunction in which Al 3 + selectively replaces Bi 3+ sites in the BiOBr lattice, while the Bi 2 O 3 phase retains its inherent crystal structure almost entirely. This asymmetric doping configuration strengthens the internal electric field across the S-scheme interface. The strong polarizing ability of Al 3+ activates nearby lattice oxygen atoms into Lewis base sites and induces the formation of additional oxygen vacancies (Ov), while simultaneously extracting electron density from adjacent Bi centers via Al-O-Bi bridge bonds, thereby enhancing the Lewis acidity of Bi. The resulting Al/Bi-O Lewis acid-base pair activates N 2 through a synergistic push-pull mechanism, in conjunction with the charge modulation induced by the oxygen vacancies. In pure water and in the absence of any sacrificial agent, the optimally designed photocatalyst achieves an NH 3 production rate as high as 801.3 μmol g −1 h −1 under simulated sunlight, surpassing transition-metal-doped analogues. This work establishes a lattice-confined Lewis acid-base pair paradigm, opening a new avenue for designing high-efficiency nitrogen-fixing photocatalysts.

Solar-driven photocatalytic hydrogen evolution represents a promising strategy, yet constructing photocatalysts that simultaneously deliver high activity and efficient visible-light utilization remains challenging. In this work, an Fe-ion-doped metal–organic framework, MIL-68(Fe), was synthesized and employed as substrate template for in-situ growth of ZnIn₂S₄ nanosheets. Subsequent one-pot synthesis yielded hollow tubular MIL-68(Fe)/ZnIn₂S₄ composite uniformly coated with ZnIn₂S₄ nanosheets, effectively mitigating severe stacking inherent to pure ZnIn₂S₄. Characterization confirmed successful Fe-ion doping, which significantly enhanced visible-light absorption. The optimal composite achieved photocatalytic hydrogen evolution rate of 10.04 mmol·g −1 ·h −1 , representing 9.84-fold enhancement over pristine ZnIn₂S₄. Density functional theory calculations revealed that interfacial Fe O and in O bonds facilitate built-in electric field formation within [ZnS₄] layers, confirming successful S-scheme heterojunction construction. This unique structure preserves photogenerated charge carriers with stronger redox potentials, thereby substantially boosting overall photocatalytic activity. This study offers novel approach for photocatalyst modification and demonstrates synergistic combination of ion doping with S-scheme heterojunction engineering as highly promising research direction

Although MOF-derived materials are promising candidates for microwave absorption, precisely regulating their electromagnetic behavior through microstructure engineering remains a considerable challenge. Herein, a synergistic strategy integrating hollow hierarchical architectures with heteroatom doping is implemented to overcome this limitation. Hollow NiCo-BTC microspheres were employed as the precursor and subjected to calcination in the presence of melamine, which induced the in-situ growth of carbon nanotubes on the surface to form hierarchical hollow NiCo@NCNTs architectures. Subsequent sulfur doping via chemical vapor deposition (CVD) yielded NiCo@NCNTs/S composites with tunable sulfur contents. The hollow architecture significantly enhanced impedance matching and facilitated multiple scattering of microwave within the structure. The hierarchical nanostructures constructed abundant heterogeneous interfaces, effectively augmenting interfacial polarization. Crucially, the coexistence of surface sulfoxides, thiophenic sulfur, and structural defects synergistically modulates the electronic structure. This multi-faceted regulation elevates free electron density while introducing additional dipole and defect-induced polarization centers, thereby establishing an optimal equilibrium between conduction loss and polarization loss. Consequently, the optimized NiCo@NCNTs/S-5 composite exhibited exceptional microwave absorption performance, achieving a maximum reflection loss of −39.73 dB and an effective absorption bandwidth of 4.56 GHz with a thin thickness. This work elucidates a rational design paradigm for MOF-derived absorbers through hollow-hierarchical morphology control and heteroatom doping regulation, offering a viable pathway toward high-performance microwave absorption for practical applications. The integration of hollow hierarchical structure construction and sulfur doping enables precise modulation of the electromagnetic properties of the material. The hollow architecture optimizes impedance matching and triggers multiple microwave scattering, while the hierarchical nanostructures afford abundant heterogeneous interfaces to strengthen interfacial polarization. Sulfoxide groups, thiophene-type sulfur species and structural defects coexist on the material surface, synergistically tuning the electronic structure. This multidimensional regulation strategy elevates the free electron concentration and simultaneously introduces dipole and defect polarization centers, balancing conductive loss and polarization loss. The optimized NiCo@NCNTs/S-5 absorber achieves a minimum reflection loss (RL max ) of −39.73 dB and an effective absorption bandwidth (EAB) of 4.56 GHz at a thickness of 2 mm.

To address the prevalent problems of rapid photogenerated carrier recombination and insufficient redox capacity in photocatalytic hydrogen evolution, this work constructs a ZnWO 4 /Mn 0.2 Cd 0.8 S (ZWO/MCS) heterojunction photocatalyst featuring an S-scheme band structure. The addition of ZnWO₄ (ZWO) significantly boosts the photocatalytic activity of Mn 0.2 Cd 0.8 S (MCS). Under irradiation with simulated visible light, the 20ZWO/MCS composite exhibited the highest hydrogen production rate (30.22 mmol·g −1 ·h −1 ), 44.44 times that of pure ZWO and 4.51 times that of pure MCS, respectively. It also demonstrates excellent catalytic stability during continuous cycling tests. Through a systematic investigation of its structure, optoelectronic properties, and photocatalytic hydrogen evolution performance, combined with density functional theory (DFT) theoretical calculations, it was confirmed that a tight heterointerface forms between ZWO and MCS, establishing an S-scheme interfacial charge transfer route driven by the internal electrical field (IEF). Through the pathway, the photogenerated charges are efficiently separated spatially, with electrons enriched in the conduction band of MCS for proton reduction for hydrogen production, while holes gather within the valence band of ZWO. The study deepens the understanding of the behavior of charge carriers in S-scheme heterojunctions regarding their separation and migration, providing theoretical foundations and material design strategies for developing high-performance photocatalytic systems. Combined with in-situ experimental characterization and DFT theoretical calculations, it has been confirmed that the built-in electric field (IEF) formed by the difference in work function drives the migration of photo generated electrons from ZWO to MCS, following an S-shaped charge transfer path, achieving efficient spatial separation of charge carriers.

A bottom-gate-modulated carbon-based FET is developed for room-temperature H 2 S detection. • Complete recovery is achieved by purely electrical activation without external assistance. • The sensor shows favorable selectivity and stability for miniaturized, integrated sensing applications. Increasing attention has been paid to the detection of hazardous gases under room-temperature operating conditions. To address this, this work proposes a novel strategy based on a bottom-gate modulated carbon-based field-effect transistor (FET) for efficient room-temperature H₂S sensing. The FET-type gas sensor was constructed by integrating ZnWO₄/WO₃ composites with the carbon nanotube channel. It was found that applying a −1.5 V bottom-gate bias effectively modulates the surface electronic states of the sensing material, leading to significantly enhanced device performance: a response time of 28 s and a recovery time of 92 s toward 10 ppm H₂S at room temperature, enabling both rapid response and complete recovery. Furthermore, the sensor exhibits a favorable concentration-dependent response within 1–10 ppm, while maintaining high selectivity, consistent reproducibility, and durable long-term stability (maximum response fluctuation <7.1% over 15 days). The performance enhancement is primarily attributed to the gate-bias-facilitated regeneration of adsorbed oxygen species on the material surface. This work not only provides an innovative approach for room-temperature, low-power H₂S detection but also offers a new pathway toward the development of miniaturized and integratable gas sensors.

The electrocatalytic CO 2 reduction reaction (ECR) represents a promising strategy for converting CO 2 into value-added chemicals while mitigating greenhouse gas emissions. However, developing efficient and stable electrocatalysts remains challenging. In this study, we synthesized a Ni-based single-atom catalyst (Ni/NSP-C) via pyrolysis of a PZS/Ni-ZIF-8 precursor derived from ZIF-8. The resulting catalyst exhibits a hollow polyhedral structure with high surface area and porosity. Crucially, heteroatoms S and P were successfully incorporated into the primary coordination shell of Ni active sites, forming Ni-S and Ni-P bonds that modulate the electronic structure. Electrochemical tests revealed that Ni/NSP-C exhibits efficient ECR performance: a high current density of 402.3 mA cm -2 at -1.5 V vs. RHE, and CO Faradaic efficiency above 94 % over a wide potential window (-0.4 to -1.2 V), reaching 99.61 % at -0.8 V. The catalyst also demonstrated excellent stability over 24 h. Density functional theory (DFT) calculations further revealed that the S and P co-doping lowers the energy barrier for *COOH formation and suppresses the hydrogen evolution reaction, thereby enhancing ECR selectivity and efficiency. This work provides a universal coordination engineering strategy for optimizing the performance of single-atom catalysts in various electrocatalytic applications.
