Photocatalytic NO oxidation to nitrate (NO 3 − ) is a promising technology for air pollution control. However, these strategies are hindered by slow kinetics as well as unwanted production of toxic NO 2 , which result from the inefficiency in separating charges and poor activation of the reactant molecules. Here, we report on a novel 2D/2D S-scheme heterojunction constructed by coupling CoAl-layered double hydroxide (CoAl-LDH) nanosheets with BiOBr nanoplates. This particular structure enables a S-scheme charge transfer channel that can improve the separation efficiency of photoinduced charge carrier while keeping strong redox ability to generate high-reactive oxygen species (ROS, including hydroxyl radical and superoxide radicals). Furthermore, in situ DRIFTS spectra showed that Co 3+ sites within the LDH framework are key active centers, significantly enhancing NO adsorption and activation. Consequently, the obtained CoAl-LDH/BiOBr composite exhibited excellent NO removal activity, to reach a conversion rate of 97.3% with negligible NO 2 formation (selectivity <3%) under visible light, and maintained excellent stability for 8 h. This study proposes a synergistic strategy of interfacial charge control coupled with surface catalytic site design, providing new perspectives in design of high-performance catalysts for future applications in environmental protection via photo-catalytic processes.

The growing demand for efficient separation technologies has spurred research into advanced materials. This study fabricates polyethersulfone (PES)/bisphenol S copoly (phthalazinone ether sulfone) (PPESS) hollow fiber membranes via solution blending to overcome performance-cost trade-offs in traditional single-material membranes. The compatibility of the two components was confirmed by DSC. The effects of different component contents in the formula on the thermodynamic stability, phase separation kinetics of the casting liquid and final membrane morphology were systematically investigated. Increasing the PPESS ratio, polymer concentration, or polyvinylpyrrolidone (PVP) additive content reduced the thermodynamic stability of the system and delayed phase separation to varying extents. This consequently led to a decrease in membrane pore size and increased the bovine serum albumin (BSA) rejection rate to above 95%. Considering permeability-selectivity trade-off, under a suitable spinning process, the blended membrane prepared with a PES/PPESS ratio of 8:2, a polymer content of 18 wt%, and a PVP content of 4 wt% exhibited the best overall performance, achieving a pure water flux of 109.5 L m −2 h −1 and a BSA rejection rate of 91.9%.

Quasi-solid-state
sodium–sulfur (Na–S)
batteries
are widely regarded as promising candidates for next-generation energy
storage due to their higher energy density and enhanced safety over
traditional liquid-electrolyte counterparts. However, electrolyte
solidification restricts ion transport within the sulfur cathode,
leading to poor sulfur utilization and exacerbating sluggish sodium
polysulfide (NaPS) conversion kinetics. Current cathode designs mitigate
this challenge by introducing a high proportion of conductive additives
to expand the sulfur–carbon-electrolyte triple-phase interfaces
(TPIs), which inevitably sacrifices the practical energy density of
the battery. This challenge becomes more severe under practical conditions
of high sulfur contents (50 wt %), where both ionic and electronic
pathways are simultaneously obstructed. Here, we develop a presodiated
TiO 2 (Na x TiO 2 ) electrocatalyst
possessing ion-electron dual-conductive characteristics via an electrochemical
ion-intercalation approach. The introduction of Na x TiO 2 extends the active surface beyond conventional
TPIs, enabling rapid catalytic conversion of NaPSs directly at the
sulfur-Na x TiO 2 dual-phase interfaces
(DPIs). Mechanistic studies show that Na intercalation modulates the
local Ti–O coordination environment and the Ti 3d-O 2p electronic
structure, which significantly improves the electronic conductivity
and interfacial Na + transfer kinetics of TiO 2 while reducing the energy barrier for the rate-determining Na 2 S 2 -to-Na 2 S step in NaPS conversion.
Consequently, an ultrahigh sulfur utilization exceeding 80% is achieved
in a high-sulfur-content cathode (70 wt %), delivering a high initial
specific capacity of 1391.2 mAh g –1 alongside robust
cyclability over 500 cycles. The assembled practical pouch cell achieves
an impressive energy density of 372 Wh kg –1 . This
work offers valuable insights into developing high-energy-density
solid-state Na–S batteries for practical applications.

N, S co-doped carbon coated 3D porous Mn 0.5 Ti 2 (PO 4 ) 3 was fabricated via fulvic acid pyrolysis. • The carbon layer synergistically enhances electronic conductivity and Li + diffusion kinetics. • The designed composite anode revealed outstanding rate capability. NASICON-structured Mn 0.5 Ti 2 (PO 4 ) 3 (MTP) has emerged as a competitive anode candidate for lithium-ion batteries (LIBs), benefiting from its abundant lattice vacancies, robust structural integrity, and suitable operating voltage. Nevertheless, the practical scalability is constrained by intrinsically low electronic conductivity. Herein, fulvic acid (FA) is employed as a carbon precursor to composite with MTP via high-temperature carbonization, aiming to optimize the electrochemical performance of MTP. Electrochemical tests reveal that the composite with FA/MTP weight ratio of 0.30 carbonized at 800℃ achieves enhanced cycling stability and rate capability, delivering lithiation capacities of 391.4 and 198.9 mAh g −1 at 0.1 and 1.6 A g −1 , respectively. The superior performance is attributed to the formation of uniform N, S co-doped carbon coating layer derived from in-situ carbonization of FA. N, S co-doping not only facilitates rapid electron transport and buffers volume changes during repeated lithiation/delithiation but also introduces additional active sites for lithium storage. Simultaneously, the incorporation of a co-doped carbon layer on MTP improves the binding affinity with MTP, thereby conferring outstanding structural durability and electrical conductivity of the composite. This work provides a simple and effective strategy for utilizing natural biomass derivatives to improve the electrochemical performance of polyanionic compounds for advanced LIB anodes.

Reducing soluble U(VI) to insoluble U(IV) is an efficient uranium extraction strategy. However, the two axial oxygen atoms in uranyl (UO 2 2 + ) create a kinetic barrier to electron transfer, hindering U(VI) reduction. Here, we present an innovative strategy that leverages the hydrogen evolution reaction (HER) to generate a localized alkaline microenvironment at the catalyst surface; OH⁻ accumulation rapidly precipitates UO 2 2 ⁺ as insoluble UO 2 (OH) 2 , enabling efficient uranium extraction from water. In this process, the S-rich hollow MoS 2+x with high HER activity, which was derived from the Mo-MOF grown on carbon felt (CF), was used as the cathode (MoS 2+x /CF) in a photovoltaic-driven electrocatalytic system. The anode consists of a TiO 2 nanorod array on FTO glass, coupled with a rear-mounted silicon solar cell. Due to the localized alkaline microenvironment formed by the HER on the MoS 2+x /CF cathode surface, this electrocatalytic system achieves 99.8% uranium removal from uranium-containing wastewater within 30 min of illumination. Density functional theory (DFT) calculations and experimental results confirm that unsaturated edge S atoms in MoS 2+x significantly enhance HER activity. Additionally, the electron transfer between uranium and edge S enhances uranium adsorption and promotes its interfacial reaction with OH*. This work opens new perspectives for uranium extraction from aqueous solutions.

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.

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.

Electrocatalytic oxidation of 5-hydroxymethylfurfural to prepare high-value-added chemicals is an effective solution for a sustainable alternative to fossil fuels. We report a novel one-step hydrothermal sulfurization strategy to construct hierarchical FeNi-S@NF nanoflower architectures comprising interconnected 2D nanosheets. This catalyst design synergistically integrates high conductivity (i.e., nickel foam (NF) substrate), abundant active sites (i.e., 2D nanosheet), and optimized electronic structure (i.e., sulfur doping), achieving exceptional electrocatalytic 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) conversion. By optimizing the classical two-step hydrothermal sulfidation approach through precise control of metal ratios and sulfidation duration, we significantly enhanced the catalytic performance for the HMF oxidation reaction (HMFOR). Sulfur doping was found to substantially improve the catalyst’s adsorption capability for HMFOR intermediates, thereby enhancing both activity and selectivity toward FDCA production. The optimized FeNi-S@NF nanoflower catalyst demonstrated superior electrocatalytic performance in 1 M KOH + 50 mM HMF, achieving 98.41% conversion rate, 92.08% FDCA yield, and 89.19% Faradaic efficiency at an applied potential of 1.45 V vs a reversible hydrogen electrode (RHE), surpassing most reported transition metal-based electrocatalysts. This research work provides a new strategy for the rapid and low-cost synthesis of two-dimensional sulfide nanoelectrocatalysts for the efficient electrooxidation process of biomass derivatives.

Increased safe and environmental awareness in production processes necessitates an ever-growing demand for efficient detection of ethanol/n-butanol/diesel fuel blends (clean energy) in rapid, real time. However, the forces between multiplexed organic molecules in complex environments induce a decrease in the flash point, thus requiring sensors with high selectivity and low-temperature detection capabilities. In this study, an In2O3/WO3 multilevel heterojunction is assembled by utilizing the electrostatic interaction between the hydroxyl group of In(OH)3 and WS2. The material achieves dual detection of ethanol and n-butanol under the excitation of light and temperature fields. It also possesses fast response/recovery times, excellent selectivity, and good long-term stability. The WO3 has a defect-rich (002) exposed surface in the In2O3/WO3 heterojunction, and the special electronic structure of the heterojunction induces carrier migration at the S-scheme heterointerface under photothermal activation, which promotes the generation of more reactive oxygen species (O2–, O–) from the sensing material. The special chemical reaction of the sensor between oxygen anions and the target gas at room temperature (RT) and 120 °C is the basis for the realization of dual-selective detection of ethanol and n-butanol. The sensing mechanism of the WO3/In2O3 heterojunction for ethanol/n-butanol has been systematically investigated based on energy band structure analysis and in situ Raman spectroscopic characterization. This work focuses on the potential of metal oxide-based S-scheme heterojunctions for high-performance gas sensor applications.

Lithium-ion batteries (LIBs) attract widespread attention as promising energy storage devices owing to their superior energy density, excellent cycle life, and absence of memory effect. However, they still encounter challenges in high-rate performance and structural stability, necessitating further optimization. This study focuses on a composite anode material constructed from black phosphorus (BP), tungsten disulfide (WS 2 ), and ultra-high-purity whisker carbon nanotubes (UWCNTs) (BP-WS 2 -UWCNTs). The research investigates the regulatory effects of phosphorus–carbon (P–C) and phosphorus–sulfur (P–S) bonds at the material interface on electrochemical performance. Characterization indicates the establishment of P–C and P–S bonds at the composite interface, which enhance structural integrity and improve electron/ion transport capabilities. Electrochemical performance evaluations validate the combined effect of these interfacial bonds: at 2.0 A g −1 , the BP-WS 2 -UWCNTs anode delivers 605.8 mAh g −1 for 2000 cycles, and retains 252.2 mAh g −1 after 3000 cycles even at 15.0 A g −1 , exhibiting remarkable rate performance and prolonged cycling durability. In practical applications of LIBs, the composite anode maintains robust structural integrity and outstanding electrochemical performance. This work highlights that the combined effect of interfacial P–C and P–S chemical linkages effectively facilitates lithium-ion diffusion and stabilizes the electrode structure, offering valuable insights and viable strategies for advancing high-capacity anode design in LIBs.

Tin selenide (SnSe), as a direct bandgap (1.1–1.3 eV) photovoltaic absorber material, has a theoretical power conversion efficiency comparable to commercial thin-film solar technologies. However, the efficiency of experimentally fabricated SnSe solar cells is significantly lower than the theoretical value, mainly constrained by two major bottlenecks: (1) the bulk defects leading to carrier recombination and (2) the bandgap mismatch at the interface. Additionally, the environmental toxicity of the CdS and its parasitic absorption of short-wavelength light also limit the sustainable development. This study proposes and systematically investigates the all-inorganic structure of FTO/Zn(O,S)/SnSe/Carbon. Replacing traditional CdS with Zn(O,S) can achieve tunable bandgaps and eliminate Cd toxicity. Through SCAPS-1D simulation, the thickness and carrier concentration of each functional layer are optimized, and the influences of bulk defect density, interface defect density, and resistance on device performance are analyzed. Meanwhile, the S content in Zn(O,S) is adjusted, and the sulfur enrichment (S content of 70%) induces the best conduction band offset (ΔEc = 0.05 eV). The resulting optimal device exhibits an efficiency of 22.46%, Voc = 0.90 V, Jsc = 30.06 mA/cm2, and FF = 83.39%. This work establishes a universal paradigm combining nontoxic material selection (Zn(O,S)/carbon), interface thermodynamic control, and defect passivation strategies, paving the way for the commercialization of sustainable thin-film solar cells.
