The practical implementation of lithium–sulfur (Li–S) batteries is still impeded by two fundamental challenges: the low conductivity of lithium sulfide species (Li2S2/Li2S) and the shuttling of soluble lithium polysulfides (LiPSs). To tackle these issues, we propose an efficient polysulfide regulation strategy via a functional separator coated with Bi2Se3@NiSe2 heterostructures anchored on nitrogen-doped carbon nanotubes (N-CNTs). The rationally constructed Bi2Se3@NiSe2 interfaces not only offer strong chemisorption toward LiPSs but also act as highly active electrocatalysts to facilitate their conversion kinetics, particularly the nucleation and decomposition of Li2S. Coupled with the three-dimensional conductive network of N-CNTs, which ensures rapid electron/ion transport, the designed separator significantly suppresses the shuttle effect and enhances redox efficiency. As a result, Li–S batteries equipped with the Bi2Se3@NiSe2/N-CNT-modified separator achieve a remarkable initial discharge capacity of 1418.24 mAh g–1 at 0.1 C and outstanding long-term cyclability with a minimal decay rate of 0.083% per cycle over 500 cycles at 1 C. In situ X-ray diffraction further verifies the reversible phase evolution between α-S8 and Li2S during cycling. This work highlights the potential of bimetallic selenide heterostructures as multifunctional catalytic interlayers and provides a feasible pathway toward advanced separators for durable Li–S batteries.

Oxygen vacancies (Ov) are crucial for modulating electronic structures and catalytic properties. Herein, a vacancy-rich HEDP-MoV heteropoly acid catalyst was synthesized via one-pot hydrothermal method by vanadium substituting molybdenum in phosphomolybdic acid with HEDP as support, focusing on Ov’s role in enhancing oxidative desulfurization (ODS) efficiency. XPS and EPR analyses showed vanadium incorporation (less electronegative than Mo) modulated Mo 5+ /Mo 6+ ratio and linearly increased Ov content from 28.65% (HEDP-Mo 10 V 2 ) to 41.81% (HEDP-Mo 7 V 5 ), promoting electron transfer and activity. The HEDP-MoV system exhibited superior H 2 O 2 activation and ·OH generation, with DBT desulfurization rate 41.6% higher than unsubstituted HEDP-Mo. The optimized HEDP-Mo 7 V 5 achieved 99.1% DBT desulfurization at O/S=3 and 30 o C (milder than most reported PMoV catalysts requiring O/S≥5) and retained 98% activity after 10 cycles. Radical quenching and EPR confirmed ·OH as dominant reactive species, while DFT verified H 2 O 2 dissociation thermodynamics. This study highlights vanadium substitution as an effective defect engineering strategy for HPA catalysts and provides a scalable pathway for mild-condition ultra-deep diesel ODS.

A simple carbothermal reduction–galvanic displacement route enables confined Ag–Bi heterostructures. • Dual Ag/AgCl–Bi/BiOCl conversion delivers 171 .0 mg g −1 Cl⁻ capture. • N,S-doped carbon confinement suppresses Ag dissolution below 0.03 mg L −1 . • Solvation-corrected DFT reveals Ag-enhanced Cl⁻ adsorption and charge transfer. • Stress buffering enables 88% capacity retention during prolonged cycling. Developing high-capacity and durable chloride-storage electrodes is crucial for selective electrochemical desalination. Herein, Ag and Bi nanoparticles were confined within an N, S-doped carbon framework (Ag, Bi@NSCx) through sequential carbothermal reduction and galvanic displacement. By integrating Ag/AgCl and Bi/BiOCl dual-conversion chemistry with conductive carbon confinement, the optimized Ag, Bi@NSC1 electrode enabled an asymmetric capacitive deionization system to deliver a high Cl⁻ capture capacity of 171.0 mg g −1 and a rapid initial removal rate of 40.45 mg g −1 min −1 . The electrode retained approximately 88% of its initial capacity after 50 adsorption–desorption cycles, and the dissolved Ag concentration remained below 0.03 mg L −1 , indicating limited metal leaching during prolonged operation. It also exhibited preferential Cl⁻ capture in multianion solutions and effectively desalinated saline–alkali agricultural drainage water. Solvation-corrected density functional theory calculations revealed that Ag incorporation strengthened Cl⁻ adsorption and induced a favorable charge redistribution across the Ag–Bi interface. Multiphysics simulations further demonstrated that the NSC framework mitigated the stress localization caused by the mismatched volume changes of the Ag/AgCl and Bi/BiOCl phases. The research establishes a dual-conversion and interfacial confinement strategy for achieving selective, high-capacity, and durable chloride capture.

The surface passivation deactivation and limited supply of Fe 2+ on nano zero-valent iron (nZVI, Fe 0 ) restrict activation of persulfate. Herein, L-cysteine modified cobalt-based ZIF derivative anchored Fe 0 (Fe 0 @ZIF-CoNS2) containing luxuriant oxygen vacancy (O v ) defects and bimetals was fabricated. The sintered bulk ZIF-CoNS2 and chain-shaped Fe 0 were disaggregated into rough and dispersed nanospheres, meanwhile, the loading of Fe 0 increased the specific surface area of ZIF-CoNS2 by 11 times. The peroxydisulfate (PDS) consumption efficiency of 96.11 % and the metronidazole (MNZ) removal efficiency of 96 % were achieved by the catalytic action of 0.18 g/L Fe 0 @ZIF-CoNS2. Compared than the unmodified system, the leaching concentrations of Fe and Co ions were reduced by 7.33 mg/L and 4.44 mg/L, respectively. The regulation of L-cysteine elevated the relative ratio of O v from 0.46 to 6.26 and augmented the electron transfer ability of precursor. Fe, Co and O v were identified as the main active sites, where O v played an important role as a medium in inducing sustainable generation of Fe 2+ /Co 2+ and 1 O 2 . The modified system fulfills the degradation of MNZ through plentiful 1 O 2 and scant free radical. This research offers insights into the formation of O v and enhancement of nZVI reactivity during advanced oxidation processes.

A flower-like S, N-codoped carbon nanosheets loaded with hybrid magnetic nanoparticles (HMNPs/S,N-CNSs) by using MOF as precursor was prepared. The morphology, composition, microstructure, and property were evaluated by SEM, HRTEM, EDS, XRD, XPS, magnetic analysis, and cyclic voltammetry. The hybrid nanoparticles were composed of most Fe 3 O 4 , some CoFe alloy, and a few Fe 2 S. The magnetic material showed high magnetism and brilliant electrocatalysis towards the electrochemical reduction of antibiotic nitrofurazone (NFZ). By utilizing screen-printed electrode (SPE) and HMNPs/S,N-CNSs, a disposable electrochemical NFZ sensor (HMNPs/S,N-CNSs/SPE) was fabricated by magnetic control. The current signal of NFZ at HMNPs/S,N-CNSs was 6.38 times higher than that of bare SPE. It displayed a wide detection range of 0.01–50 μM with a detection limit of 4.2 nM (S/N = 3). The practical applicability of the sensor in real samples presented satisfactory results. The disposability, low cost, high sensitivity, low consumption volume in analyses, and good selectivity make the proposed sensor a promising tool for NFZ detection.

Precise engineering of interfacial electron transfer is pivotal for advancing photocatalytic performance. Herein, a metallic Bi-bridged, Bi-vacancy-rich Bi@Bi V -Bi 2 O 3 /CN S-scheme heterojunction featuring orchestrated interfacial charge transport is designed. Bi vacancies in Bi 2 O 3 acts as an efficient hole extraction agent, driving the directional migration of photogenerated holes, while the in-situ generated metallic Bi establishes a rapid electron transfer channel via Bi C interfacial bonding to concentrate electrons onto the CN substrate. Notably, the p-orbital hybridization of Bi with the p orbitals of C modulates the local electronic structure, synergistically enhancing interfacial electron dynamics. X-ray absorption spectroscopy confirms the formation of Bi C with strong electronic coupling, while density functional theory (DFT) calculations reveal directed charge migration at the Bi@Bi V -Bi 2 O 3 and CN interfaces. This dual-channel synergistic mechanism achieves highly efficient spatial separation of charge carriers while preserving highly reductive electrons and highly oxidative holes, providing an ideal platform for photocatalytic hydrogen evolution and organic pollutant degradation. Benefiting from the engineered interfacial pathways, Bi@Bi V -Bi 2 O 3 /CN achieves superior photocatalytic degradation of antibiotic, with a tetracycline (TC) degradation rate constant (0.019 min −1 ) and a hydrogen production rate (2903.30 μmol g −1 h −1 ) reaching 5.8 and 12.1 times that of pristine CN, respectively. This work provides novel insights and a theoretical foundation for designing efficient S-scheme photocatalysts with dual-functional capabilities for pollutant degradation and clean energy production.

Sulfides-based all-solid-state lithium batteries show great potential due to their high safety and high energy density, yet severely suffer from sulfide electrolytes/Li interfacial instability and short cycle life. Here we propose a Li-In-S composite foil comprising Li 2 S, Li x In, and LiInS 2 to stabilize the Li/Li 6 PS 5 Cl interface by constructing built-in electric fields, thereby enabling long-life all-solid-state lithium batteries. The work function difference between Li 2 S and Li x In generates built-in electric fields at the heterointerface, which traps the interfacial electrons and restricts their transfer to Li 6 PS 5 Cl, thereby suppressing the interfacial side reactions. Simultaneously, the built-in electric fields promote Li + adsorption and diffusion inhibiting lithium dendrite growth. Li symmetrical cells display high critical current density over 4 mA cm −2 and Li plating/stripping stability over 2000 h at 1 mA cm −2 . The assembled full cells with LiCoO 2 and LiNi 0.8 Co 0.1 Mn 0.1 (NCM811) demonstrate high capacity retention of 93% over 2000 cycles at 1 C and 87.7% over 1000 cycles at 1 C, respectively. Moreover, Li-In-S|Li 6 PS 5 Cl|NCM811 full cell shows rate capability up to 4 C. This work offers useful insights into the design of stable interfaces in all-solid-state batteries.

Photocatalytic CO₂ reduction is a promising route for solar fuel production, yet it is often hampered by inefficient charge separation and compromised redox power in conventional heterojunctions. Here, we report a thermal-mediated strategy that intelligently reconfigures the charge transfer pathway in In 2 O 3 /BiOCl heterojunctions from a conventional Type-II to a S-scheme. This transition is driven by the in situ formation of synergistic dual defects—oxygen vacancies and metallic bismuth—enabled by precise solvothermal control. The oxygen vacancies serve as efficient CO 2 adsorption and activation sites, while metallic Bi functions as effective electron bridges. This defect synergy collectively reconstructs the interfacial electronic structure, as directly evidenced by in situ XPS and EPR and confirmed by DFT calculations, which reveal a reversed band alignment conducive to S-scheme charge flow. The resulting S-scheme In 2 O 3 /BBC-Ov heterojunction (InBBC-4) achieves a superior CO production rate of 96.11 μmol g −1 h −1 with 96.7 % selectivity, substantially outperforming its Type-II counterpart. This work offers profound atomic-level insights and establishes a simple thermal-tuning paradigm for designing high-performance photocatalysts through defect-mediated control of charge pathways.

The functionalization of metal–organic frameworks (MOFs) has been considered an effective strategy for promoting heavy metals removal from water. Therefore, a novel post coordination modulation method was systematically studied to synthesize ZIF-8 functionalized by 2,5-Dimercapto-1,3,4-thiadiazole (Post-ZIF-8-DMTD) for trace heavy metals removal from drinking water. The effects of addition time and addition amount of DMTD on the structure and adsorption performance of Post-ZIF-8-DMTD were investigated. It was found that addition time of DMTD had minor impact, while addition amount of DMTD had great impact, appropriate DMTD addition amount (375 mg) could not only provide sufficient active sites but also avoid self-polymerization of DMTD. Post-ZIF-8-DMTD exhibited a more regular structure than Before-ZIF-8-DMTD synthesized by direct coordination of mim and DMTD with Zn 2+ , and had faster adsorption rate and deeper purification capability for trace Pb(II). Post-ZIF-8-DMTD also exhibited good stability, wide suitable pH range, high maximum adsorption capacity (4.34 mg/g) that met WHO effluent Pb(II) concentration standard and excellent capture capacity for many trace heavy metals in tap water, and could be regenerated effectively with thiourea solution. The post coordination modulation method provides a novel and efficient strategy for the functionalization of MOFs, and Post-ZIF-8-DMTD has excellent application prospects in drinking water purification.

A novel nanoprobe based on S,O-doped carbon nitride quantum dots (S,O-CNQDs) was designed and synthesized. The as-prepared S,O-CNQDs exhibits good biocompatibility and strong fluorescence at excitation 360 nm. It is found that folic acid (FA) could efficiently quench the fluorescence of S,O-CNQDs. The obtained S,O-CNQDs is capable of acting as a sensitive and selective probe for FA detection in the range 5.0–83.3 μM with a detection limit of 90 nM. The as-prepared probe has been successfully utilized for the detection of FA in various real samples with satisfactory recoveries (98.8–107 %) and small relative standard deviation (<5%). The reaction mechanism between S,O-CNQDs and FA has been discussed. In addition, FA-S,O-CNQDs formed through a classical cross-linking reaction between FA and S,O-CNQDs easily accesses and penetrates into HepG2 cells with high folate receptors expression. FA-S,O-CNQDs with low cytotoxicity and good biocompatibility shows great potential in FA detection and targeted imaging of cancer cells.

Lithium–sulfur (Li–S) batteries have been limited by their poor electrochemical performance due to the large volume change and severe shuttle effect during cycling. Binders serve as an essential role in sulfur electrodes and can stabilize the mechanical integrity of the electrode. It also has been demonstrated that designing strong-affinity binders is a feasible and facile method to suppress the shuttle effect. Therefore, in this work a strong-affinity elastic network binder is designed for high-performance Li–S battery coupling with tannic acid (TA) and polyurethane (PU). Firstly, the rich hydrogen bonds between TA and PU result in a mechanically robust network to keep the sulfur electrode from cracking in the cycling process. Secondly, the selected TA with abundant phenolic hydroxyl groups possesses strong adsorption capability toward polysulfides, which can efficiently restrain the shuttle effect. Hence, the cycling stability of Li–S batteries using P1T1 binder is significantly improved, maintaining the capacity of 602.5 mAh g–1 after 500 cycles at the current density of 0.5 C.

Oxychalcogenides capable of exhibiting excellent balance among large second-harmonic generation (SHG) response, wide band gap ( E g ), and suitable birefringence (Δ n ) are ideal materials class for infrared nonlinear optical (IR NLO) crystals. However, rationally designing a new high-performance oxychalcogenide IR NLO crystal still faces a huge challenge because it requires the optimal orientations of the heteroanionic groups in oxychalcogenide. Herein, a series of antiperovskite-type oxychalcogenides, Ae 3 Q[GeOQ 3 ] (Ae = Ba, Sr; Q = S, Se), which were synthesized by employing the antiperovskite-type Ba 3 S[GeS 4 ] as the structure template. Their structures feature novel three-dimensinoal frameworks constructed by distorted [QAe 6 ] octahedra, which are further filled by [GeOQ 3 ] tetrahedra to form antiperovskite-type structures. Based on the unique antiperovskite-type structures, the favorable alignment of the polarizable [GeOQ 3 ] tetrahedra and distorted [QAe 6 ] octahedra have been achieved. These contribute the ideal combination of large SHG response (0.7–1.5 times that of AgGaS 2 ), wide E g (3.52–4.10 eV), and appropriate Δ n (0.017–0.035) in Ae 3 Q[GeOQ 3 ]. Theoretical calculations and crystal structure analyses revealed that the strong SHG and wide E g could be attributed to the polarizable [GeOQ 3 ] tetrahedra and distorted [QAe 6 ] octahedra. This research provides a new exemplification for the design of high-performance IR NLO materials.
