The S-doped Sb 2 O 3 nanocrystals were successfully synthesized using SbCl 3 and thioacetamide (TAA) as precursors via a facile one-step hydrothermal method. The effects of pH of the precursor reaction solution on the product composition and property were determined. The results indicated that the doping amount of S could be tuned by adjusting the pH of the precursor solution. Furthermore, the S entered into the interstitial site of Sb 2 O 3 crystals as S 2− , which broadened the absorption wavelength range of the Sb 2 O 3 nanocrystal. The S-doped Sb 2 O 3 exhibited an excellent visible-light-driven photocatalytic activity in the decomposition of methyl orange and 4-phenylazophenol. Last, a possible photocatalytic mechanism of the S-doped Sb 2 O 3 under visible light irradiation was proposed.

Considering the efficient utilization of resources and the simultaneous detection of multiple analytes, achieving selective detection of diverse analytes on one fluorescent covalent organic framework (COF) is of great significance. Herein, a carboxyl-carbazole-rich fluorescent COF (COF-DABT) was strategically synthesized using 3,6-diamino carbazole, capable of forming halogen bonds with analytes, and 2,5-bis(4′-formylphenyl) terephthalic acid, rich in carboxyl groups, which interacts with various analytes and adjusts fluorescence performance via its electron-withdrawing properties. The introduction of carbazole imparts fluorescence to COF-DABT through the intramolecular charge transfer (ICT) effect, while enabling selective fluorescence quenching. Specifically, the ICT of carbazole can be disrupted via linear halogen bond interactions with TBBPS, resulting in selectively detection of TBBPS in a fluorescence-off mode. Furthermore, efficient enrichment of TBBPS is facilitated by halogen bonds with carbazole and hydrogen bonds with carboxyl groups on COF-DABT. Selective fluorescence quenching of COF-DABT by Fe 3 + is achieved through chelating effect around carboxyl group, as well as cation-π interaction with carbazole benzene ring. This enables high selectivity detection of Fe 3+ via a fluorescence-off mode. Additionally, Fe 3+ can be reduced by ascorbic acid through REDOX reaction, mitigating interference with TBBPS detection and facilitating fluorescence-off-on mode detection of AA. Besides, rich carboxyl groups on COF-DABT exert a negative regulatory effect on the carbazole ICT mechanism. To counter this, D/L-Arg, with a size complementary to the adjacent carboxyl groups on COF-DABT, is introduced. Hydrogen bond interactions between D/L-Arg and carboxyl groups reduce the negative regulatory effect, allowing fluorescence enhancement for highly selective detection of D/L-Arg. Through rational design and functional optimization of fluorescent COF structures, multi-mode detection methods enable simultaneous detection of different analytes, achieving the goal of "one stone, several birds."

Nowadays, the electrocatalytic regulation mechanism of quantum dots (QDs)-supported materials is limited to strong metal-support interaction (SMSI) and electron-metal-support interaction (EMSI). However, the lattice strain of the carrier induced by QDs is neglected, which is not conducive to the directional design of the QDs-supported electrode and the establishment of its structure-performance correlation. Given these, the size and distribution of Pt QDs controlled by electrodeposition effectively regulate the strain degree on S-NiFeP nanosheets. DFT results reveal that Pt@S-NiFeP/NF complies with a Fe-Pt dual active sites mechanism for alkaline HER, and a Fe active site mechanism for OER. Interestingly, the compressive strain in the S-NiFeP substrate effectively promotes the d‐band center shift and the energy barrier reduction, thereby optimizing the alkaline HER and OER kinetics. As expected, Pt@S-NiFeP/NF with appropriate strain owns alkaline HER and OER performance at 1 A cm −2 that exceeds the commercial Pt/C and RuO 2 . Overall, this work has guided the structural design of the 'noble metal QDs@carrier' model and laid a foundation for its application at ampere-level current densities.

At present, the rapid, sensitive, and highly selective detection of trace organic contaminants is a research spot in the field of environment. Herein, a novel fluorescent nanoprobe N, S-CDs@MIP based on N/S co-doped carbon quantum dots (CDs) coupled with amoxicillin molecularly imprinted polymer was synthesized. The fluorescent property of N, S-CDs@MIP and fluorescence quenching level of amoxicillin to N, S-CDs@MIP was explored. Furthermore, the fluorescence analysis method based on N, S-CDs@MIP probe for quantitatively detecting amoxicillin was established. The synthesized N, S-CDs@MIP has a maximum fluorescence emission wavelength of 440 nm and a significantly selective fluorescence response toward amoxicillin with a large imprinting factor of 4.07. For the developed fluorescence analysis method, the detection limit, the linear range of the standard curve, and relative standard deviation (RSD) were obtained as 1.17 ng/mL, 5.8–200 ng/mL, and <3 %, respectively. The real environmental water samples were measured with a high accuracy with the recovery of 83.6 % ~ 104.7 % and RSD of 2.3 % ~ 5.1 %. Compared to the HPLC-UV, HPLC-MS, and the fluorescence detection method based on CDs or doped CDs, the established fluorescence detection method exhibits high selectivity, wide linear range, and low detection limit. It is greatly promising in the quick detection of trace amoxicillin.

Hydrogen production via photocatalytic water splitting holds great promise for efficient solar energy conversion. While ZnIn₂S₄ (ZIS) exhibits a suitable band structure for visible-light-driven hydrogen production, its practical application is significantly limited by low charge separation efficiency and poor stability. This work pioneers an acousto-hydrothermal strategy utilizing high-frequency ultrasonic atomization to synthesis structurally optimized ZIS. Systematic characterization reveals that ultrasonic cavitation compresses crystal lattices to enhance Zn 3d-S 3p orbital hybridization, assembles nanosheets with a 20 % increased surface area, leading to enhanced charge separation efficiency. The optimized ZIS demonstrates significantly enhanced photocatalytic activity and stability. It achieves a remarkable hydrogen evolution rate of 51.8 mmol g⁻¹ h⁻¹ under 455 nm visible light irradiation, representing an 86 % improvement over pristine ZIS. After a 15 h reaction, the catalytic system produces 8.3 mmol of H₂ (185.9 mL at standard conditions). This work presents an innovative strategy for designing nanosheet-based materials to achieve high-efficiency photocatalytic hydrogen evolution.

Photocatalytic hydrogen evolution represents a promising strategy for sustainable energy conversion, yet its efficiency is often limited by the rapid recombination of photogenerated carriers and insufficient redox capabilities. In this work, an S-scheme ZnMn 2 O 4 /CdO (ZMO/CdO) heterojunction was successfully fabricated via a simple solvothermal method to address these challenges. Based on band structure analysis, the composite satisfies the thermodynamic prerequisites for photocatalytic hydrogen evolution. The establishment of an S-scheme charge transfer pathway, driven by the combined effect of an internal electric field (IEF) and band bending, enables photogenerated electrons (e − ) to accumulate in the conduction band (CB) of ZnMn 2 O 4 (ZMO), while holes (h + ) are retained in the valence band (VB) of CdO. This mechanism not only promotes the spatial separation of photogenerated electron–hole pairs (PEHP) but also preserves the strongest redox ability of the system. Under optimized conditions (pH = 8 with triethanolamine (TEOA)), the ZMO/CdO composite achieves an outstanding hydrogen evolution rate of 2237 μmol∙g −1 ∙h −1 , which is approximately 4.38 and 2.84 times higher than that of pure CdO and ZMO, respectively. Moreover, the photocatalyst maintains high hydrogen production activity and structural stability in diverse real water samples, including municipal water, natural surface water, and even wastewater, highlighting its strong potential for practical solar-driven hydrogen production in complex environments.

In this work, an agarose-polyacrylamide hydrogel electrolyte (APE) with an interpenetrating and hierarchically porous network is introduced to reconstruct solvation and interface dynamics for a high-performance Zn-S batteries. This structure results in a high ionic conductivity of 42.1 mS cm −1 and a Zn 2+ transference number of 0.64. Molecular dynamics reveal that most H 2 O and SO 4 2− are excluded from the outer Helmholtz plane, forming an optimized electric double layer on Zn surface. Consequently, a prolonged 1200 h Zn plating/stripping behavior is obtained with 1 mAh cm −2 at 1 mA cm −2 , and a high Zn plating of 20 mAh cm −2 at 5 mA cm −2 . Furthermore, APE modulates the nucleation mode of ZnS, converting the originally sluggish and non-uniform progressive nucleation into a rapid and uniform instantaneous nucleation. As a result, this hydrogel Zn-S batteries deliver a capacity of 895 mAh g −1 and 91% capacity retention within 300 cycles at 5 A g −1 .

The accelerating demand for sustainable, high-rate, and durable energy storage underscores the need for carbon electrodes that simultaneously offer balanced micro–mesoporosity for rapid ion transport and robust heteroatom functionalities for enhanced interfacial chemistry. In the present work, we convert bitumen asphaltenes and recycled cellulose acetate into N/S co-doped hierarchical carbons via ammonium persulfate-assisted co‑carbonization and KOH activation. The optimized carbon combines an ultrahigh specific surface area of 3527 m 2 g −1 , balanced micro–mesoporosity, and uniformly distributed electroactive N/S species (pyridinic/pyrrolic N, C S, SO x ), enhancing conductivity and pseudocapacitance. In three-electrode tests, the electrode delivered 382.5 F g −1 at 0.5 A g −1 with 74% retention at 10 A g −1 . The symmetric aqueous device achieved a specific capacitance of 288.2 F g −1 at 0.5 A g −1 , energy densities of 10.01 Wh kg −1 at 257.4 W kg −1 and 5.42 Wh kg −1 at 6728.3 W kg −1 , and 108.7% capacitance retention after 10,000 cycles at 5 A g −1 . This study advances sustainable energy storage by enabling low-cost, high-performance supercapacitors and promoting solid-waste recycling.

Partial cation substitution is an effective way to inhibit defects and carrier recombination, which can improve the efficiency of Cu 2 ZnSn(S,Se) 4 (CZTSSe) solar cells. Herein, flexible Cu 2 Zn 1− x Cd x Sn(S,Se) 4 ( x = 0–15%) solar cells are fabricated on Mo foils with partial Cd substitution for Zn via a green solution-process. The best device performance can be achieved when Cd/(Zn + Cd) = 8%, with an efficiency up to 6.49% and a significantly improved device repeatability. The E U decreases from 24 to 15 meV, indicating that antisite defects and band tailings are effectively suppressed. C – V data reveal that W d and V bi are enhanced after doping Cd, resulting in a stronger built-in electric field which facilitates Fermi-level splitting and hence increases band bending of the absorber toward the junction interface. Furthermore, the mechanism of current shunting is studied using an equivalent circuit model with three parallel current pathways to fit J – V curves. The key parameters for the solar cell diode such as A , J 0 , and R sh are significantly improved by partially substituting Zn with Cd, demonstrating that current shunting loss is suppressed and the junction quality is improved, resulting in a significant improvement in device repeatability.

Novel biodegradable amphiphilic graft copolymers containing hydrophobic poly(ester-carbonate) backbone and hydrophilic poly(ethylene glycol) (PEG) side chains were synthesized by a combination of ring-opening polymerization and “click” chemistry. First, the ring-opening copolymerization of 5,5-dibromomethyl trimethylene carbonate (DBTC) and ε-caprolactone (CL) was performed in the presence of stannous octanoate [Sn(Oct) 2 ] as catalyst, resulting in poly(DBTC- co -CL) with pendant bromo groups. Then the pendant bromo groups were completely converted into azide form, which permitted “click” reaction with alkyne-terminated PEG by Huisgen 1,3-dipolar cycloadditions to give amphiphilic biodegradable graft copolymers. The graft copolymers were characterized by proton nuclear magnetic resonance ( 1 H NMR), Fourier transform infrared spectra and gel permeation chromatography measurements, which confirmed the well-defined graft architecture. These copolymers could self-assemble into micelles in aqueous solution. The size and morphologies of the copolymer micelles were measured by transmission electron microscopy and dynamic light scattering, which are influenced by the length of PEG and grafting density. © 2011 Wiley Periodicals, Inc.

In this work, the superconducting properties of FeSe 1−x S x with 0 ≤ x ≤ 0.5 were studied. With S doping, T c is enhanced and shows a dome shape in the studied composition range. XRD measurements demonstrate that S substituting Se sites introduces positive chemical pressure, which can suppress the orbital ordering, manifesting as the decrease of T s . Hall measurements demonstrate that S doping can effectively tune the charge carriers and make hole-type carriers predominant. However, no maxing T c is obtained as T s vanishes in FeSe 0.7 S 0.3 , indicating the nematic order has no universal influence on the superconductivity of FeSe system.
