2,2′,4,4′-tetrabromodiphenyl ether (BDE-47) is a highly toxic organic pollutant. Owing to the high structural stability, BDE-47 is difficult to be naturally decomposed. In this study, Au nanoparticles decorated flower-like ZnIn 2 S 4 microspheres were successfully fabricated and applied for the rapid removal of BDE-47 driven by visible-light irradiation. It was revealed that 3 wt% Au-loaded ZnIn 2 S 4 (Au/ZnIn 2 S 4 ) has the highest removal rate for BDE-47 (0.90118 h −1 ). A study of the reaction path and mechanism shows that the bromine adjacent to the oxygen atom in BDE-47 tends to be removed via electron transfer. This is attributed to the band-gap excitation of ZnIn 2 S 4 , the surface plasmon resonance effect of the Au nanoparticles, and the Schottky junctions between them. Furthermore, density functional theory calculations show that the strong affinity between Au 0 and the bromine atom adjacent to the oxygen atom in BDE-47 can lengthen the carbon–bromine bond and further weaken the bond upon the accumulation of electrons. This may be the main reason for the rapid debromination of BDE-47. This study provides a new perspective on the photocatalytic removal of moderately brominated polybrominated diphenyl ethers.

How to achieve high-speed directional migration and separation of photogenerated carriers at heterointerfaces is still an important factor restricting efficient photocatalytic reactions. Herein, hierarchical columnar ZnIn 2 S 4 /BiVO 4 (ZIS/BVO) Z-scheme composite with photogenerated carriers highway in heterogeneous interface are designed by an in situ technique. Ultrathin ZIS nanosheets are uniformly grown upright on the surface of mulberry-like BVO pillars. The confined built-in electric field and Z-scheme heterojunction in ZIS/BVO are verified in detailed by synchronous illumination X-ray photoelectron spectroscopy, theoretical calculation, electron spin resonance spectroscopy, and high-resolution TEM. The photogenerated electrons in the conduction band (CB) of BVO migrate to the valence band (VB) of ZIS through heterojunction, whereas holes in the VB of BVO and electrons in the CB of ZIS maintain the original high redox capability. These holes and electrons with high redox capability react with H 2 O and O 2 to generate more OH and O 2 − , respectively, achieving enhanced photocatalytic mineralization antibiotic properties. The mineralization rate of antibiotics in the optimized ZIS/BVO material are 4.4 and 1.8 times higher than that of pure BVO and ZIS, respectively.

As an important heptapeptide toxin, microcystine-LR (MC-LR) has attracted extensive attention because of its great harm to animals, plants and plankton in water. Therefore, an ultrasensitive photoelectrochemical aptasensor based on ZnIn 2 S 4 /CdSe heterojunction was disigned to monitor MC-LR. In this strategy, the ZnIn 2 S 4 /CdSe heterojunction with matching energy levels was used as the substrate of the aptasensor. By reason of the effective separation of electrons and holes, the heterojunction exhibited wide light absorption region and increased light utilization rate, resulting in a higher electrical signal. The specific recognition of MC-LR depend on the precise binding with aptamer, which modified on the electrode through base complementary pairing. In the presence of MC-LR, MC-LR was specific recognized by MC-LR aptamer, the photocurrent signal amplifier Bi 2 S 3 was released from the aptasensor electrode, leading to a decreased photocurrent. The designed photoelectrochemical aptasensor showed an ultrasensitive detection for MC-LR with a wide response range from 10 -1 to 10 -8 µM, and lower detection limit of 0.55 × 10 -8 µM (3σ/S).

Coupling with bimetallic nanoparticles (NPs) has been considered as a promising strategy to enhance photocatalytic hydrogen evolution (PHE) efficiency of semiconductor photocatalysts and simultaneously minimize the use of expensive noble metals. Herein, we firstly synthesized spherical-like ZnIn 2 S 4 (ZIS) by a solvothermal method, and then combined with nickel/palladium (denoted as NiPd) bimetallic NPs to form NiPd bimetal/ZIS Schottky heterojunction. The chemical states of NiPd NPs were confirmed in the form of NiPd bimetal rather than Ni–Pd alloy. The detailed characterization results demonstrated that the deposition of NiPd bimetal played a major role in increasing light harvesting capacity, accelerating charge carrier (electrons and holes) separation and facilitating photogenerated electrons transfer, leading to the boosted PHE performance in NiPd-ZIS photocatalysts. By adjusting Ni:Pd molar ratio in Ni x Pd y -ZIS photocatalysts, the desired sample of Ni3Pd7-ZIS exhibited the highest PHE efficiency (106.6 µmol/h) and apparent quantum yield (AQY) value of 40.22% at 400 nm under visible light as compared to ZIS, Ni-ZIS and Pd-ZIS. The multiple techniques were performed to deeply investigate the photogenerated charge carrier separation, transfer and recombination. The possible mechanism over Ni3Pd7-ZIS sample for boosting PHE performance was presented based on characterization results. On the whole, this work would provide some insights into the development of cost-effective and high-efficiency bimetallic cocatalyst-based photocatalysts.

Novel sandwich-like ZnIn 2 S 4 /Ti 3 C 2 composites with strong interfacial coupling were prepared by a facile solvothermal approach for U(VI) photocatalytic reduction immobilization. The integration of Ti 3 C 2 nanosheets into ZnIn 2 S 4 hierarchical structures endowed the composite outstanding photocatalytic performance through improving the utilization of solar energy and boosting the separation of photogenerated electrons and holes, evidenced by a fast reaction rate of 0.0247 min −1 , which was 3.20 times of that for pristine ZnIn 2 S 4 . The corresponding U(VI) removal efficiency of 50 ppm U(VI) solution reached 96.1% under visible light irradiation without sacrificial agents. In addition, the excellent stability and reusability of ZnIn 2 S 4 /Ti 3 C 2 has been demonstrated.

Structure manipulation of photocatalysts at an atomic scale is a promising way to improve its photocatalytic performance. Herein, we realize the anchoring of single Ni atoms on the ZnIn 2 S 4 nanosheets with rich sulfur vacancies. Experimental results demonstrate that single Ni atoms induce the formation of Ni-O-M (Zn/In) atomic interface, which can efficiently promote the carriers separation and prolong the carrier life time. In addition, in situ electron spin resonance spectroscopy (ESR) confirms that the single Ni atoms act as an electron trapping center for protons reduction. As a result, the single Ni atoms decorated ZnIn 2 S 4 nanosheets with rich sulfur vacancies (Ni/ZnIn 2 S 4 -RV s ) shows a hydrogen evolution rate up to 89.4 μmol h −1 , almost 5.7 and 2.3 times higher compared to that of ZnIn 2 S 4 nanosheets with poor sulfur vacancies and rich sulfur vacancies (denoted as ZnIn 2 S 4 -PV s and ZnIn 2 S 4 -RV s ). This work opens up a new perspective manipulating the single-atom cocatalyst and sulfur vacancy on sulfide supports for improving photocatalytic hydrogen evolution.

The photocatalytic coupling reaction can be conducted in one pot to realize the simultaneous utilization of electrons and holes, thereby obtaining value-added fine chemicals and fuels. Herein, we report a binary nickel modified ZnIn 2 S 4 (Ni:ZIS) for highly efficient photocatalytic selective oxidation of benzyl alcohol (BA) to benzaldehyde (BAD) integrated with hydrogen (H 2 ) evolution, in which Ni can promote photogenerated charge transfer for enhancing photoactivity. Particularly, the products of converting BA to aromatic compounds over blank ZnIn 2 S 4 (ZIS) and Ni:ZIS show a marked difference under the same reaction conditions. Hydrobenzoin (HB) is the primary product over blank ZIS. After the introduction of Ni, the formation of HB is dramatically suppressed, resulting in higher selectivity of BAD, because the introduction of Ni facilitates the α-H abstraction. In addition, an analogous phenomenon has been observed on Ni-based compounds modified ZIS, such as Ni x P and NiS. It is hoped that this work would provide a feasible paradigm for modifying the surface of photocatalysts to tune the selectivity of product-oriented alcohols oxidation coupled with H 2 evolution in water.

A facile synthetic route, by using rhombic dodecahedral zeolitic imidazolate framework-8 (ZIF-8) as the structure template, is devoted to fabricating the ZnS/ZnIn2S4 hybrid heterojunction; the compact heterostructure was produced by combining the sulfurization of ZIF-8 and the in situ precipitation of ZnIn2S4 in one pot. The resulting ZnS nanoparticles of about 100 nm were uniformly dispersed in the folds of flower-like ZnIn2S4, whose structure is beneficial for charge transfer at the heterointerface. The additional quantities of ZIF-8 are varied to find an optimum ratio of the two components to obtain the best photocatalytic activity. In the photocatalytic hydrogen generation irradiated by simulated solar light, all the ZnS/ZnIn2S4 hybrid photocatalysts displayed improved hydrogen production rates compared to single ZnS or ZnIn2S4, and the best hydrogen production rate of 453.4 μmol h−1 g−1 is obtained by ZnS/ZIS-20, whose value is approximately 4 times higher than that of single ZnIn2S4. The electrochemical properties of the ZnS/ZnIn2S4 hybrid photocatalysts were measured to explore the charge transfer mode at the interface, and the band structure and enhanced photocatalytic hydrogen generation mechanism have been proposed. The excellent recycling properties of hydrogen production indicated the prospective applications of this kind of ZIF-derived metal sulfide in photocatalytic reactions.

A comprehensive study of degradation efficiency and transformation pathways derived from photocatalytic degradation of five antibiotics including tetracycline hydrochloride, chloramphenicol, rifampicin, lincomycin hydrochloride and erythromycin on ZnIn 2 S 4 under visible light irradiation was investigated. All the five antibiotics cannot be detected after 90 min photocatalytic degradation by ZnIn 2 S 4 . The calculated pseudo-first-order constants (k r ) were in the order of tetracycline hydrochloride (0.0858 min −1 ) > erythromycin (0.0846 min −1 ) > lincomycin hydrochloride (0.0285 min −1 ). However, degradation of rifampicin and chloramphenicol cannot be described by pseudo-first-order reaction kinetics. The electron paramagnetic resonance (EPR) results indicated that the main reactive oxygen species in this study was superoxide radical ( O 2 - ) and minor active species was hydroxyl radical ( OH). Thirty-four, thirty, twenty, sixteen and eighteen kinds of intermediate species were identified by LCMS-IT-TOF during the 180 min photocatalytic degradation of rifampicin, erythromycin, chloramphenicol, lincomycin hydrochloride and tetracycline hydrochloride, respectively. The proposed photocatalytic degradation pathways provided detailed evolution process of five antibiotics, which would be meaningful for the researches on transformation behavior of antibiotics.

Photocatalytic lignin valorization has garnered significant interest because of its mild reaction conditions and high selectivity. However, the unclear relationships among photocatalysts, reaction solvents, and catalytic activities have hindered further exploration. Herein, we report the innovative synthesis of sulfur vacancy-rich MoS2@ZnIn2S4 heterostructures through one-pot sulfidation of Mo-based metal–organic frameworks (MOFs) for efficient photocatalytic lignin depolymerization. The Mo-MOF-derived MoS2 provides a large surface area and high porosity, enhancing mass transfer, whereas the sulfur vacancies on ZnIn2S4 promote effective charge carrier separation. Notably, the presence of water in the reaction solvent enables the sulfur vacancies to efficiently adsorb and activate water molecules, facilitating proton generation from water dissociation for selective lignin Cβ–O bond hydrogenolysis. The bond cleavage efficiency exhibits a volcano-type trend with increasing water content, achieving optimal performance with 100% conversion of the lignin model compound 2-phenoxy-1-phenylethanol, yielding 78% phenol and 89% acetophenone. This performance significantly surpasses those of MoS2, ZnIn2S4, and the sulfur vacancy-poor MoS2@ZnIn2S4. This work provides critical insights into the solvent-dependent reactivity of catalysts in lignin depolymerization and underscores the potential of defect engineering in photocatalytic biomass valorization.

A sulfide–sulfide ZnIn 2 S 4 /ZnS heterojunction establishes an S-scheme charge-transfer pathway with intimate interfacial coupling. • Ce act as additional regulation centers to modulate interfacial electronic structure and carrier dynamics. • The S-scheme charge-transfer mechanism is supported by XPS, KPFM, DFT calculations, and ultrafast spectroscopy. • Ce-mediated electronic regulation synergistically enhances CO 2 adsorption, activation, and surface reduction kinetics. • The optimized C2ZZ2 catalyst achieves 140.6 μmol g −1 h −1 CO production through coordinated interface and electronic regulation. Solar-powered photocatalytic CO 2 reduction represents a promising strategy for achieving carbon neutrality through sustainable solar-to-chemical energy conversion. Nevertheless, inefficient charge separation and sluggish interfacial reaction kinetics markedly limit its performance. Herein, Ce-regulated ZnIn 2 S 4 /ZnS S-scheme heterojunctions were synthesized via a facile one-step in situ hydrothermal strategy to regulate interfacial charge transfer and surface reaction processes. The ZnIn 2 S 4 /ZnS interface establishes an S-scheme charge-migration pathway, facilitating directional migration and utilization of photogenerated carriers, while Ce incorporation induces electronic redistribution and modulates the local electronic environment. Experimental investigations combined with theoretical calculations reveal that Ce-mediated electronic modulation cooperates with the S-scheme heterointerface to strengthen CO 2 adsorption, accelerate interfacial charge transfer, and reduce the energy barrier of CO 2 reduction. Benefiting from this synergistic electronic regulation, the optimized C2ZZ2 catalyst achieves a CO evolution rate of 140.6 μmol g −1 h −1 , approximately 4.5-fold higher than pristine ZnIn 2 S 4 . This work provides mechanistic insights into rare-earth-mediated electronic regulation in metal sulfide photocatalysts, offering a deeper understanding of the relationship among electronic modulation, interfacial charge-transfer dynamics, and CO 2 reduction kinetics. An S-scheme heterojunction, in which ZnS nanospheres are anchored to a defect-containing cerium-doped ZnIn 2 S 4 micro-flowers structure (CxZZy composite), was synthesized via a one-step in situ solvothermal method. This material exhibits outstanding CO 2 catalytic performance under visible light irradiation. Download: Download high-res image (118KB) Download: Download full-size image

To address the challenges of insufficient near-infrared light utilization and rapid charge recombination in traditional photocatalysts, this study designed and synthesized a hollow-structured Cu 2−x S@ZnIn 2 S 4 S-scheme heterojunction with synergistic photothermal-photocatalytic properties. The synergistic mechanism between plasmonic photothermal effects and heterojunction charge-transfer in broad-spectrum catalysis was systematically elucidated. Experimental results demonstrated that the composite achieved a hydrogen evolution rate of 32.58 mmol g −1 h −1 under AM 1.5G irradiation without cooling water (WCW), which is 3.00 times that of pure ZnIn 2 S 4 . Moreover, the solution temperature reached 47.4 °C under near-infrared (NIR) illumination. Theoretical analysis revealed that the localized surface plasmon resonance (LSPR) of Cu 2−x S extended light absorption into the NIR region and generated a photothermal effect. Meanwhile, the S-scheme band alignment, together with multiple light scattering induced by the hollow structure, synergistically optimized carrier separation and promoted directional charge migration. The catalyst exhibited excellent stability over 750 min and demonstrated measurable NIR-driven activity at wavelengths above 800 nm. By coupling band-engineering with photothermal conversion, this work provided a theoretical foundation and a material prototype for designing efficient full-spectrum solar-to‑hydrogen conversion systems, showing clear application potential in photothermal-assisted artificial photosynthesis.
