Multiplex modification is considered as one of attractive methods to achieve highly-efficient photocatalytic water splitting into hydrogen evolution performance. Herein, MoS 2 /S v -ZnIn 2 S 4 /ZnS (MS/S v -ZIS/ZS) composites were constructed by a facile in-situ engineering technique. The sulfur vacancy, Ohmic-type contact and I-type heterojunction were systematically integrated into the composites. The unique structure could not only facilitate a directional charge transfer and accelerate the charge extraction, but also enhance the charge utilization and improve the hydrogen reduction reaction dynamics. As a result, the composites exhibited a promoted hydrogen evolution rate of 9.5 mmol g −1 h −1 , which was about 3.8 times higher than that of pure ZIS. This work may extend the in-situ preparation strategy and motivate the intensive investigation of high-efficiency ZIS-based photocatalysts.

Photocatalytic technology plays a critical role in uranium extraction by converting soluble U(VI) into insoluble U(IV), underscoring the need to develop efficient catalysts for the photoreduction of U(VI) in aqueous environments. To address this challenge, researchers have developed core–shell MoO 3-X @ZnIn 2 S 4 (M@ZISn) photocatalysts, co-regulated through homometallic ion doping and heterojunction engineering, for U(VI) extraction. The M@ZIS 0.5 photocatalyst demonstrated outstanding performance, achieving a removal rate of 98.84 % and a removal capacity of 296.52 mg·g −1 within 90 min. Optical characterization revealed that its superior photocatalytic activity stems from three key factors: (1) Mo 5+ doping and heterojunction formation effectively suppressed the recombination of photogenerated electron-hole pairs, (2) the core–shell structure provided an efficient pathway for the transfer of photogenerated carriers, and (3) Density Functional Theory (DFT) calculations confirmed that homometallic ion doping and heterojunction engineering optimized the semiconductor’s bandgap structure and enhanced its performance. Notably, when applied to spiked natural water samples (from the Yellow River, Salt Lake, and seawater), the M@ZIS 0.5 catalyst maintained a high removal rate of 78.82 %, demonstrating its potential for practical applications in real-world water systems.

Due to the intrinsic chemically inert CO2 with the dissociation energy of C═O bond as high as 750 kJ mol–1, low efficiency and selectivity have become the most significant restraints for the practical application of photocatalytic CO2 reduction. Renewing the electronic structure of adsorbed CO2 on the catalyst surface through a rational catalyst design is crucial to achieving performance improvement. Herein, we prepared ZnIn2S4 and Cu-substituted ZnIn2S4 containing both Lewis acid and Lewis base sites as a model system for investigating the activation of CO2 by M–S chemical bonds (M represents a metal site). The Cu–S chemical bond can effectively activate CO2 as a vital electron channel and lower the Gibbs free energy for generating the essential intermediate *COOH. Besides, the Cu0.7-ZnIn2S4 sample displays 74.8% selectivity for reducing CO2 to CO with a rate of 47.2 μmol g–1 h–1, roughly 7.14 times that of ZnIn2S4.

The development of photocatalysts with non-noble metals and the effective separation of photoexcited carriers is a significant strategy for accelerating surface reaction kinetics and promoting water splitting to produce H 2 . Herein, an exquisite core-shell NiFe-LDH@ZnIn 2 S 4 heterojunction photocatalyst was constructed by in situ decoration of ultrathin ZnIn 2 S 4 nanosheets on the surface of the flower-like NiFe-LDH microsphere . The synthesized 3D hierarchical NiFe@ZIS-25 composite exhibits enhanced photocatalytic H 2 evolution activity, reaching 9.12 mmol·h -1 ·g -1 , which is 2.52-fold higher than pure ZnIn 2 S 4 . The significant improvement in H 2 evolution performance could be attributed to the hierarchical core-shell structure of the NiFe@ZIS-25 photocatalyst, which enhanced the light capture ability. In addition, the interfacial coupling effect of ZnIn 2 S 4 and NiFe-LDH is beneficial to the migration of carriers. More importantly, the construction of Z-scheme heterojunction efficiently promotes the fast translation of photogenerated carriers while preserving a stronger reduction potential to achieve H 2 evolution. This work elucidates a rational strategy to develop efficient photocatalysts with hierarchical core-shell structures for water splitting.

Heterojunction photocatalysts possess high efficiency in photogenerated electron-hole separation, which give significant advantages in the field of solar hydrogen production . Herein, a novel ZnIn 2 S 4 @S doped g-C 3 N 4 (ZIS@SCN) heterojunction with mesoporous structure was prepared for photocatalytic water splitting under visible light . Characterization showed that the element of S was successfully introduced into g-C 3 N 4 (CN) by replacing N to form C–S–C bonds and significantly enhanced the visible light absorption ability. The constructed heterojunction exhibited excellent photocatalytic hydrogen evolution under visible light. The best performance belonged to the sample of ZIS@100SCN. The corresponding H 2 production rate reached 9.3 mmol h −1 g −1 , which was 1.87-fold higher than that of the undoped one. More importantly, the heterojunction realized overall water splitting of H 2 and O 2 evolution simultaneously with good stability. The mechanism analysis indicted that introducing the element of S could regulate the band structure of CN and induce the charge transfer switching of a ZnIn 2 S 4 @g-C 3 N 4 (ZIS@CN) photocatalyst from Ⅰ-type to S-scheme, which promoted the efficient spatial charge separation and maintained the high redox ability of the ZIS and SCN. This work provides an insight in construction high performance S-scheme heterojunction for water splitting with a doping method.

A molecularly imprinted polymer/Bi 2 S 3 /ZnIn 2 S 4 /ITO sensor was fabricated and used for the photoelectrochemical detection of rutin. The Bi 2 S 3 /ZnIn 2 S 4 composite was synthesized by solvothermal method and it displayed good photoelectrochemical property because of the matched energy levels of Bi 2 S 3 and ZnIn 2 S 4 . In addition, ZnIn 2 S 4 could improve the stability of the composite and avoid photocorrosion. The photocurrent signal of the Bi 2 S 3 /ZnIn 2 S 4 composite was much larger than that of Bi 2 S 3 and ZnIn 2 S 4 under visible-light irradiation. Moreover, rutin imprinted chitosan was prepared by mixing rutin and chitosan solutions, followed by simple cross-linking reaction with glutaraldehyde at room temperature. The molecularly imprinted material was combined with Bi 2 S 3 /ZnIn 2 S 4 /ITO to construct photoelectrochemical sensor, and the resulting sensor showed a low detection limit (i.e. 0.003 μM) and a wide detection range (i.e. 0.01–100.0 μM) for rutin. It also displayed high stability and selectivity. The sensor could be used for the detection of rutin in real samples.

Construction of hierarchical architecture with suitable band alignment for graphitic carbon nitride (g-C 3 N 4 ) played a pivotal role in enhancing the efficiency of photocatalysts. In this study, a novel attapulgite-intercalated g-C 3 N 4 /ZnIn 2 S 4 nanocomposite material (ZIS/CN/ATP, abbreviated as ZCA) was successfully synthesized using the freeze-drying technique, thermal polymerization, and a simple low-temperature hydrothermal method. Attapulgite (ATP) was intercalated into g-C 3 N 4 to effectively regulate its interlayer structure. The results reveal a substantial enlargement of its internal space, thereby facilitating the provision of additional active sites for improved dispersibility of ZnIn 2 S 4 . Notably, the optimized photocatalyst, comprising a mass ratio of ATP, g-C 3 N 4 , and ZnIn 2 S 4 at 1:1:2.5 respectively, achieves an outstanding hydrogen evolution rate of 3906.15 μmol g −1 h −1 , without the need for a Pt co-catalyst. This rate surpasses that of pristine g-C 3 N 4 by a factor of 475 and ZnIn 2 S 4 by a factor of 5, representing a significant improvement in performance. This significant enhancement can be primarily attributed to the higher specific surface area, richer active sites, broadened light response range, and efficient interfacial charge transfer channels of the ZCA composite photocatalyst. Furthermore, the Z-scheme photocatalytic mechanism for the sandwich-like layered structure heterojunction was thoroughly investigated using diverse characterization techniques. This work offers new insights for enhancing photocatalytic performance through the expanded utilization of natural minerals, paving the way for future advancements in this field.

Semiconductor photocatalytic hydrogen evolution (PHE) has emerged as a feasible solution to address the problem of energy shortage. Hydrogen energy can thus be developed by creating a photocatalyst with a high activity for producing hydrogen and an effective charge transfer route. This study describes the preparation of innovative hierarchical ZnMn2O4@ZnIn2S4 (ZMOZ) ball-in-ball hollow microspheres as photocatalysts using a straightforward solvothermal technique. Remarkably, the PHE rate of the 10% ZMOZ can reach 11.12 mmol h–1 g–1, it roughly 4.9 greater than pure ZnIn2S4 (ZIS). Aside from the benefits of building heterojunctions, the regulation of morphology such as hollow structures that can provide more exposed active sites and enhance the light-absorption capability by internal multilight scattering. Through the use of density functional theory calculations (DFT), X-ray photoelectron spectroscopy (XPS), photoluminescence (PL) spectra as well as time-resolved PL (TRPL) spectroscopy also demonstrate that the charge separation efficiency in the composite was notably improved. This work offered a cost-effective and environmentally friendly method for utilizing visible light to construct an effective PHE.

To improve the photocatalytic performance of Mn 0.6 Zn 0.4 Fe 2 O 4 (MZFO) and ZnIn 2 S 4 (ZIS) for organic pollutants, the p-n MZFO@ZIS heterojunctions with different weight percentage (10 ~ 40%) of MZFO are constructed from spent batteries and added indium ion via a green bioleaching and hydrothermal method. Structural, optical, and photocatalytic properties for the heterojunctions are investigated systematically by XRD, FT-IR, SEM–EDX, TEM, BET, VB-XPS, UV–vis DRS, PL, etc. The results confirm that p–n junction significantly improves the visible light adsorption and the separation efficiency of photogenerated carriers. Specifically, MZFO-25%@ZIS shows the highest photodegradation performance toward Congo red (CR), and its reactive kinetic constant is about 9.6, 7.8, and 7.0 times higher than that of P25 TiO 2 , MZFO, and ZIS, respectively, and MZFO-25%@ZIS still possesses a high reusability and simple magnetic separation after 5 cycles of reuse. The radical trapping experiments and electronic paramagnetic resonance (EPR) tests show that · O 2 − , · OH, and h + are the most important active substance for degrading CR. The pathways for the CR degradation are further proposed based on the intermediate analysis. DFT + U calculations confirm that the high charge density of Zn–O, Fe–O, and Zn–S bonds in the MZFO and ZIS molecules provides the electrons for the sufficient production of free radicals. This work also provides a novel high value-added strategy for the green utilization of spent batteries.

The advancement of highly effective heterojunction photocatalysts with improved charge separation and transfer has become a crucial scientific perspective for utilizing solar energy. In this study, we developed the S-scheme heterostructure by depositing N-doped CeO 2-δ (NC) nanoparticles onto two-dimensional ZnIn 2 S 4 (ZIS) nanosheets via hydrolysis strategy for significantly enhanced photocatalytic hydrogen evolution reaction. The optimal H 2 generation rate of ∼ 798 μmol g –1 h –1 was achieved for NC-3@ZIS under solar light irradiation, which is about 18 and 2 times higher than those of pristine CeO 2 (∼44 μmol g –1 h –1 ) and ZIS (∼358 μmol g –1 h –1 ), respectively. The photogenerated electrons from NC interact with the photogenerated holes of ZIS driven by an internal electric field, confirmed by In-situ KPFM, DFT calculation, and XPS results. According to EPR and photoelectrochemical measurements, NC-3@ZIS composite shows dramatically high separation efficiency of photogenerated charge carriers. This study provides a new approach for developing non-noble metal S-scheme heterojunctions with enhanced photocatalytic hydrogen evolution.

Nowadays, aflatoxin B1 (AFB1) contamination is considered as one of the most common food safety issues for humans and animals. As one of the most advanced oxidation techniques, photocatalytic degradation can break down organic contaminants into nontoxic and harmless materials efficiently. In this paper, we explored the degradation efficiency of AFB1 by ZnIn2S4. To promote the photocatalytic degradation efficiency of AFB1, ZnIn2S4 was coupled with MIL-125(Ti) and then doped with La [this hybrid is denoted as La-ZnIn2S4/MIL-125(Ti)] to effectively convert it via photocatalytic generation of superoxide radicals (˙O2− and ˙OH) and achieve much enhanced photocatalytic performance, which is demonstrated by degrading 97.6% of AFB1. According to the transient photocurrent responses, the doping of La and coupling with MIL-125(Ti) can highly improve the efficient separation of the photoinduced electron–hole pairs on ZnIn2S4, leading to the effective conversion of OH− and O2 into ˙O2− and ˙OH, respectively, during the photodegradation process. This strategy of coupling with MOFs and doping with rare earth elements provides a facile and efficient method for degrading food pollutants produced by aflatoxins.

Hierarchical structure design and use of cocatalyst are effective strategies to improve the photocatalytic performance of semiconductor catalysts. Herein, 0D NiSe 2 nanoparticles decorated 2D ZnIn 2 S 4 ultrathin nanosheet-assembled microflowers using a facile solvothermal approach are synthesized. The as-obtained NiSe 2 /ZnIn 2 S 4 nanocomposites exhibit enhanced visible-light photocatalytic H 2 -evolution activity of 1487 µ mol (g h) –1 , three times higher than that of pure ZnIn 2 S 4 . The hierarchical structure of ZnIn 2 S 4 microflowers exposes more surface-active sites and enhances light harvesting. Meanwhile, the formation of heterojunctions between ZnIn 2 S 4 nanosheets and NiSe 2 nanoparticles creates a space-charge separation region that facilitates the transfer and separation of photoinduced electrons and holes, resulting in improved photocatalytic H 2 production. This work provides a promising strategy for designing and constructing 0D/2D heterojunctions for efficient solar-driven energy conversion.
