The development of low-cost and efficient metal sulfide photocatalysts through morphological and structural design is vital to the advancement of the hydrogen economy. However, metal sulfide semiconductor photocatalysts still suffer from low carrier separation and poor solar-to-hydrogen conversion efficiencies. Herein, two-dimensional ZnIn 2 S 4 nanosheets were grown on Zn 0.5 Cd 0.5 S hollow nanocages to construct Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 hollow nanocages for the first time. Novel hollow core–shell Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 /MoS 2 nanocages with Z-scheme heterojunction structures were obtained by incorporating MoS 2 nanosheet co-catalyst via the solvothermal method. The resulting Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 /MoS 2 exhibited unique structural and compositional advantages, leading to remarkable photocatalytic hydrogen evolution rates of up to 8.5 mmol·h −1 ·g −1 without the use of any precious metal co-catalysts. This rate was 10.6-fold and 7.1-fold higher compared to pure ZnIn 2 S 4 and Zn 0.5 Cd 0.5 S, respectively. Moreover, the optimized Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 /MoS 2 photocatalyst outperformed numerous reported ZnIn 2 S 4 -based photocatalysts and some ZnIn 2 S 4 -based photocatalysts based on precious metal co-catalysts. The exceptional photocatalytic performance of Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 /MoS 2 can be attributed to the Z-scheme heterojunction of core–shell structure that enhanced charge carrier separation and transport, as well as the co-catalytic action of MoS 2 . Overall, the proposed Zn 0.5 Cd 0.5 S@ZnIn 2 S 4 /MoS 2 with heterojunction structure is a promising candidate for the preparation of efficient photocatalysts for solar-to-hydrogen energy conversion.

Facing the requirement of modern industrial development, selective reduction of 4-nitroaniline (4-NA) into p-phenylenediamine (PPD) via a facile, economic and eco-friendly photocatalysis technique has attracted more and more attention in recent years. In this study, ZnIn 2 S 4 (ZIS) nanosheets grew in-situ on the surface of TiO 2 hollowspheres through a hydrothermal method and formed a direct Z-scheme heterojunction composite, which exhibited exceedingly better photocatalytic 4-NA reduction performance than bare ZIS and TiO 2 . Such enhancement was mainly attributed to the dissimilar dimensionalities, intimate contact, and matchable band edge positions between ZIS and TiO 2 semiconductors. Moreover, the substantial mechanism for the photocatalytic reaction in the ZIS/TiO 2 system was reasonably proposed. Inspired by recent applications of the Z-scheme heterostructured materials in solar energy conversion and artificial photosynthesis, this work would arouse an increasing interest in designing more Z-scheme photocatalyst systems with high efficiency and extensive applications.

A ZnIn2S4/CdS photocatalyst was synthesized based on an electrostatic interaction mechanism and was used to construct a photoelectrochemical (PEC) sensor for the highly sensitive and selective detection of dopamine (DA). As CdS and ZnIn2S4 possessed overlapping band potentials, they could form a heterojunction, which was favorable for charge separation and PEC conversion. Thus, the ZnIn2S4/CdS composite showed better PEC properties and higher photocatalytic activity than pure ZnIn2S4 and CdS. When it was used for DA sensing in a weak alkaline solution, DA turned to polydopamine and acted as an effective electron acceptor to make the anodic photocurrent decrease. Owing to adopting this detection strategy, the interference of coexistent reductive species (i.e., electron donor) was avoided effectively. Under the optimized conditions, the photocurrent change was linear to DA concentration in the range from 0.3 to 300 μM, and the detection limit was 0.1 μM. The ZnIn2S4/CdS/indium tin oxide sensor was applied for the indirect detection of DA in urine samples, and it presented a good performance.

At present, inefficient charge separation is considered to be one of the most important factors, limiting the photocatalytic hydrogen production. To solve this problem, herein, hierarchical Cu7S4/ZnIn2S4 decorated with black phosphorus quantum dots (BPQDs) was rationally designed and its photocatalytic hydrogen evolution was investigated under visible light. The structural characterization proved the wrapped morphology of ZnIn2S4 grown on the Cu7S4 nanocrystals and BPQDs were uniformly dispersed on the surface of ZnIn2S4. Moreover, the close hierarchical structure of Cu7S4 with ZnIn2S4 and carrier separation facilitator of BPQDs were synergistically beneficial for boosting charge separation and transfer. The hydrogen production results showed that the ternary BPQDs@10% Cu7S4/ZnIn2S4 yielded the highest H2 evolution rate of 885 μmol g−1 h−1, about 6.8 times higher than that of the pristine ZnIn2S4, indicating its promising application in hydrogen production. In addition, the possible working mechanism was deeply explored using photo-electrochemistry, and the results illustrated that the enhanced photocatalytic hydrogen evolution can be attributed to the efficient charge separation caused by the formation of the hierarchical interface structure and increased carrier transfer efficiency of BPQDs. This study demonstrates that the regulation of interfacial charge transfer can positively facilitate photocatalytic activity and the ternary BPQDs@10% Cu7S4/ZnIn2S4 can be employed as an efficient candidate for hydrogen production.

In this paper, the g-C 3 N 4 /ZnIn 2 S 4 composite was synthesized by a two-stage hydrothermal method. The microstructure, surface, and optical properties of the composite were thoroughly characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area analysis, and UV-Vis absorption spectroscopic analysis. The removal capacity of Cr(VI) was optimized by using ZnIn 2 S 4 loaded in the composite. Meanwhile, the optimal pH environment for the reduction of Cr(VI) was determined to be about pH 3, and the reduction efficiency could reach more than 99% within 60 min. Further, the results of UV-Vis absorption analysis indicated the high and wide range of light absorption by composite compared with pure g-C 3 N 4 . Therefore, the enhanced photocatalytic performance of the composite could be attributed to the well-matched energy band structure between g-C 3 N 4 and ZnIn 2 S 4 , which apparently promoted the effective separation and transfer of photogenerated carriers. In addition, the composite showed good stability in the visible light catalytic reaction, and the possible mechanism of the photocatalytic activity of Cr(VI) reduction by the composite was proposed.

Lanthanide oxides have potential advantages for photocatalytic hydrogen production . To systematically investigate the photocatalytic performance of lanthanide oxides on metal sulfides , a series of Ln x O y /ZnIn 2 S 4 (Ln x O y /ZIS) were synthesized by hydrothermal method . Comprehensive characterization demonstrated that Ln x O y synergistically improved the performance of ZnIn 2 S 4 by extending light absorption, reducing contact interface resistance and enhancing carrier separation. The photocatalytic hydrogen evolution (PHE) rates of the Ln x O y /ZIS photocatalysts were improved, which were 1.6–4.2 times higher than those of pure ZnIn 2 S 4 (198.0 μmol g −1 h −1 ). The PHE rates of Ln x O y /ZIS decreased with increasing lanthanide atomic number, and when the lanthanides contained variable valence ions, the PHE rates of Ln x O y /ZIS were superior to those of neighbouring lanthanides. The heterojunction formed by Ln x O y and ZnIn 2 S 4 effectively promoted carrier separation. Lanthanide ions with unoccupied 4 f orbital were more likely to accept electrons and served as a hydrogen adsorption site for further hydrogen reduction. Multivalent ions could also promote the migration of electrons and generate oxygen vacancies to inhibit the recombination of carriers. In conclusion, for ZnIn 2 S 4 , lanthanide oxides are promising candidates to improve the performance of PHE. This study provides guidance on the selection of appropriate lanthanide oxides for the construction of efficient sulphur-based heterojunction photocatalysts.

The development of sensitive breast cancer biomarker (CA 15-3) measurement techniques is of great significance for the early diagnosis and therapeutic monitoring of breast cancer worldwide. Herein, we have designed a split-type photoelectrochemical (PEC) immunoassay platform for the ultrasensitive determination of CA 15-3 using In2O3/ZnIn2S4 heterojunctions with high photovoltaic conversion performance as a photoactive substrate. Efficient photocurrent-responsive In2O3/ZnIn2S4 was formed by surface loading narrow-bandgap ZnIn2S4 on MOF-derived wide bandgap In2O3 nanomaterials. Subsequently, a sandwich immunoreaction was performed using an alkaline phosphatase (ALP)-labeled secondary antibody as a signaling indicator to produce large amounts of ascorbic acid by enzymatic biocatalysis. Since ascorbic acid is an excellent electron donor capable of promoting photogenerated electron separation in semiconductor materials, it enhances the anodic photocurrent of In2O3/ZnIn2S4-modified electrodes. Under the optimal catalyst loading and immunoreaction time, the In2O3/ZnIn2S4-based PEC immunoassay showed a good photocurrent response to CA 15-3 over a wide detection range from 1.0 mU mL−1 to 10 000 mU mL−1 with a limit of detection of 0.45 mU mL−1. Owing to the excellent photocurrent response of In2O3/ZnIn2S4 to ascorbic acid and the split-type immunoassay protocol, the constructed PEC immunosensing platform has the advantages of high precision, anti-interference, and acceptable accuracy, and the results are equivalent to those of commercial enzyme-linked immunosorbent assay (ELISA) kits.

Two dimensional (2D) photocatalytic materials are desirable to achieve synergistic charge transfer and segregation. Here, we have developed 2D ZnIn 2 S 4 nanosheet (3–4 nm) that generates more active sites for excellent photocatalytic activity. Further, we have fabricated ZnS quantum dots (QDs) and ZnS nanoparticles (NPs) embedded with ZnIn 2 S 4 nanosheet in the form of ZnS QDs/ZnIn 2 S 4 and ZnS NPs/ZnIn 2 S 4 heterostructures prepared via one step hydrothermal method. The optimal ZnS QDs/ZnIn 2 S 4 presents the hydrogen evolution rate (HER) of 4.5 mmol g −1 h −1 which was approximately 5 and 34 times higher than that of their counterparts as well as about 3 times more efficient than ZnS NPs/ZnIn 2 S 4 heterostructure. The apparent quantum efficiency (AQE) of 21.2% was observed at 350 nm. The work functions determined through Ultraviolet photoelectron spectroscopy (UPS) elaborate the charge transfer mechanism. In situ KPFM validated the surface potential difference between the ZnS QDs and ZnIn 2 S 4 interfaces estimated about 55 mV which was approximately 2 times higher than ZnS NPs/ZnIn 2 S 4 . Theoretical calculation confirms the significant reduction in Gibbs free energy about −0.6 eV. Electron paramagnetic resonance (EPR) spectra suggest the development of a novel S-scheme mechanism and provides a unique insight into the charge transfer, separation and the surface photovoltage of heterostructure photocatalysts.

A novel ternary heterojunction material In 2 O 3 /In 2 S 3 /ZnIn 2 S 4 was synthesized, and a photoelectrochemical sensor was fabricated for the non-invasive test of dopamine (DA) in sweat. In 2 O 3 multihollow microtubules were synthesized and then In 2 S 3 was formed on their surface to construct a type-I heterojunction between In 2 S 3 and In 2 O 3 . ZnIn 2 S 4 was further introduced to form a Z-scheme heterojunction between In 2 S 3 /ZnIn 2 S 4 . Under photoexcitation, the photogenerated holes of In 2 O 3 transferred to the valence band of In 2 S 3 , superimposed with the holes produced by In 2 S 3 , leads to a significantly higher photocatalytic oxidation capacity of In 2 O 3 /In 2 S 3 /ZnIn 2 S 4 ternary composites than that of In 2 O 3 /In 2 S 3 . The Z-scheme heterojunction accelerates the transfer of photogenerated electrons accumulated on the type-I heterojunction. In the presence of DA, it is rapidly oxidized into polydopamine (PDA) by In 2 O 3 /In 2 S 3 , and the benzoquinone groups of PDA compete for the photogenerated electrons to reduce the current in the external circuit, whereby DA determination is achieved. Owing to the combination of type-I and Z-scheme heterojunction, the sensor showed extremely high sensitivity, with a detection limit of 3.94 × 10 −12 mol/L. It is one of the most sensitive methods for DA detection reported and has been applied to the determination of DA in human sweat. Graphical Abstract

Major issues in photocatalysis include improving charge carrier separation efficiency at the interface of semiconductor photocatalysts and rationally developing efficient hierarchical heterostructures. Surface continuous growth deposition is used to make hollow Cu 2-x S nanoboxes, and then simple hydrothermal reaction is used to make core-shell Cu 2-x S@ZnIn 2 S 4 S-scheme heterojunctions. The photothermal and photocatalytic performance of Cu 2-x S@ZnIn 2 S 4 is improved. In an experimental hydrogen production test, the Cu 2-x S@ZnIn 2 S 4 photocatalyst produces 4653.43 µmol h −1 g −1 of hydrogen, which is 137.6 and 13.8 times higher than pure Cu 2-x S and ZnIn 2 S 4 , respectively. Furthermore, the photocatalyst exhibits a high tetracycline degradation efficiency in the water of up to 98.8%. For photocatalytic reactions, the hollow core-shell configuration gives a large specific surface area and more reactive sites. The photocatalytic response range is broadened, infrared light absorption enhanced, the photothermal effect is outstanding, and the photocatalytic process is promoted. Meanwhile, characterizations, degradation studies, active species trapping investigations, energy band structure analysis, and theoretical calculations all reveal that the S-scheme heterojunction can efficiently increase photogenerated carrier separation. This research opens up new possibilities for future S-scheme heterojunction catalyst design and development.

In this work, a novel flexible photoelectrochemical immunosensor is developed to determine cardiac troponin I (cTnI) in serum. The flower-like ZnIn2S4 nanospheres (ZIS), as signal amplification material, were successfully synthesized by a solvothermal method. The ZIS and Bi2Se3 were modified on the indium tin oxide- polyethylene terephthalate (ITO-PET) electrode, which effectively accelerates the electronic transition and improved the photocurrent conversion efficiency (signal on). However, the binding of antigen–antibody proteins blocks the electron transfer, resulting in a greatly reduced photocurrent (signal off). By adding the second antibody modified by CdSe quantum dots (CdSe QDs-Ab2), the photocurrent is increased (signal on). The constructed immunosensor has a linear range from 0.08 to 40 ng/mL with a detection limit of 0.026 ng/mL, which shows excellent selectivity, high sensitivity, and good stability. The photoelectrochemical immunosensor has broad application prospects for the clinical examination of myocardial infarction.

Photocatalytic reduction of CO2 to high value-added chemicals and fuels has received widespread attention. However, the higher thermodynamic stability of CO2 greatly limits its conversion efficiency. Frustrated Lewis pairs (FLPs) have been well-established to be very effective in CO2 activation. In this work, we prepared ZnIn2S4–AlOOH (ZIS–AlOOH) composites for visible-light-driven CO2 reduction. The Lewis basic OHv sites on the AlOOH surface (one H removed from OH) and an adjacent Lewis acidic unsaturated Al site (Al3+unsatur.) form the FLPs. The composite structure facilitated light absorption, CO2 adsorption activation, and separation of photogenerated carriers, thus improving the CO2 photoreduction activity (CO generation rate of 510.3 μmol g−1 h−1), and suppressing hydrogen evolution with the CO/H2 ratio increasing from 0.38 for ZnIn2S4 (ZIS) to 0.84 for ZIS–AlOOH. This work elucidates a rational strategy for the construction of efficient photocatalysts and provides insight into the mechanism of the photocatalytic CO2 reduction reaction.
