The extensively explored unary and binary 2D layered materials (2DLMs) based photodetectors suffer from deficiencies of either poor stability, or indistinctive photoswitching, or poor scalability, or low durability to high-temperature environment. Herein, a two-step scenario, pulsed laser deposition (PLD) followed by post-deposition annealing, is developed to produce centimeter-scale 2D ZnIn 2 S 4 (ZIS) nanofilms. Transport characterizations indicate that the as-fabricated ZIS photodetectors manifest outstanding photosensitivity with an on/off switching ratio beyond 1000 upon 405 nm illumination. Beyond this, it is revealed that the photoresponse of the ZIS photodetectors increases with increasing channel thickness, where a responsivity of 1.4 A W −1 , an external quantum efficiency of 430% and a detectivity of 9.8 × 10 9 Jones (1 Jones = 1 cm Hz 1/2 W –1 ) are demonstrated with a pulse number of 10 000. In addition, these devices without encapsulation maintain stable within 1900 photoswitching cycles and over a one-month storage in air. Furthermore, robust photoswitching is demonstrated under an operating temperature up to 150 °C. In summary, all these findings establish that PLD provides a powerful route to produce large-scale multielement 2DLMs and the PLD-derived ZIS photodetectors hold grand prospect for photoelectric technologies in specific high-temperature environments (e.g., the lunar exploration program).

Integrating selective organic synthesis with hydrogen (H 2 ) evolution in one photocatalytic redox reaction system sheds light on the underlying approach for concurrent employment of photogenerated electrons and holes towards efficient production of solar fuels and chemicals. In this work, a facile one-pot oil bath method has been proposed to fabricate a noble metal-free ultrathin Ni-doped ZnIn 2 S 4 (ZIS/Ni) composite nanosheet for effective solar-driven selective dehydrocoupling of benzyl alcohol into value-added C–C coupled hydrobenzoin and H 2 fuel, which exhibits higher performance than pure ZIS nanosheet. The remarkably improved photoredox activity of ZIS/Ni is mainly attributed to the optimized electron structure featuring narrower band gap and suitable energy band position, which facilitates the ability of light harvesting and photoexcited charge carrier separation and transfer. Furthermore, it has been demonstrated that it is feasible to employ ZIS/Ni for various aromatic alcohols dehydrocoupling to the corresponding C–C coupled products. It is expected that this work can stimulate further interest on the establishment of innovative photocatalytic redox platform coupling clean solar fuels synthesis and selective organic conversion in a sustainable manner.

Integration of photothermal materials and photocatalysts can effectively improve photocatalytic hydrogen production. However, the synergistic mechanism of photothermal effect and heterojunction still need to be deeply investigated. Herein, Co 3 O 4 @ZnIn 2 S 4 (ZIS) core–shell heterojunction was constructed as a photothermal/ photocatalytic integrated system for photocatalytic hydrogen production. The photothermal effect induced by Co 3 O 4 boosts the surface reaction kinetic of hydrogen evolution with an apparent activation energy decrease from 42.0 kJ⋅mol −1 to 33.5 kJ⋅mol −1 . The photothermal effect also increases the charge concentrations of Co 3 O 4 @ZIS, which ameliorates the conductivity of Co 3 O 4 @ZIS and thus benefits to charge transfer. In addition, a p-n junction forms between Co 3 O 4 and ZIS and provides a built-in electric field to enhance charge separate and prolong charge life time. Benefiting from the synergy of photothermal effect and heterojunction, the photocatalytic performance of Co 3 O 4 @ZIS is significantly improved with a highest hydrogen evolution rate of 4515 μmol⋅g −1 ⋅h −1 , which is about 3.5 times higher than that of pure ZIS. This work offers a full perspective to understand the photothermal/photocatalytic integrated conception for solar hydrogen production.

The increasing consumption of antibiotics and their subsequent release to wastewater or groundwater and ultimately to the water supply (or drinking water) has great concerns. This paper presents a visible light (VL) activated ferrate(VI) (Fe VI O 4 2- , Fe(VI)) system to degrade the selected antibiotic, trimethoprim (TMP), efficiently. An oxygen doped ZnIn 2 S 4 nanosheet (O-ZIS) coupled with a black phosphorus (BP) heterostructure (O-ZIS/BP), is fabricated by a simple electrostatic self-assembly method. The O-ZIS/BP photocatalyst is comprehensively characterized by surface and analytical techniques, which show superior separation efficiency of the photoinduced charge carriers in the heterostructure. A VL-O-ZIS/BP-Fe(VI) system achieves more than 80% removal in 1.0 min and complete removal of TMP in 3.0 min. Comparatively, only ⁓7% and ⁓24% of TMP are degraded by O-ZIS/BP and Fe(VI) in 1.0 min, respectively. The degradation experiments using probe molecules of reactive species and electron paramagnetic resonance (EPR) measurements reveal involvement of superoxide (O 2 -• ), hydroxyl radical ( • OH), and iron(V)/iron (IV) (Fe V /Fe IV ) species in the mechanism of TMP degradation. Oxidized products of TMP are identified and reaction pathways are given. Theoretical calculations predict the initial attack on the TMP molecule by the reactive species in the VL-O-ZIS/BP-Fe(VI) system. The activation of Fe(VI) by VL-heterostructure photocatalysts accelerates the degradation of antibiotics, demonstrating its potential for water depollution.

Efficient photocatalysts with visible light irradiation have a bright future in practical environmental remediation. ZnIn 2 S 4 is a promising environmentally friendly visible-light photocatalyst, due to its appropriate narrow band gap and excellent chemical stability. In this research, the RP/ZnIn 2 S 4 composites with flower spheroidal morphology were synthesized by loading RP onto the surface of ZnIn 2 S 4 via a one-pot hydrothermal process. The experimental results show that the tetracycline (TC) degradation efficiency of RP(1 wt%)/ZnIn 2 S 4 was up to 85.1 %, compared with pure RP, ZnIn 2 S 4 , and other series of RP/ZnIn 2 S 4 composites. The optimal degradation conditions were as following: 1 wt% RP modification amount, 30 mg catalyst amount, 30 mg/L initial TC solution concentration, and the initial reaction pH of 7. At the same time, good repeatability and stability of RP(1 wt%)/ZnIn 2 S 4 toward TC removal confirm its potential value for practical applications. In addition, the degradation efficiency of RP(1 wt%)/ZnIn 2 S 4 for rifamycin and ofloxacin under the similar conditions was 80.2 % and 65.3 %, respectively, indicating the universal application of RP/ZnIn 2 S 4 for degradation of different antibiotic pollutants. The possible photocatalytic mechanism was proposed based on the trapping experiment and ESR test. The RP(1 wt%)/ZnIn 2 S 4 composite photocatalytic materials with high efficiency and stability are expected to contribute to the exploration of the environmental protection field.

Developing novel photocatalysts with an intimate interface and sufficient contact is significant for the separation and migration of photogenerated carriers. In this work, a novel Co@NC/ZnIn2S4 heterojunction with a strong Co–S chemical bond was formed at the interface between Co@NC and ZnIn2S4, which accelerated charge separation. Meanwhile, the recombination of the electron–hole pairs was further restricted by the Co@NC/ZnIn2S4 Schottky junction. The Co@NC (5 wt%)/ZnIn2S4 composite exhibited an H2 evolution rate of 33.3 μmol h−1, which is 6.1 times higher than that of the pristine ZnIn2S4, and Co@NC/ZnIn2S4 showed excellent stability in the photocatalytic water splitting reaction. Its apparent quantum yield reached 38% at 420 nm. Furthermore, the Kelvin probe test results showed that the interfacial electric field formed as the driving force for interface charge transfer was oriented from Co@NC to ZnIn2S4. In addition, the Co–S bond as a high-speed channel facilitated the interfacial electron transfer. This work reveals that in situ formed chemical bonds will pave the way for designing high-efficiency heterojunction photocatalysts.

A new, photoelectrochemical immunosensor was proposed on the basis of the La-CdS/3D ZnIn 2 S 4 /Au@ZnO sensitization structure for detection of aminoterminal pro-brain natriuretic peptides (NT-proBNP). The Au@ZnO-modified electrode was first assembled with 3D ZnIn 2 S 4 , and then further deposited with lanthanum doped cadmium sulfide (La-CdS) via successive ionic layer adsorption and reaction strategy. The Au@ZnO has excellent photoelectric activity and electrical conductivity . The ZnIn 2 S 4 with 3D architectures not only exhibit high photocurrent intensity under visible-light irradiation but also have large surface for the La-CdS deposition. Meanwhile, the La-CdS doped structure could depress the charge recombination, which effectively promotes separation of the generated electron-hole (e - /h + ) pairs and consequently enhances the photocurrent conversion efficiency. The polydopamine (PDA) was used not only as a cross-linker reagent for the immobilization of the anti-NT-proBNP but also as an electron donor for promoting the photo-generated e - /h + separation of the semiconductors. Under optimal conditions, the well-designed photoelectrochemical immunoassay exhibited a low detection limit of 0.32 pg mL −1 and a wide linear range from 0.8 pg mL −1 to 45 ng mL −1 for target NT-proBNP detection. Meanwhile, it also presented good reproducibility, specificity, and stability and might open a new promising strategy for the detection of other important tumor markers.

A novel three-dimensional (3D) ZnIn 2 S 4 /WO 3 (ZIS/WO 3 ) photocatalyst is prepared via a simple hydrothermal method and used as photoanode material in constructing photoelectrochemical (PEC) immunosensor of prostate specific antigen (PSA). The photocatalyst presents high activity, and its photocurrent intensity is up to 23 and 7 times of WO 3 and ZnIn 2 S 4 (ZIS) respectively, under 430 nm light illumination. The improved PEC behavior is due to the sensitization and 3D structure of ZIS and the formation of Z-scheme heterojunction between ZIS and WO 3 , which greatly enhance light harvesting, promote the spatial separation of interfacial charges and prolong the lifetime of photogenerated electrons. At the same time, the high oxidation capacity of valence band holes of WO 3 is retained. A label-free PEC immunosensor is fabricated by using the photocatalyst, and it shows good performance for PSA detection. The linear response range is 0.01–500 ng/mL, and the detection limit is low to 5 pg/mL. Moreover, the PEC immunosensor afforded high stability, specificity and reproducibility. Therefore, it possesses great application potential in biological/clinical analysis.

Efficient heterojunction photocatalysts with spatial separation of photogenerated carriers are crucial to photocatalysis. Herein, the unique carbonized polymer dots/ZnIn 2 S 4 (CPDs/ZIS) Z-scheme heterojunction is designed to realize efficient spatial directional separation of photogenerated carriers. The CPDs broaden the light absorption range of ZIS and lengthen the lifetime of photogenerated charges. As the enrichment center of photogenerated electrons and active site of activated oxygen, CPDs generate more superoxide radicals to facilitate mineralization of organic pollutants by means of confined catalysis. The Z-scheme migration mechanism of photogenerated carriers in the CPDs/ZIS composite preserves the original valence band potential of ZIS and retains more holes for oxidation. Compared to the pristine ZIS, the CPDs/ZIS composite delivers enhanced photocatalytic performance in pollutant degradation. Electron spin resonance spectroscopy, free radical capture experiments, and liquid chromatography/mass spectrometry are performed to elucidate the photocatalytic mechanism of CPDs/ZIS.

In this study, a novel g-C3N4-based ternary heterojunction was rationally designed and constructed by the in situ growth of ZnIn2S4 nanosheets and CdS nanoparticles onto the g-C3N4 nanosheets using a facile two-step oil-bath method. Through optimizing the proportion of ZnIn2S4 and CdS component, g-C3N4 nanosheets coupled with ZnIn2S4 nanosheets and CdS nanoparticles (denoted as CdS/ZnIn2S4/g-C3N4) exhibited obviously higher photocatalytic properties for RhB removal than the single-component and dual-component systems. Among the as-obtained ternary photocatalysts, it was found that the ternary CdS/ZnIn2S4/g-C3N4-0.2 photocatalyst displayed the optimum photocatalytic property (96%) within a short time (30 min), which was almost 27.42 and 1.17 times higher than that of pure g-C3N4 and binary ZnIn2S4/g-C3N4-0.7 composite. The excellent activity of the ternary CdS/ZnIn2S4/g-C3N4 heterostructure is assigned to the synergetic effects of CdS nanoparticles, ZnIn2S4 nanosheets and g-C3N4 nanosheets, which not only broaden the visible-light absorption range, but also improve the charge mobility and separation rate, thus boosting the visible-light-driven photocatalytic property of g-C3N4.

The research of waste recycling and clean energy are the key to sustainable development. To simultaneously accomplish the waste recycling and clean energy generation, carbon fibers (Fiber) prepared from the spent cigarette filters are utilized to promote the photocatalytic hydrogen evolution efficiency of a heterojunction photocatalyst. The spiral ladder morphology of Fiber supplies abundant loading sites for the ZnIn 2 S 4 /g-C3N 4 photocatalysts, allowing efficient charge separation. Detailed chemical and optical features of the samples are subsequently demonstrated by a combination of scanning electron microscopy, X-ray diffraction, Fourier transform infrared tests. X-ray photoelectron spectrum results reveal that a strong internal electric field was formed between Fiber and ZnIn 2 S 4 /g-C 3 N 4 , allowing sufficient driving force to extract the photo-generated electrons from the heterojunction photocatalyst. Gas chromatography monitors a ca . 37 % enhancement for H 2 evolution (322.41 μmol·g −1 ·h −1 ) compared with control group. This work suggests an attempt to exploit general wastes for promoting photocatalytic hydrogen evolution.

Hydrogen peroxide (H 2 O 2 ) is an important green oxidant for environmental remediation. It is a sustainable strategy to realize solar-driven in- situ H 2 O 2 production for timely using via cascade reactions to sterilization or remove organic pollutants etc. However, how to improve the H 2 O 2 production and consumption abilities of catalysts are the two main challenges. Here we report a superior carbon-related ZnIn 2 S 4 /g-C 3 N 4 catalyst with excellent H 2 O 2 generation and consumption capabilities for efficient sterilization under visible light irradiation. The 2D/2D heterojunction of ZnIn 2 S 4 /g-C 3 N 4 with rapid carrier separation and transfer efficiency exhibits a remarkable H 2 O 2 yield of 4.27 mmol g −1 , which is much higher than that of current catalysts. The in- situ produced H 2 O 2 can be quickly activated to strong oxidizing hydroxyl radicals for sterilization, in which the Escherichia coli ( E. coli ) are fully cleared only within 25 min and 98% of Staphylococcus aureus ( S. aureus ) are killed out after 60 min irradiation. The prepared photocatalysts realize the rapid production and consumption of H 2 O 2 , and this work provides an effect green strategy for sterilization via the in- situ generated H 2 O 2 .
