The utilization of heterojunction photocatalysts in photocatalytic CO 2 conversion has attracted significant attention. Nevertheless, the interface structure between the two components in the heterojunction material essentially decides the carrier separation efficiency and the performance of photocatalytic CO 2 reduction. The development of semiconductor heterojunctions with suitable materials and intimate interfacial contact is paramount. In this study, SnIn 4 S 8 /Co 3 O 4 heterostructures have been successfully fabricated by a facile hydrothermal synthesis method. The experimental results demonstrated that the established internal electric field effectively suppressed the recombination of photogenerated carriers and accelerated charge transfer kinetics. Meanwhile, the increased specific surface area endows SnIn 4 S 8 /Co 3 O 4 heterostructures with an improved CO 2 adsorption ability, ultimately achieving a significant improvement in photocatalytic activity. The highest formation rate of CO and CH 4 reaches 38.20 and 3.60 μmol g −1 h −1 . The design strategy reveals the potential of establishing intimate interfacial contacts as an extremely efficient catalyst for photocatalytic CO 2 reduction, facilitating effective charge separation. This work provides distinctive thoughts for the development of advanced catalytic material design for CO 2 conversion and other photocatalytic applications.

Hierarchically porous reduced graphene oxide/SnIn4S8(RGO/SnIn4S8) composites with visible-light response and strong mineralization ability were first successfully prepared by a facile low-temperature co-precipitation method, and were characterized by X ray diffraction (XRD), scanning electron microscope (SEM), Brunauer-Emmet-Teller (BET), UV-Visible spectrophotometer (UV-Vis), Raman spectra and Photoluminescence (PL) techniques. RGO/SnIn4S8composite exhibits strong absorption in UV and visible-light range. The optimized 5% RGO/SnIn4S8possesses the optimal photocatalytic degradation efficiency and the best mineralization performance with complete degradation of Rhodamine B (RhB) within 70 min and 73.17% mineralization yield within 160 min under visible-light irradiation, which is much higher than that of pure SnIn4S8. The main reactive species, which play crucial roles in the degradation and mineralization of RhB, follow the order of h+> ·O2−> ·OH. The intermediate products of RhB degradation were analyzed by using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS), and the possible degradation pathways and mechanism were proposed. Moreover, 5% RGO/SnIn4S8exhibits excellent reusability and stability without an obvious decrease in photocatalytic activity after four consecutive photocatalytic degradation-regeneration experiments.Keywords:SnIn4S8;reduced graphene oxide;composite;visible light;mineralization

Hierarchical network-like graphitic carbon nitride/SnIn 4 S 8 (g-C 3 N 4 /SnIn 4 S 8 ) composites were prepared through a facile low-temperature co-precipitation method. The g-C 3 N 4 /SnIn 4 S 8 composite showed enhanced visible-light absorption. The band gap energies of g-C 3 N 4 , pure SnIn 4 S 8 , and 15 % g-C 3 N 4 /SnIn 4 S 8 are 2.58, 1.8, and 1.68 eV, respectively. The photocurrent and photocatalytic activity of the g-C 3 N 4 /SnIn 4 S 8 composites firstly increased and then decreased with increasing g-C 3 N 4 content, and it was found that the optimal 15 % g-C 3 N 4 /SnIn 4 S 8 exhibited the highest photocurrent intensity and best photocatalytic performance with complete degradation of MO within 80 min under visible-light irradiation, which is much higher than that of pure SnIn 4 S 8 . The effect of main reactive species on the MO degradation follows the order of h + > • O 2
− > • OH, and the possible degradation mechanism was proposed. Moreover, 15 % g-C 3 N 4 /SnIn 4 S 8 exhibits excellent reusability and stability without an obvious decrease of photocatalytic activity after four consecutive photocatalytic degradation–regeneration cycles.

A series of Au NPs decorated hierarchical In 2 O 3 /SnIn 4 S 8 microcubes were prepared by in-situ growing SnIn 4 S 8 nanosheets on the surface of In 2 O 3 microcubes and followed by reducing Au NPs on the surface of the hierarchical composite. The gas sensing performance of the sensors based on the as-prepared materials were systematically assessed. And the results showed that coverage of SnIn 4 S 8 and introduction of appropriate amount of Au NPs improved the gas sensing response of In 2 O 3 toward NO 2 at room temperature (RT). In particular, the sensor fabricated with 3 wt% Au NPs decorated In 2 O 3 /SnIn 4 S 8 exhibited excellent selectivity (S NO2 /S other > 12.6), high response (155.65–7 ppm NO 2 ), low theoretical limit of detection (LOD, 21.43 ppb), fast response/recovery time (132/191 s), good anti-interference performance, as well as repeatability and stability. The outstanding sensing performance at RT might be associated with a synergistic effect of heterostructures and the spillover effect of Au NPs, which could enlarge the electron depletion layer and promote the adsorption and dissociation of oxygen and nitrogen dioxide molecules.

Multinary metal sulfides are receiving more and more attention in the field of photocatalysis due to their excellent photoelectronic properties, but they usually suffer from the low photogenerated carrier separation efficiency and poor photostability. In this work, a dual multinary metal sulfides composite system is developed to address these issues. A unique multi-hierarchical Z-scheme heterojunction is successfully constructed by in - situ growth of branched SnIn 4 S 8 nanosheets on nanopetals of flower-like ZnIn 2 S 4 . The prepared optimal composite photocatalyst displays significantly enhanced visible-light photocatalytic activity with H 2 evolution rate of 2.988 mmol g −1 h −1 , Cr(VI) reduction rate constant of 0.094 min −1 and dye degradation rate constant of 0.152 min −1 , which are 4.5, 9.4 and 19 times of bare SnIn 4 S 8 , and 2.9, 4.3 and 3.5 times of bare ZnIn 2 S 4 , respectively. The improved photocatalytic performance is primarily attributed to the abundant porous channels of the novel hierarchical flower-shaped architecture and the formation of the direct Z-scheme heterojunction, guaranteeing the richer active sites, better light harvesting, stronger redox capability, and more efficient charge transfer. This work demonstrates the promising applications of the SnIn 4 S 8 /ZnIn 2 S 4 hybrid in energy and environmental photocatalysis fields, and should be instructive for the design and modification of multinary sulfide photocatalysts.

Octahedral CdS/SnIn 4 S 8 nano-heterojunctions were fabricated by a facile and simple one-step in situ hydrothermal method, and the molar ratio of CdS to SnIn 4 S 8 was optimized. The optimal (0.5:1)CdS/SnIn 4 S 8 heterojunctions exhibit the highest visible-light photocatalytic activity with 97.1% degradation efficiency of 2-nitrophenol in 120 min, which is much higher than those of individual CdS and SnIn 4 S 8 . The enhanced photocatalytic performance could be attributed to the effective separation and transfer of photogenerated charges originating from the well-matched band gap structures. Of special significance is that (0.5:1)CdS/SnIn 4 S 8 can effectively mineralize 2-nitrophenol and real pharmaceutical wastewater. Moreover, CdS/SnIn 4 S 8 nano-heterojunctions show excellent reusability in five cycles due to the stable surface composition and chemical valence state.

Although ternary chalcogenide compounds are effective photocatalysts for degrading organic pollutants under visible-light irradiation, their photocatalytic activity and stability are still low and far from practical application. In this study, two-dimensional AgInS 2 /SnIn 4 S 8 nanosheet heterojunctions were fabricated by one-step hydrothermal method. AgInS 2 /SnIn 4 S 8 nanosheet heterojunctions have strong visible-light absorption and narrow band gap of 2.27–2.35 eV, and exhibit excellent visible-light photocatalytic activity in the degradation of 2-nitrophenol (2NP) and tetracycline hydrochloride (TC·HCl) compared with pure AgInS 2 and pure SnIn 4 S 8 , which is attributed to the efficient separation of photogenerated electrons and holes. The practical application of AgInS 2 /SnIn 4 S 8 nanosheet heterojunctions was further studied. 20 mg AgInS 2 /SnIn 4 S 8 heterojunctions can effectively treat 100 mL real pharmaceutical industry wastewater in presence of H 2 O 2 with 65.98% mineralization efficiency, and the chemical oxygen demand (COD) of pharmaceutical industry wastewater decreases to 153 mg/L, which meets the discharge standards of industrial effluent. Moreover, AgInS 2 /SnIn 4 S 8 heterojunctions can maintain long-term activity without obvious inactivation after five consecutive catalytic cycles without using regeneration means.

Urchin-like SnIn 4 S 8 (donated as SIS) photocatalysts were successfully prepared by a rapid and facile microwave assisted synthesis method. The surface morphology, the composition and structure together with the optical performance of SIS prepared at different reaction time were investigated. The results indicated SIS synthesized with 20 min (donated as SIS-20, same below) exhibited higher photocatalytic activity under visible light towards the degradation of RhodamineB than that of SIS-10, SIS-30 as well as SIS synthesized by solvothermal method, larger specific surface areas and lower band gap energy were found to contribute photocatalytic efficiency. Surprisingly, SIS-20 possessed durable stability and recyclability.

As an oil-soluble antioxidant, tert -butylhydroquinone (TBHQ) is widely used in edible oils, so accurate control of its content is significant for food safety. Here, a CdIn 2 S 4 /SnIn 4 S 8 S-scheme heterojunction structure was constructed by in-situ growth of smooth flower-like CdIn 2 S 4 on rough three-dimensional SnIn 4 S 8 microspheres via a one-pot co-precipitation technique. Subsequently, TBHQ was combined with CdIn 2 S 4 /SnIn 4 S 8 /GCE, and the photocurrent signal was significantly increased, which could be detected in the concentration range from 0.02 to 150 μM, with the limit of detection as low as 2 nM. The reaction mechanism of CdIn 2 S 4 /SnIn 4 S 8 composites was verified by using density functional theory calculations. Meanwhile, the reason for the outstanding detection of TBHQ was investigated by exploring the electrostatic potential and the related redox potential. In addition, the sensor was demonstrated to have excellent recoveries by comparing UV–Vis spectrophotometry for the detection of TBHQ in peanut oil, canola oil, blended oil, and soybean oil.

Tert -Butylhydroquinone (TBHQ) is a phenolic antioxidant commonly found in edible oils. However, excessive amounts of TBHQ can adversely affect food quality due to its toxic and mutagenic effects, which may cause human injury and present carcinogenic risks. Thus, there is an urgent need to develop a sensitive and accurate analytical method for the rapid detection of TBHQ. In this work, hierarchical flower-structured spherical SnIn 4 S 8 and pyramidal Bi 2 O 3 were combined to obtain the Z-scheme SnIn 4 S 8 /Bi 2 O 3 heterojunction. Under irradiation, the electron transport channel of this heterojunction facilitated the combination of electrons in the conduction band of Bi 2 O 3 with holes in the valence band of SnIn 4 S 8 , which decreased the recombination rate of photogenerated electrons and improved the photoelectric response. After the addition of TBHQ, the adsorption effect on the electrode surface and the oxidation reaction with holes in the valence band of Bi 2 O 3 further promoted the charge transfer and separation of photogenerated electrons and holes, which led to a rapid increase in the photocurrent to realize the detection of TBHQ in environmental and food samples. The increase in photocurrent has been linearly correlated with the logarithm of the concentration of TBHQ in the range of 1.00–500 μM with a limit of detection of 0.526 μM. Furthermore, the sensor showed excellent selectivity in the presence of a wide range of analogs. This study provides a novel scheme for the precise detection of TBHQ and the construction of high-performance photoelectrochemical Z-scheme heterojunctions.

Efficient separation of photogenerated charge carriers is vitally significant in the photocatalytic reaction process. In this work, a novel Zn 0.1 Cd 0.9 S/Snln 4 S 8 (ZCS/SIS) core-shell nanorods photocatalyst was prepared by a facile solvothermal method. The photocatalytic activity of the as-synthesized samples were evaluated by the degradation of Rhodamine B (RhB) and imidacloprid (IM) under visible light irradiation. Compared with the pristine ZCS and SIS, the core-shell composites displayed dramatically improved photocatalytic activity. The apparent rate constants of RhB and IM photodegradation over ZCS/SIS are 5.07 and 16.9 time higher than that of pure ZCS, respectively. In addition, the electrochemical measurements indicate that the charge carriers separation in ZCS/SIS core-shell composites is enhanced. The reason could be the formation of the core-shell ZCS/SIS heterojunction boosting the charge carriers separation and transfer. Besides, a possible photocatalytic mechanism was proposed.

Composite photocatalyst have garnered considerable attention in the field of environmental remediation. In this study, we synthesized a one-dimensional (1D) core/shell AgVO 3 @SnIn 4 S 8 (AS) heterojunction photocatalyst by in situ growing SnIn 4 S 8 nanosheets on AgVO 3 nanorods utilizing a straightforward solvothermal approach. The resultant AS composite demonstrates exceptional photocatalytic efficiency in both degrading methyl orange (MO) and reducing Cr(VI) pollutants. The optimized AS-0.1 heterostructure is particularly noteworthy, achieving almost complete MO degradation (99.7 %) within just 15 min and effectively reducing Cr(VI) 99.4 % within 75 min. The reaction rate constant k for MO degradation by the AS-0.1 sample is 0.3654 min⁻¹ , which is 8.2 times higher than that of SnIn₄S₈ (0.0446 min⁻¹) and 609 times greater than that of AgVO₃ (0.0006 min⁻¹). Similarly, the degradation constant k for Cr(VI) reduction by AS-0.1 is 0.0656 min⁻¹ , surpassing that of SnIn₄S₈ by 5.2 times (0.0127 min⁻¹) and AgVO₃ (0.0003 min⁻¹) by 218.7 times. This significant enhancement in photocatalytic activity is primarily attributed to the increased number of active sites and the efficient S-scheme charge transfer mechanism, which is facilitated by the built-in electric field within the AS heterostructure. The S-scheme mechanism facilitates the efficient migration of photogenerated charge, and endows photoexcited electrons and holes with high redox capacity, thereby accelerating the photocatalytic reactions. Furthermore, the recovered samples retain their photocatalytic degradation performance after five consecutive experimental cycles, suggesting their excellent durability. This study is expected to motivate the rational design and fabrication of efficient composite photocatalysts, offering innovative solutions to water pollution challenges.
