As an important byproduct during natural gas exploitation, green utilization of hydrogen sulfide (H 2 S) by photocatalysis has offered us the possibility for production of clean hydrogen (H 2 ) from H 2 S with low energy consumption. In this work, we have successfully introduced well-dispersed palladium sulfide (PdS) which is preferably loaded on In 2 S 3 of MnS/In 2 S 3 composite for improved photocatalytic hydrogen evolution from H 2 S aqueous solution. In contrast to binary MnS/In 2 S 3 , ternary MnS/In 2 S 3 /PdS has exhibited a remarkable and stable hydrogen production rate of 22.7 mmol g −1 h −1 with an apparent quantum yield of 34% at around 395 nm. A comprehensive structure characterization of the ternary composite including scanning transmission electron microscopy (STEM) and X-ray absorption spectroscopy (XAS) in combination with theoretical calculations confirm the good dispersion of PdS in the composite. Moreover, we discovered that PdS preferably interact with In 2 S 3 rather than MnS in the composite through Pd-S-In bond on the interface of the two. Photoluminescence (PL) spectra, surface photovoltage (SPV) spectra together with transient photocurrent and electrochemical impedance spectra (EIS) demonstrate the advantage of PdS for promoting the charge separation. This work sheds light on the positive effect on the enhanced activity of the corresponding system resulting from the preferable anchoring of highly dispersed PdS on In 2 S 3 in the composite by chemical Pd-S-In bond. Not only the high dispersion but also the preferable anchoring of the co-catalyst in the composite could hence inspire people for more rational designs of ternary composite in future.

Photocatalytic conversion of CO2 into fuel and value-added chemicals as a promising method has been applied recently to ease energy- or environment-related crises. Herein, we construct an In2S3@NH2-MIL-68(In)@In2S3 (denoted as SMS(In)) sandwich homologous heterojunction via a controllable in situ metal–organic frameworks (MOF) sulfuration process. The improved photoreduction activity mainly lies in the effective charge transfer and separation through a homogeneous interface, enhanced CO2 adsorption and mass transfer, and plentiful reactive sites. Benefiting from this unique hollow homologous heterojunction, SMS(In)-7 obtains a CO generation rate as high as 11.23 μmol g–1 h–1 with visible-light irradiation, nearly 3 times enhancement over that of pure MOF-derived In2S3. This work provides a novel insight into the utilization of MOF-based platform for an efficient atomically heterojunction design.

Low-dimensional semiconductors exhibit remarkable performances in many device applications because of their unique physical, electrical, and optical properties. In this paper, we report a novel and facile method to synthesize In 2 S 3 quantum dots (QDs) at atmospheric pressure and room temperature conditions. This involves the reaction of sodium sulfide with indium chloride and using sodium dodecyl sulfate (SDS) as a surfactant to produce In 2 S 3 QDs with excellent crystal quality. The properties of the as-prepared In 2 S 3 QDs were investigated and photodetectors based on the QDs were also fabricated to study the use of the material in optoelectronic applications. The results show that the detectivity of the device stabilizes at ~ 10 13 Jones at room temperature under 365 nm ultraviolet light irradiation at reverse bias voltage.

In the present work, three different kinds of In 2 S 3 : hierarchical microspheres A, B and C (HMa, HMb and HMc), which were synthesized by a hydrothermal method in the sodium dodecyl sulfate-thiourea (SDS-thiourea) system. XRD, SEM and BET were used to characterize the prepared In 2 S 3 materials. Compared with the other two kinds of In 2 S 3 , the as-prepared In 2 S 3 hierarchical microspheres B (In 2 S 3 HMb) exhibit the best cataluminescence response to ammonium sulfide. The response and recovery times of the home-made ammonium sulfide gas sensor with In 2 S 3 hierarchical microspheres B as sensing materials were about 8 s and 24 s, respectively. The linear dependence of the sensitivity on the ammonium sulfide concentration was observed in the range of 4–200 ppm with an excellent selectivity. These results indicated that In 2 S 3 hierarchical microspheres B would be a good candidate for fabricating practical cataluminescence ammonium sulfide sensor.

A graphene quantum dots (GQDs) sensitized In 2 S 3 heterostructure photocatalyst was synthesized via a one-pot hydrothermal synthesis route. The high-resolution transmission electron microscope (HR-TEM) images reveal that the In 2 S 3 /GQD adopts the self-assembly three-dimensional flower-like nanostructure, in which In 2 S 3 forms the petal-like framework and the GQDs are grown on the surface of In 2 S 3 . The GQD has very high crystallinity and the loading amount of GQDs can be controlled during the synthesis process. The In 2 S 3 /GQDs catalyst exhibits extremely high adsorption capacity, photocatalytic activity and selectivity towards methylene blue. Under the identical experimental conditions, an optimum GQDs content of 1.09 wt% in the In 2 S 3 /GQDs nanocomposite resulted in 4.9 times higher dark adsorption rate and 3.7 times higher photodegradation rate for MB than pristine In 2 S 3 , making the In 2 S 3 /GQD a potential photocatalyst in water purification.

We fabricated a multidimensional heterostructured In2S3–CuInS2 photocatalyst to convert CO2 to CO. The hybrid photocatalyst can be obtained by using an In-containing MOF as a precursor followed by sulfidation and ion exchange. Moreover, the multidimensional structure, a 2D nanosheet semiconductor distributed on 1D hollow nanotubes, inhibits the recombination of charge carriers, increases CO2 adsorption and affords a large surface area promoting exposure of plentiful active sites. As a result, the as-synthesized optimal heterostructured In2S3–CuInS2 display a excellent activity with the CO evolution rate of 19.00 μmol g−1 h−1 over the under visible light irradiation, which is roughly four times higher than that of pristine In2S3. This work might pave the way for increasing the performance of metal sulphide photocatalysts by MOF-guided chemistry.

The design of efficient and stable photocatalysts for the removal of heavy metals in the environment has become a research hotspot. Here, a composite photocatalyst with three-dimensional In 2 S 3 microspheres supported by WO 3 nanoparticles was synthesized for the photoreduction of Cr(VI) for the first time. The constructed composite catalyst has a direct Z-scheme electron transport mechanism without any precious metals (Au, Pt, and Ag), quantum dots (TiO 2 QDs) or carbon materials (Graphene) as electronic media. Constructing a direct Z-scheme WO 3 /In 2 S 3 photocatalyst can greatly retain the reduction and oxidation reaction sites on the surface of the heterojunction and accelerate the reduction reaction. Under visible light irradiation, it greatly promotes the photocatalytic reduction of Cr(VI), which is 67.7 times and 3.6 times the reduction rates of WO 3 and In 2 S 3 , respectively. The favorable photocatalytic performance of WO 3 /In 2 S 3 should be attributed to the effective interfacial contact between the semiconductors in the Z-scheme system, thereby realizing effective electron transfer and charge separation. In addition, the stability of WO 3 /In 2 S 3 was studied, and a possible mechanism in the photoreduction process of Cr(VI) was proposed.

In this study, a composite heterojunction material of Ti 3 C 2 Tx MXene nanosheets with Co 9 S 8 @In 2 S 3 nanoparticles , named (Co 9 S 8 @In 2 S 3 )/MXene, was constructed using a hydrothermal method . The materials were characterized and analyzed in terms of morphology, structure, and selective response properties to triethylamine gas. The materials were characterized by SEM, TEM, HAADF, STEM, XRD , XPS, BET, and other tests. The results showed a response value of 44.9 for (Co 9 S 8 @In 2 S 3 )/20% MXene at 350 °C and 20 ppm triethylamine (TEA), with a response/recovery time of 63 s/115 s respectively. In particular, (Co 9 S 8 @In 2 S 3 )/MXene exhibits excellent immunity to interference and a highly stable adsorption/desorption process with almost no noise interference. In addition, the (Co 9 S 8 @In 2 S 3 )/MXene material showed stable and fast selective response to TEA in different types of gas mixtures compared with the commonly used single TEA selective response study method. The results of this study provide valuable techniques and theories for the Environmental protection application of TEA selective response materials. Finally, this article performs a comparative analysis on the mechanism of selection response and stability of (Co 9 S 8 @In 2 S 3 )/MXene materials, and concludes that the process determining the specific response of (Co 9 S 8 @In 2 S 3 )/MXene materials to particular gas molecules includes three processes: shape-selective adsorption, redox reaction , and charge carrier conduction.

Constructing advanced heterojunction structures is an effective approach to improve light utility and enhance photogenerated charge separation and transfer for solar energy conversion. Herein, we reported a MWCNT@MOF-derived In 2 S 3 hollow tube heterostructure via facile MOF sulfidation process, significantly boosting its photocatalytic degradation performance of tetracycline (TC) under visible light irradiation. The MWCNT bonds to the In 2 S 3 hollow tube strongly to construct an effective heterojunction, as illustrated in TEM and Raman spectroscopy. The 0.3%-MWCNT@MOF-derived In 2 S 3 exhibited the highest photocatalytic activity for visible-light-driven TC degradation, achieving ˜100% degradation efficiency, with its apparent reaction rate constants 3–5 times higher than that of the pure MOF-derived hollow In 2 S 3 and traditional In 2 S 3 bulk. The boosted visible-light-driven degradation efficiency was attributed to the synergy between electron acceptor of MWCNTs for enhanced separation of charge carriers and active center of MOF-derived In 2 S 3 hollow tube with shorter transfer distance of charge carriers, which not only promotes the carrier transfer and inhibits the recombination rate effectively, but also improves the visible light response. Such MOF-derived visible-light-active heterostructures thus provide a novel insight into the development of highly efficient photocatalyst for a wide usage.

Efficient utilization of full solar light especially near-infrared light (NIR) is still a great challenge. Herein three In 2 S 3 nanomaterials with cubic phase and different morphologies were synthesized via hydrothermal methods by using sodium sulfide (Na 2 S), thiosemicarbazide (TSC) and thioacetamide (TAA) as sulfur sources, respectively. All the as-synthesized In 2 S 3 samples were found to be photo-active under either UV, visible or NIR light irradiation although they possess very different morphologies. The In 2 S 3 sample with irregular and plate-like nanoparticles synthesized by using Na 2 S as sulfur source shows the highest activity on photodegradation of methyl orange due to its exposure of more photoactive (311) plane than the other two In 2 S 3 samples and the occurrence of lattice oxygen. The samples that synthesized by using TSC and TAA as sulfur sources possess the morphology of hollow microspheres, which are hierarchically constructed by thinner nanosheets and cumulated by thicker platelets, respectively. The microsphere sample constructed by thinner nanosheets shows even lower photocatalytic activity than that accumulated by thicker platelets under all the tested light regions especially under longer irradiation time because of its less exposed (311) plane and lower sulfur vacancies although it possesses a far larger specific surface area than the latter. These results suggest that the exposure of more photoactive (311) plane and occurrence of lattice oxygen deserve more attention to improve the photocatalytic activity of In 2 S 3 .

Photocatalytic ammonia production holds immense promise as an environmentally sustainable approach to nitrogen fixation. In this study, In2O3/In2S3-ZnCdS ternary heterostructures were successfully constructed through an innovative in situ anion exchange process, coupled with a low-temperature hydrothermal method for ZnCdS (ZCS) incorporation. The resulting In2O3/In2S3-ZCS photocatalyst was proved to be highly efficient in converting N2 to NH3 under mild conditions, eliminating the need for sacrificial agents or precious metal catalysts. Notably, the NH4+ yield of In2O3/In2S3-0.5ZCS reached a significant level of 71.2 μmol g−1 h−1, which was 10.47 times higher than that of In2O3 (6.8 μmol g−1 h−1) and 3.22 times higher than that of In2O3/In2S3 (22.1 μmol g−1 h−1). This outstanding performance can be attributed to the ternary heterojunction configuration, which significantly extends the lifetime of photogenerated carriers and enhances the spatial separation of electrons and holes. The synergistic interplay between CdZnS, In2S3, and In2O3 in the heterojunction facilitates electron transport, thereby boosting the rate of the photocatalytic nitrogen fixation reaction. Our study not only validates the efficacy of ternary heterojunctions in photocatalytic nitrogen fixation but also offers valuable insights for the design and construction of such catalysts for future applications.

3D (Three-dimensional) hollow porous structured materials received a lot of attention due to their significant benefits in photocatalytic reactions. In this study, 3D ZnIn 2 S 4 -In 2 S 3 hollow hierarchical porous nanotubes were synthesized by a one-step MOF (metal–organic framework) templating strategy as efficient catalysts for photocatalytic hydrogen evolution in water. The dynamic process between the internal collapse of In-MIL-68 and the growth of ZnIn 2 S 4 crystals with attached outer edges led to the one-step in situ preparation of hollow ZnIn 2 S 4 -In 2 S 3 heterojunction catalysts. Crucially, In-MIL-68 simultaneously induced the formation of In 2 S 3 hollow porous nanotubes and the construction of ZnIn 2 S 4 -In 2 S 3 hierarchical heterojunction with ultrathin nanosheets. The optimal photocatalytic efficiency was obtained by adjusting the relative composition of the two-component heterojunction, and the optimized ZnIn 2 S 4 -In 2 S 3 -10 showed hydrogen evolution efficiency of 5.01 mmol·h −1 ·g −1 under visible light irradiation in the absence of co-catalysts and a high AQY (the apparent quantum yield) of 16.23 % at 420 nm, which was noticeably higher than the photocatalytic efficiency of the one-component and two-step synthesized In 2 S 3 -ZnIn 2 S 4 . Both theoretical and experimental results demonstrated that the construction of heterojunction and the forming of hollow porous nanotubes enhanced visible light absorption and promoted the separation and transfer of photogenerated carriers, thereby increasing the photocatalytic activity of the prepared materials. Meanwhile, ZnIn 2 S 4 -In 2 S 3 hierarchical hollow nanotubes exhibited good stability and reusability, offering a new way to fabricate MOF-based hollow hierarchical photocatalysts.
