Constructing heterostructures is an effective strategy to improve the performance of semiconductor metal oxide . The heterostructure exhibits strong interaction between tightly packed interfaces, showing better performance than a single structure. Therefore, indium sulfide (In 2 S 3 )/tungsten oxide (WO 3 ) composites were synthesized with heterojunction by a simple hydrothermal method to enhance the gas sensing performance of WO 3 . The WO 3 and In 2 S 3 exist in the form of nanoparticles . Then the gas sensing test of the material was carried out, by exploring the performance of WO 3 based on doping different amounts of In 2 S 3 , the response of WO 3 based on 3 wt% In 2 S 3 to 10 parts per million (ppm) nitrogen dioxide (NO 2 ) is 170.1 at the optimum operating temperature of 170 °C. Compared with pure WO 3 , the response is enhanced by seven times. Besides, the detection limit of the sample is low. The minimum detection concentration of NO 2 can reach 20 parts per billion (ppb). The reason for the improved performance can be attributed to the wider electron depletion layer or hole accumulation layer formed by the heterojunction for electron transfer . Finally, a convenient wearable NO 2 Real-time Detection System is designed to detect different concentrations of NO 2 in the factory, which provides an effective alarm mean for the excessive emission of industrial waste gas in the factory environment.

Using Cobalt 2-methylimidazole (ZIF-67) as the precursor, Co 9 S 8 /In 2 S 3 was successfully synthesized. The characteristic structure of Co 9 S 8 /In 2 S 3 is Co Metal-Organic framework (Co-MOF). Co 9 S 8 /In 2 S 3 semiconductor material was prepared by the hydrothermal method , which presented a special multi-wrinkled flower-like morphology. The Co 9 S 8 /In 2 S 3 semiconductor material has selectivity and high sensitivity to triethylamine (Rair/Rgas=100.3, 20 ppm), ultra-low detection limit (100 ppb), and good linearity relation at working temperature of 300 °C. The products were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD). The growth mechanism of these products was proposed. A possible mechanism to explain the high sensing properties of these morphologies was that the Co 9 S 8 /In 2 S 3 material had p-n heterojunction structure characteristics, coupled with its high porosity and specific surface area on the morphology helped to improve the sensitivity to triethylamine (TEA).

Inorganic semiconductors prepared from MOFs as sacrificial precursors are promising photocatalytic materials. In this work, the direct Z -scheme MoS 2 /NH 2 -MIL-68(In)-derived In 2 S 3 (MoS 2 /In 2 S 3 ) heterojunction composites have been synthesized by sulfidation treatment of MoS 2 /NH 2 -MIL-68(In) (MoS 2 /NM68) composites. Morphological and crystal structural results confirmed that MoS 2 was uniformly dispersed in In 2 S 3 . According to the reduction for Cr(VI) experimental results, the photocatalytic performance of MoS 2 /In 2 S 3 heterojunction composite under visible light irradiation is significantly better than that of pristine MoS 2 and In 2 S 3 , respectively. In addition, the photocatalytic activities of the MoS 2 /In 2 S 3 (II) at different pH and high concentrations of Cr(VI) were also investigated. This paper presents a novel approach to the construction of heterojunction photocatalytic materials using MOFs as sacrificial precursors.

Photocatalytic conversion of polylactic acid (PLA) plastic waste into value-added chemicals offers a promising approach for sustainable development. However, achieving high selectivity toward a desired product in the conversion remains challenging due to uncontrolled formation of oxygenated intermediates. Herein, we demonstrate a highly selective strategy for converting lactic acid (LA) derived from PLA hydrolysis into acetic acid, which is achieved by precisely regulating radical generation using a sulfur-doped BiVO 4 /In 2 S 3 (S-BiVO 4 /In 2 S 3 ) S-scheme heterojunction. DFT theoretical calculations and in-situ electron paramagnetic resonance results reveal that sulfur doping reduces the formation energy of V 4+ from V 5+ in BiVO 4 , facilitating electron transfer and O 2 dissociation. This promotes •OH radical generation via a proton-coupled electron transfer process by supplying protons to lower the •OH formation barrier. Consequently, •COCH 3 intermediates selectively interact with •OH radicals to form acetic acid. The optimized S-BiVO 4 /In 2 S 3 catalyst achieves an acetic acid generation rate of 3.97 mmol g −1 h −1 with an apparent quantum efficiency (AQE) of 1.42 % at 360 nm. Moreover, the acetic acid selectivity at S-BiVO 4 /In 2 S 3 reaches 84.3 %, which is significantly higher than that of its counterpart, pristine BiVO 4 (27.3 %). The present work opens a new avenue for designing efficient photocatalysts to selectively convert waste plastics into value-added products.

As a result of their radiation-free nature and deep-penetration ability, tumor theranostics mediated by ultrasound have become increasingly recognized as a modality with high potential for translation into clinical cancer treatment. The effective integration of ultrasound imaging and sonodynamic therapy (SDT) into one nanoplatform remains an enormous challenge yet to be fully resolved. Here, a novel theranostic system, consisting of rattle-type SiO2 (r-SiO2) loaded with Mn-doped In2S3/InOOH (SMISO), was designed and synthesized to enable an improved ultrasound imaging-guided therapy. With Mn-doped In2S3/InOOH (MISO) and a heterojunction structure, this novel sonosensitizer facilitates the generation of reactive oxygen species (ROS) for SDT. By coupling interfaces between the shell and core in rattle-type SiO2, multiple reflections/scattering are generated, while MISO has high acoustic impedance. By integrating r-SiO2 and MISO, the SMISO composite nanoparticles (NPs) increase the acoustic reflection and provide enhanced contrast for ultrasound imaging. Through the effective accumulation in tumors, which was monitored by B-mode ultrasound imaging in vivo, SMISO composite NPs effectively inhibited tumor growth without adverse side effects under ultrasound irradiation treatment. This work therefore provides a new approach to integrate a novel gas-free ultrasound contrast agent and a semiconductor sonosensitizer for cancer theranostics.

High-efficiency interfacial charge transfer is the key to achieve better spatial carrier separation, and thus to develop advanced heterogeneous photocatalysts for environmental remediation. However, It still remains a great challenge to design and exploit the effective charge transfer scheme. Herein, a novel Z-scheme In 2 S 3 /BiOBr with S−O covalent bonding was prepared by hydrothermal and subsequent thermal annealing methods. The obtained photocatalysts were systematically characterized and used for tetracycline hydrochloride degradation and Cr(VI) reduction in aqueous solution. As a result, the optimized In 2 S 3 /BiOBr heterostructure (IS/BOB-39) exhibited superior photocatalytic activities for tetracycline hydrochloride degradation and Cr(VI) reduction under simulated solar light irradiation compared with individual materials. The Z-scheme transfer mechanism was corroborated by trapping experiments, ESR and XPS analysis , which provided an effective transfer pathway for spatial separation of carriers. Moreover, the formation of chemical S−O bond between In 2 S 3 and BiOBr, which acted as a specific bridge to expediently transmit interfacial electrons, showed a synergistic effect with Z-scheme transfer model on the significantly enhanced photocatalytic performance. In addition, the In 2 S 3 /BiOBr heterojunction presented excellent cycle stability, resulting from the tight heterointerface. This work provides a promising approach to design and fabricate high effect Z-scheme heterojunction in wastewater treatment.

This work designed a new photoelectrochemical (PEC) immunoassay for the ultrasensitive detection of alpha-fetoprotein (AFP) based on the flower-like β-In 2 S 3 @carbon dots (CDs). The photocurrent of the as-prepared heterogeneous nanostructure was enhanced significantly under ultraviolet (UV), visible (Vis) and near-infrared (NIR) irradiation thanks to the more generation of carriers and less electron-hole pairs recombination with CDs. The three-layer sandwich-like immunocomplex would be formed upon the target AFP existed, the ascorbic acid 2-phosphate (AA2P) was subsequently transformed into ascorbic acid (AA) owing to the catalysis of alkaline phosphatase-conjugated rabbit polyclonal anti-human AFP (ALP-Ab2). Without additional applied voltage, the photocurrent of the β-In 2 S 3 @CDs-modified electrode was positively correlated with the increasing AA level in the detection cell. Under optimal conditions, the developed PEC immunosensing platform exhibited good reproducibility and high sensitivity for the determination of target AFP within a dynamic working range from 0.5 to 50 ng mL −1 at a detection limit of 37.9 pg mL −1 . In addition, the method accuracy relative to human AFP ELISA kit was evaluated by analyzing human serum specimens, and a good match between two methods was obtained. Such the increasing photocurrent through full-spectrum responsive mode gives a new horizon to develop highly sensitive PEC immunoassay in early clinical diagnosis by monitoring disease-related biomarkers.

Currently, Cr(VI) poses a great threat to the human health and ecosystem due to its acute toxicity and potential carcinogenicity. In order to quickly and efficiently reduce Cr(VI) to Cr(III) by photocatalysis , a new In 2 S 3 -ZnIn 2 S 4 heterostructure hierarchical microtubes, which is based on the combination of the main three strategies for the enhancement of photocatalysts’ performance including semiconductor heterostructure, hierarchical microstructure, and hollow morphology, were designed and successfully synthesized via a facile liquid chemical treatment of metal-organic frameworks pre-synthesized as a self-sacrificing template. The microstructure, composition and photocatalytic properties of In 2 S 3 -ZnIn 2 S 4 composite were investigated by means of SEM, TEM, XRD , XPS, PL and electrochemical techniques . The photocatalytic reduction performance of In 2 S 3 -ZnIn 2 S 4 composites are much better than that of pure In 2 S 3 and ZnIn 2 S 4 under visible light irradiation . For the best photocatalytic activity of the as-prepared sample, the Cr(VI) with the initial concentration of 80 mg/L in the water can be photocatalytic reduced 93.4% in 10 min under visible light irradiation, which meet the requirement of design well.

Uncovering the excitation processes of photocatalysts and enhancing the dissociation of excitons into free photogenerated electrons and holes for photocatalytic CO 2 reduction is imperative yet quite challenging. Herein, an efficient strategy of reducing the binding energy of excitons to boost exciton dissociation is reported by anchoring the low valence single-atom Cu sites in In 2 S 3 nanosheets (Cu-In 2 S 3 ), which can enhance photocatalytic CO 2 reduction activity. The investigations of photo-irradiated Kelvin probe force microscopy (KPFM), in situ irradiates X-ray photoelectron spectroscopy (XPS), and temperature-dependent photoluminescence (TD-PL) indicate that the doping of low valence single-atom Cu can efficiently drive the charge transfer and separation. Moreover, the studies of the dynamic behaviors of charge carriers by femtosecond time-resolved spectroscopy (fs-TAS) reveal that the doping of low valence Cu single-atom sites allows the promotion of exciton dissociation by reducing the binding energy of the exciton, resulting in an enhanced photocatalytic CO 2 reduction of Cu-In 2 S 3 nanosheets. The aforementioned strategy for enhancing the dissociation efficiency of excitons in photocatalysts will offer a highly efficient and promising approach for the photocatalytic CO 2 reduction and other photocatalytic applications.

Herein, Ag/In2S3/ZnO nanorods (NRs) composite photocatalysts were successfully prepared via simple methods. Significantly, hydroxyl radical active substances were found in the electron spin resonance tests of In2S3/ZnO NRs and Ag/In2S3/ZnO NRs, which indicates that the oxidation reaction that oxidizes water or hydroxide ions into hydroxyl radicals occurs on the valence band of ZnO NRs. It suggests that Z-scheme heterojunction was successfully constructed. In the photocatalytic experiments of degrading 4-nitrophenol (PNP), the Ag/In2S3/ZnO NRs composite exhibits higher photocatalytic activity than ZnO NRs, In2S3, Ag/ZnO NRs and In2S3/ZnO NRs. The characteristic peak of PNP disappears completely in 50 min. The enhanced photocatalytic performance can be attributed to the formation of Z-scheme heterojunction between ZnO NRs and In2S3. In addition, local surface plasmon resonance of Ag and Schottky junction formed between Ag and In2S3 also promote the photocatalytic activity.

Preeclampsia constitutes a critical and severe complication of gestational hypertension in pregnant women. At present, there exists no effective treatment for preeclampsia, although placental growth factor (PlGF) has been identified as the most reliable predictive biomarker. Consequently, the accurate quantification of PlGF levels in the blood of pregnant women affected by preeclampsia is imperative. In this study, a microfluidic photoelectrochemical immunosensor based on ZnIn 2 S 4 /In 2 S 3 heterojunction photosensitive material was developed on fluorine-doped tin oxide (FTO) and integrated with microfluidic channels. This innovative platform enables the detection of PlGF, an eclampsia marker, in pregnant women. Following activation with chitosan (CTS) and glutaraldehyde (GA), the immobilized monoclonal antibody specific to PlGF forms a covalent bond with its corresponding antigen, and the interaction is detected through changes in photocurrent. The experimental results indicate that the proposed sensor exhibits a wide detection range of 0.1 pg mL⁻¹ to 1 µg mL⁻¹ for PlGF, with a limit of detection (LOD) of 0.0879 pg mL⁻¹ (S/N = 3). Additionally, the sensor demonstrates excellent specificity, stability, reproducibility, low sample consumption, and robust detection performance for clinical specimens. Therefore, this sensor holds significant promise as an auxiliary diagnostic tool for early screening of eclampsia-related conditions in pregnant women.
