Hydrogen peroxide (H 2 O 2 ) is a green oxidant that is widely used in daily life and industry. Artificial photocatalytic synthesis of H 2 O 2 is a green and sustainable scheme, but the high complexation rate of electron-hole pairs during photocatalysis and the low activation capacity of the catalyst for O 2 greatly inhibit the oxygen reduction reaction. Herein, the first synergistic modification of In 2 S 3 using ion doping and vacancy modulation is used in this paper. An In 2 S 3 -based photocatalyst containing S vacancies and Ga 3+ ions is designed and synthesized. After continuous irradiation under visible light ( λ ≥ 420 nm) for 1 h, the H 2 O 2 concentration of the system reaches 352.58 μmol L –1 , which is 7.5 times than that of pure In 2 S 3 , and the apparent quantum yield at 450 nm is 4.64%. Appropriate concentrations of S vacancies promoted O 2 adsorption, and theoretical calculations demonstrates that Ga 3+ ions and S vacancies synergistically promote O 2 activation and more favorable for 2e – oxygen reduction reaction. All these phenomena facilitate H 2 O 2 generation. Furthermore, ESR analysis and radical trapping experiments show that the interaction between superoxide anion radicals (•O 2 – ), singlet oxygen ( 1 O 2 ), h + , and proton donor (isopropanol) in the solution phase plays a key role in the photocatalytic synthesis of H 2 O 2 , which has been largely neglected in previous studies. We suggest that the S vacancy-regulated Ga 3+ ion-doped In 2 S 3 catalyst could provide a reference for the design of high-performance materials for the photocatalytic production of hydrogen peroxide.

Cotton cellulose nanofibers (CCNFs)/In2S3/Ag–CdS nanocomposites were prepared by a typical technical route which combined electrospinning and a chemical method. The results showed that the CCNFs/In2S3/Ag–CdS nanocomposites had a remarkable visible light photocatalytic property and cycling stability, which displayed a significant enhancement compared with that of pure In2S3. Through analysis, this enhancement could be mainly attributed to the multilevel structure of the composites.

Molecular responsive materials with fast, stable, and specific selectivity are a key focus of chemical sensor technology research. In the field of triethylamine (TEA) sensor technology, developing TEA-selective responsive materials with superior performance is of great significance for promoting technological progress and industrialization of TEA sensor technology. In this study, MXene/In 2 S 3 micro-nano powder was prepared by combining Ti 3 C 2 Tx-type MXene with nano-sized In 2 S 3 . The morphology, structure, and structure-performance relationship of the material were characterized and analyzed using SEM, TEM, XRD, HAADF, and XPS. Through experiments, it was confirmed that MXene/In 2 S 3 exhibited outstanding specific selectivity to TEA. At a TEA concentration of 20 ppm and a temperature of 210 °C, the response value of the material to TEA was 8.74, while other typical gas molecules such as aldehydes, ketones, and aromatics showed almost no response, demonstrating excellent selectivity for TEA molecules. The response/recovery time was 19 s/42 s, and the response value was stable over 20 consecutive cycles, indicating excellent reliability of the material. In addition, in the concentration range of 1–500 ppm, the response value of the MXene/In 2 S 3 material to TEA concentration followed an exponential fitting of the asymptotic model, with the formula y = a-b*c x and R 2 of 0.99472. Furthermore, the selection and response process of MXene/In 2 S 3 micro-nano materials and TEA molecules were analyzed from the molecular internal structure, and it was found that the selective response characteristics of the material to TEA were related to its microstructure, including shape adsorption.

Three-dimensional hollow tube-like structures have obtained considerable attention owing to their pronounced advantages in photocatalytic reactions. Herein, metal organic framework (MOF)-derived MnIn 2 S 4 @In 2 S 3 with hollow tube-like structure was successfully synthesized through a facial hydrothermal combined solvothermal method. Electron spin resonance technology and radical scavengers verified that holes and superoxide anions are the primary reactive species in the photocatalytic reaction. The resulting hollow tube-like MnIn 2 S 4 @In 2 S 3 (MnIS) composite exhibits superior H 2 O 2 yield and ofloxacin photodegradation performance, which are much higher than those of pure MnIn 2 S 4 and In 2 S 3 samples. The experimental results along with density functional theory (DFT) calculations indicate that the co-sharing of In and S elements in MnIn 2 S 4 and In 2 S 3 within the MnIS composites induces strong interface interactions. Additionally, the generation and decomposition of H 2 O 2 provide more active sites, thereby facilitating the photodegradation of ofloxacin. Meanwhile, the formation of an S-scheme heterojunction between MnIn 2 S 4 and In 2 S 3 promotes swifter charge separation and transfer, leading to superior performance in terms of H 2 O 2 evolution and ofloxacin degradation. This investigation offers a novel insight by co-constructing MOF-derived hollow nanotubes and heterojunctions for achieving highly efficient photocatalytic solar-to-fuels conversion.

Cocatalysts have been extensively employed to improve gas sensing performance in gas detection. However, the interface effect of the heterojunction on gas sensing has rarely been addressed. This study investigated the interface effect of constructive hierarchical In 2 S 3 /In 2 O 3 nanoflowers on NO 2 gas sensitivity using a rapid and facile microwave-assisted hydrothermal method. The structure was then modulated from In 2 S 3 , to In 2 S 3 /In 2 O 3 heterostructures, and finally In 2 O 3 alone by increasing the calcination time. In 2 S 3 /In 2 O 3 heterostructures with an appropriate interface were found to significantly promote NO 2 gas sensitivity with a high gas-sensing selectivity compared with pure In 2 S 3 and In 2 O 3 . An interface enhancement model has also been developed. The strong interfacial coupling effect was key to high gas sensitivity, which likely originated from hole–electron pair separation through tuning of the interfacial electronic structure of In 2 S 3 /In 2 O 3 nanoflowers using different calcination times. This resulted in improved charge separation efficiency and carrier collection efficiency of electrons from In 2 S 3 to In 2 O 3 , and increased active sites. This boosted gas diffusion and adsorption, accelerated surface chemical reactions, and expedited charge transport and kinetic processes. This work provides a new approach for designing high-performance sensor using the interface effect of heterostructure nanomaterials.

In this paper, PDA n /CeO 2 /In 2 S 3 -X (X = m(CeO 2 )/m(CeO 2 +In 2 S 3 ), n = m(PDA)/ m(catalyst)) heterojunction was successfully fabricated by three steps to detect glucose and hexavalent chromium (Cr(VI)). CeO 2 was initially synthesized by calcination , followed by a hydrothermal method to make In 2 S 3 compounded with CeO 2 . Specifically, by optimizing the ratio of CeO 2 and In 2 S 3 , CeO 2 /In 2 S 3 -15 % showed the best photoelectric responses and sensing performances. In order to further improve the performance, polydopamine (PDA) was modified on the surface of CeO 2 /In 2 S 3 -15 % (PDA n /CeO 2 /In 2 S 3 -15 %). Besides, the results from optical characterizations and performance testings showed that PDA 0.1 /CeO 2 /In 2 S 3 -15 % exhibits the best absorption capacity and photocurrent responses. Interestingly, PDA 0.1 /CeO 2 /In 2 S 3 -15 % was applied to detect Cr(VI) and glucose in an effective fashion. The PEC glucose sensor based on PDA 0.1 /CeO 2 /In 2 S 3 -15 % showed an acceptable detection range between 0.5 μM and 27 mM with good sensitivity (575.20 µA·mM −1 ·cm −2 ) and low detection limit (0.076 μM). Meanwhile, for Cr(VI) sensing, it has a wide linear range of 0.5–240 µM with a high sensitivity of 1053.60 µA·mM −1 ·cm −2 , and the low detection limit is 0.098 µM. Furthermore, it could be also employed in real samples (human blood serum or sewage). Thus, the PEC sensor based on PDA/CeO 2 /In 2 S 3 has potential applications in glucose and Cr(VI) detection.

Graphical Interface construction through experimental control of the introduced anions allows the tuning of the energy bands of photoanode materials. The cooperative energy band and electronical structure of In 2 O 3 /In 2 S 3 resulted in a photocurrent of 0.6 mA⋅cm −2 when exposed to light irradiation. This strategy has practical significance for developing low-cost, high-performance PEC sensors. In the past several decades, Photoelectrochemical (PEC) sensing still remains a great challenge to design highly-efficient semiconductor photocatalysts via a facile method. It is of much importance to design and synthesize various novel nanostructured sensing materials for further improving the response performance. Herein, we present an In 2 O 3 /In 2 S 3 heterostructure obtained by combining microwave assisted hydrothermal method with S-induced phase change, whose energy band and electronic structure could be adjusted by changing the S content. Combining theoretical calculation and spectroscopic techniques, the introduction of sulfur was proved to produce multifunctional interfaces, inducing the change of phase, oxygen vacancies and band gap, which accelerates the separation of photoexcited carriers and reduces their recombination, improving the electronic injection efficiency around the interface of In 2 O 3 /In 2 S 3 . As anticipated, an enhanced glucose response performance with a photocurrent of 0.6 mA cm −2 , a linear range of 0.1–1 mM and a detection limit as low as 14.5 μM has been achieved based on the In 2 O 3 /In 2 S 3 heterostructure, which is significant superior over its pure In 2 O 3 and S-doped In 2 O 3 counterparts. This efficient interfacial strategy may open a new route to manipulate the electrical structure, and energy band structure regulation of sensing material to improve the performance of photoelectrodes for PEC.

Hexagonal Zn–Al hydrotalcite (Zn–Al LDHs) has become a research hotspot in the field of photocatalysis due to efficient photocatalytic performance, low cost and non-toxicity. In this research, In 2 S 3 /Zn–Al LDHs composites were firstly synthesized by one-pot method with InCl 3 and TAA as raw materials. The crystalline structure, surface morphology , chemical composition, together with optical properties of the samples were investigated by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectra (FT-IR), UV–Vis diffuse reflectance spectrometry (DRS), and Photoluminescence spectra (PL). The photocatalytic performance of the composite photocatalyst was investigated by degradation of tetracycline (TC) under visible-light irradiation. The photochemical properties and cyclic stability of the photocatalyst were further explored. Experimental results display that the photocatalytic efficiency of In 2 S 3 /Zn–Al LDHs (1:2) was remarkably superior to that of pure In 2 S 3 and Zn–Al LDHs. In 2 S 3 /Zn–Al LDHs (1:2) composite showed high photocatalytic activity for TC degradation (92.2% within 30 min). The modification of Zn–Al LDHs by In 2 S 3 prompted the separation of photogenerated electron-hole pairs and thus improved the photocatalytic performance. It can be inferred that the efficient photocatalytic performance of In 2 S 3 /Zn–Al LDHs composites could remove many hazardous pollutants in wastewater.

Developing high-efficiency and low-cost hydrogen production catalysts is essential to alleviate environmental problems. Indium sulfide is an effective catalyst for photocatalytic water-splitting reactions to produce hydrogen (H2). However, the high hole–electron recombination rate of indium-based nanoparticles restricts their practical applications. To overcome this, we fabricated a P-doped In2S3 catalyst with S vacancies through a calcination method. When the P-doping magnitude is 0.4 wt%, the resultant catalyst reports the optimal photo-catalytic activity (3853.4 μmol h−1 g−1) in the presence of formaldehyde, molecular oxygen and visible light illumination, which is more than 6.3 times higher than that of pure In2S3 (603.3 μmol h−1 g−1). The synergetic effect of sulfur vacancies and the P-doping can lead to a narrower band gap in the In2S3 nanoparticles, thereby promoting photogenerated hole–electron pair separation and photo-catalytic hydrogen production ability. We find that molecular O2 plays a crucial role in promoting the oxidation of formaldehyde to produce photo-catalytic H2. During the entire reaction process, molecular oxygen will not be consumed (similar to a cocatalyst). Benefiting from the enhanced charge separation and transfer processes, the P-doped In2S3 with S vacancies exhibits excellent photo-catalytic hydrogen production performance from formaldehyde solution.

The development of high-efficiency photocatalysts is of great importance to realize robust solar-driven CO2 conversion; however, the low carrier separation efficiency and poor light absorption ability usually limit the performance of the photocatalysts. Herein, a hollow In2S3/polymeric carbon nitride (IS/CN) heterojunction was prepared via electrostatic self-assembly and in situ sulfidation under solvothermal conditions. The intimate interfacial contact between the IS and CN facilitates the construction of an effective heterojunction, as demonstrated by X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM). The optimized IS/CN-5 sample exhibits a high CO evolution rate of 483.4 μmol g–1 h–1, which is 99 and 6 times as high as that of IS and CN, respectively. The improved charge separation and transfer efficiency, the hollow nanotube structure, and the enhanced CO2 adsorption ability are the reasons for the excellent photocatalytic activity. Besides, a possible photocatalytic mechanism of CO2 reduction by the IS/CN heterojunction was proposed on the basis of the band structures. This work provides an effective and facile strategy to construct hollow semiconductor heterojunctions for photocatalytic applications.

The construction of Z-scheme photocatalyst materials mimicking the natural photosynthesis system provides many advantages, including increased light harvesting, spatially separated reductive and oxidative active sites and strong redox ability. Here, a novel Bi 2 S 3 nanorod@In 2 S 3 nanoparticle heterojunction photocatalyst synthesized through one-pot hydrothermal method for Cr 6+ reduction is reported. A systematic investigation of the microstructural and compositional characteristics of the heterojunction catalyst confirms an intimate facet coupling between (440) crystal facet of In 2 S 3 and (060) crystal facet of Bi 2 S 3 , which provides a robust heterojunction interface for charge transfer. When tested under visible-light irradiation, the Bi 2 S 3 –In 2 S 3 heterojunction photocatalyst with 15% Bi 2 S 3 loading content achieves the highest Cr 6+ photoreduction efficiency of nearly 100% with excellent stability, which is among the best-reported performances for Cr 6+ removal. Further examination using optical, photoelectrochemical, impedance spectroscopy, and electron spin resonance spectroscopy characterizations reveal greatly improved photogenerated charge separation and transfer efficiency, and confirm Z-scheme electronic structure of the photocatalyst. The Z-scheme Bi 2 S 3 –In 2 S 3 photocatalyst demonstrated here presents promise for the removal of highly toxic Cr 6+ , and could also be of interest in photocatalytic energy conversion.

Perovskite solar cells (PSCs) have attracted significant attention in recent years owing to some of their advantages: high-efficiency, low cost and ease of fabrication. In perovskite photovoltaic devices, charge transport layers play a vital role for selectively extracting and transporting photo-generated electrons and holes to opposite electrodes. Therefore, it is very important to prepare high-quality charge transport layers using simple processes at low cost. As reported, In2S-based electron selective layers display excellent performance including high solar-cell efficiency and negligible hysteresis. In this study, a simple chemical method was developed to prepare In2S3 thin films as the electron selective layers in organic–inorganic hybrid perovskite photovoltaic devices to shorten the fabrication time and simplify the technology, which can provide a new avenue for a low-cost and solution-processed method. By optimizing the preparation conditions, it was demonstrated that In2S3 thin film prepared using our straightforward chemical approach have higher electron extraction efficiency and comparable efficiency compared with archetypical TiO2 as the electron transport layer (ETL) in perovskite photovoltaic device.
