CdS–In 2 S 3 heterojunction with enhanced photoelectrochemical (PEC) performance was synthesized to construct dual-mode visible light-induced biosensors for highly sensitive and selective detection of bleomycin (BLM). Due to improved absorption in the visible region and suppressed recombination of electron-hole pairs in the heterojunction, CdS–In 2 S 3 composite exhibited enhanced photocurrent response under visible light illumination. Using CdS–In 2 S 3 as photoactive materials and BLM-binding aptamer as recognition element, a PEC aptasensor displaying a declined photocurrent response to BLM was facilely constructed, which was linear to BLM concentration in the range of 5.0–250 nM. On the other hand, the CdS–In 2 S 3 photoanode was employed to construct a photofuel cell (PFC). In such a PFC, the oxidation of water on CdS–In 2 S 3 photoanode under visible light illumination and the reduction of oxygen on Pt cathode led to the generation of electricity. When BLM-binding aptamer was immobilized on CdS–In 2 S 3 photoanode, the output power of the PFC was inversely proportional to the logarithm of BLM concentration from 10 to 250 nM, offering a visible light-induced self-powered sensing platform for BLM detection. Both of the proposed sensors showed high selectivity , good reproducibility and high stability. They were successfully applied to the determination of BLM in human serum samples.

All-inorganic CsPbBr 3 perovskite solar cells (PSCs), which show potential applications in the semitransparent top cell of tandem solar cells, have attracted tremendous attention owing to their outstanding thermal and moisture stability in an air atmosphere. However, the common solution-processed CsPbBr 3 perovskite films usually suffer from poor phase purity due to the local uncontrolled ratio of CsBr and PbBr 2 . Herein, a novel 2-methoxyethanol solvent for CsBr is used in place of methanol to yield high-quality CsPbBr 3 films with better phase purity as well as larger and more uniform grains. Meanwhile, a facile and controllable reflux condensation technique is proposed to prepare In 2 S 3 thin films for the electron transport layer (ETL) of CsPbBr 3 PSCs. Therefore, the power conversion efficiency (PCE) of all-inorganic planar CsPbBr 3 PSCs with the architecture of FTO/In 2 S 3 /CsPbBr 3 /carbon is increased from 5.83% to 6.42%. By adjusting the reflux condensation temperature (80, 100, 120, or 140 °C) and tailoring the aggregation of In 2 S 3 colloidal particles, In 2 S 3 thin films with different surface roughnesses are synthesized to optimize the ETL of the devices, which further enhances the short-current density and boosts the PCE to 6.54%.

The excellent electrochemical performance of indium sulfide (In 2 S 3 ) in lithium ion batteries (LIBs) and sodium ion batteries (SIBs) prompted us to explore its energy storage mechanism in potassium ion batteries (PIBs). In this work, In 2 S 3 /C nanofibers are successfully synthesized by simple electrospinning and subsequent vulcanization . In K half cells, compared to commercial In 2 S 3 electrodes, In 2 S 3 /C nanofibers as anode materials for PIBs show outstanding electrochemical performance, which can deliver reversible capacities of 397.6 (25), 366.2 (50), 335.2 (100), 307.8 (200), 260.4 (500) and 212.2 mAh g −1 (1000 mA g −1 ), respectively. In K full cells, In 2 S 3 /C nanofibers can also show good potassium storage performance and can light up 15 light emitting diodes (LEDs). The superb electrochemical performance of In 2 S 3 /C nanofibers is due to the in-situ composite with self-nitrogen-doped carbon matrix and the nanoization of In 2 S 3 particles, which buffers the volume effect and improves the conductivity of the material during the potassium storage process. In addition, the mechanism of potassium storage of In 2 S 3 /C nanofibers was systematically studied by cyclic voltammetry (CV), ex-situ XRD, TEM and XPS methods. The mechanism of In 2 S 3 for K-ion storage can be described as the conversion reaction: In 2 S 3 + 6K + + 6e − ⇌ In + 3K 2 S.

In this work, ultrathin lamellar g-C 3 N 4 /In 2 S 3 S-scheme heterojunctions doped with P were synthesized by urea recrystallization and investigated to see which ratio was more favorable for photocatalysis. The P doping formed a new Fermi energy level and reduced the forbidden bandwidth. The ultrathin lamellar structure facilitated rapid charge transfer, and the formation of S-scheme heterojunction, the presence of the interfacial electric field, and band bending effectively separated strong redox-capable electron-hole pairs, thus significantly improving the photocatalytic performance. Among the prepared materials, the 50UP-C 3 N 4 /In 2 S 3 photocatalyst with 50 % UP-C 3 N 4 mass fraction showed optimal photocatalytic H 2 production performance, with a hydrogen production rate of 12,387 μmol h −1 g −1 . Moreover, it showed good performance in photocatalytic degradation, with a degradation efficiency of up to 90.2 % of ofloxacin after 120 min of light exposure. This article provided a new perspective on the synthesis of other photocatalysts with carbazide-based S-scheme heterojunction structures.

Photoelectrochemical (PEC) water splitting via semiconductors is an effective and feasible method for synthesizing renewable hydrogen (H 2 ) fuels. In this study, β-In 2 S 3 nanosheets were first grown on conductive glass. Then, we prepared P-doped β-In 2 S 3 nanosheets with an amorphous InPO x overlayer via the incomplete phosphorization of pristine β-In 2 S 3 nanosheets. When we used this material as photoanode in a PEC cell for water splitting, the photocurrent density drastically increased to 2.2 mA cm −2 at 1.23 V versus a reversible hydrogen electrode (vs. RHE). It enhanced 15 times as the pristine β-In 2 S 3 nanosheets, which was only 0.15 mA cm −2 at 1.23 V vs. RHE (solar standard spectrum, 100 mW cm −2 ). The photoelectric conversion efficiency as high as 0.65% at a low potential of 0.81 V vs. RHE was achieved for the phosphorized β-In 2 S 3 nanosheets. A series of experiments proved that the P-doping accelerated semiconductor charge-transport and the InPO x overlayer played cocatalyst role. We penetratingly investigated the pathway of charge transfer via femtosecond transient absorption. The results showed one pathway of charge transfer in pristine β-In 2 S 3 photoanode. However, there were two pathways (core/shell coupling and shallow trap states) for charge transfer in the phosphorized β-In 2 S 3 photoanode, which improved the performance of its PEC water oxidation.

Photocatalytic production of hydrogen peroxide (H 2 O 2 ) is an ideal pathway for obtaining solar fuels. Herein, an S-scheme heterojunction is constructed in hybrid TiO 2 /In 2 S 3 photocatalyst, which greatly promotes the separation of photogenerated carriers to foster efficient H 2 O 2 evolution. These composite photocatalysts show a high H 2 O 2 yield of 376 µmol/(L·h). The mechanism of charge transfer and separation within the S-scheme heterojunction is well studied by computational methods and experiments. Density functional theory and in-situ irradiated X-ray photoelectron spectroscopy results reveal distinct features of the S-scheme heterojunction in the TiO 2 /In 2 S 3 hybrids and demonstrate charge transfer mechanisms. The density functional theory calculation and electron paramagnetic resonance results suggest that O 2 reduction to H 2 O 2 follows stepwise one-electron processes. In 2 S 3 shows a much stronger interaction with O 2 than TiO 2 as well as a higher reduction ability, serving as the active sites for H 2 O 2 generation. The work provides a novel design of S-scheme photocatalyst with high H 2 O 2 evolution efficiency and mechanistically demonstrates the improved separation of charge carriers.

The construction of a novel Au nanoparticles loaded In 2 S 3 /In 2 O 3 hybrid microflowers composite was conducted through a well-designed hydrothermal and partial oxidation method and used for NO 2 sensing at room-temperature (RT). The characterization data confirmed the hybrid structures and demonstrated that the ratio of adsorbed oxygen species on the surface increased after partial oxidation. The sensing performance of flexible gas sensors based on In 2 S 3 /In 2 O 3 , In 2 O 3 , Au x In 2 S 3 /In 2 O 3 (x = 0.5, 1 and 2 wt%) were tested and compared at RT. Heterostructure construction and Au NPs loading significantly improved the sensing properties at RT. Peculiarly, the response value of 1 wt% Au NPs loaded In 2 S 3 /In 2 O 3 (Au 1 In 2 S 3 /In 2 O 3 ) sensor for 100 ppm NO 2 at RT was 20.7, which was 9.2 times higher than that of In 2 O 3 sensor. Meanwhile, it also possessed excellent selectivity, fast response/recovery time (12/27 s), good repeatability, long-term and mechanical stability. The outstanding sensing performance for NO 2 at RT mainly associated to the heterojunction between In 2 S 3 and In 2 O 3 and the catalytic effect of Au NPs. Finally, density functional theory (DFT) was used to calculate and analyze the gas adsorption and charger transfer, which related to the enhanced sensing performance.

A novel ternary heterojunction material In 2 O 3 /In 2 S 3 /ZnIn 2 S 4 was synthesized, and a photoelectrochemical sensor was fabricated for the non-invasive test of dopamine (DA) in sweat. In 2 O 3 multihollow microtubules were synthesized and then In 2 S 3 was formed on their surface to construct a type-I heterojunction between In 2 S 3 and In 2 O 3 . ZnIn 2 S 4 was further introduced to form a Z-scheme heterojunction between In 2 S 3 /ZnIn 2 S 4 . Under photoexcitation, the photogenerated holes of In 2 O 3 transferred to the valence band of In 2 S 3 , superimposed with the holes produced by In 2 S 3 , leads to a significantly higher photocatalytic oxidation capacity of In 2 O 3 /In 2 S 3 /ZnIn 2 S 4 ternary composites than that of In 2 O 3 /In 2 S 3 . The Z-scheme heterojunction accelerates the transfer of photogenerated electrons accumulated on the type-I heterojunction. In the presence of DA, it is rapidly oxidized into polydopamine (PDA) by In 2 O 3 /In 2 S 3 , and the benzoquinone groups of PDA compete for the photogenerated electrons to reduce the current in the external circuit, whereby DA determination is achieved. Owing to the combination of type-I and Z-scheme heterojunction, the sensor showed extremely high sensitivity, with a detection limit of 3.94 × 10 −12 mol/L. It is one of the most sensitive methods for DA detection reported and has been applied to the determination of DA in human sweat. Graphical Abstract

Herein, noble-metal-free In 2 S 3 -WC and In 2 S 3 -based photocatalysts with dual cocatalysts of flower-like MoS 2 and bulk WC were synthesized through a facile solvothermal reaction. Electrochemical results indicated WC increased the interface conductance of photocatalyst and boosted the transference of photogenerated carriers. The optimal In 2 S 3 -WC show a hydrogen production rate of 128.11 μmol·h −1 ·g −1 , which is around 6 times higher than In 2 S 3 -1%Pt (20.73 μmol·h −1 ·g −1 ). The above results demonstrate commercial WC has a crucial impact of replacing precious metal and separating carriers. Morphology characterization exhibited hydrangea In 2 S 3 and flower-like MoS 2 were attached to bulk WC. Gratifyingly, photocurrent, impedance and photoluminescence results demonstrated MoS 2 further effectively separated the photogenerated carriers. Remarkably, the higher hydrogen generation rate of 390.52 μmol·h −1 ·g −1 obtained by the optimal ternary In 2 S 3 -WC-MoS 2 composite was around 3 and 18 times higher than the optimal In 2 S 3 -WC and In 2 S 3 -1% Pt. The photocatalytic results demonstrated that "W-Mo auxiliary pairs" was a great efficient synergistic cocatalyst for In 2 S 3 to increase active sites and improve e - -h + pairs separation for H 2 generation. Furthermore, a probable reaction mechanism of the enhanced photocatalytic H 2 generation was also proposed. This presented research provides an effective concept to design novel and efficient noble-metal-free photocatalyst with "W-Mo auxiliary pairs" for prominent H 2 generation activity.

Here, we synthesized a series of noble-metal-free MoP/In 2 S 3 Schottky heterojunction photocatalysts through two-step synthesis. Morphology characterization revealed that In 2 S 3 was deposited on metal-like MoP. The electrochemical experiment, photoluminescence (PL) and time-resolved transient PL results verify that electron-hole pairs separation efficiency of MoP-In 2 S 3 composites has been immensely elevated compared to pristine In 2 S 3 . The effective separation of photocarriers is attributed to the appropriate Schottky energy barrier, band bending and Fermi level rearrangement between MoP and In 2 S 3 . Furthermore, the X-ray photoelectron spectra confirmed that electrons transferred from In 2 S 3 to MoP in Schottky heterojunction. Importantly, MoP possesses active sites for H 2 generation resulting from nearly zero binding for H atoms and low onset overpotentials. As expected, the 25 %MoP-In 2 S 3 composites exhibited excellent photocatalytic activity (481.73 μmol·h −1 ·g −1 ), which was about 23 times than In 2 S 3 -1 %Pt (20.73 μmol·h −1 ·g −1 ). Hence, the enhanced photocatalytic performance was ascribed to not only the formed Schottky heterojunction leading to better charge separation, but also MoP as the active sites accelerated the surface proton reduction reaction. The research furnishes a thought that suitable semiconductors and metal-like were selected to construct high performance and low-cost Schottky heterojunction with efficient charge separation and active sites for resultful photocatalytic H 2 generation.

The creation of a Z-scheme heterojunction is a sophisticated strategy to enhance photocatalytic efficiency. In our study, we synthesized an In 2 S 3 /MnO 2 /BiOCl dual Z-scheme heterostructure by growing BiOCl nanoplates on the sheets of In 2 S 3 nanoflowers, situated on the surface of MnO 2 nanowires. This synthesis involved a combination of hydrothermal and solution combustion methods. Experiments and density functional theory (DFT) calculations demonstrated that the In 2 S 3 /MnO 2 /BiOCl composite exhibited notable photo reduction performance and photocatalytic stability. This was attributed to the pivotal roles of BiOCl and MnO 2 in the composite, acting as auxiliaries to enhance the electronic structure and facilitate the adsorption/activation capacity of CO 2 and H 2 O. The yield rates of CO, CH 4 , and C 2 H 4 over In 2 S 3 /MnO 2 /BiOCl as the catalyst were 3.94, 5.5, and 3.64 times higher than those of pure In 2 S 3 , respectively. Photoelectrochemical analysis revealed that the dual Z-scheme heterostructure, with its oxygen vacancies and large surface area, enhanced CO 2 absorption and active sites on the nanoflower/nanowire intersurfaces. Consequently, the dual Z-scheme charge transfer pathway provided efficient channels for boosting electron transfer and charge separation, resulting in high C 2 H 4 , CH 4 , and CO yields of formed and exihibits an promising photoreduction rate of CO 2 to CO (51.2 µmol/g.h), CH 4 (42.4 µmol/g.h) and C 2 H 4 (63.2 µmol/g.h), respectively. DFT, in situ Diffuse reflectance infrared fourier transform spectroscopy, and temperature-programmed desorption tests were employed to verify the intermediates pathway. The study proposed a potential photocatalytic mechanism based on these findings.

Limited by rapid carrier recombination, the photocatalytic hydrogen peroxide (H 2 O 2 ) generation performance of Zn 2 In 2 S 5 is far from practical application. Herein, Zn 2 In 2 S 5 /In 2 S 3 S-scheme heterostructures were constructed by employing a one-step hydrothermal strategy that precisely adjusted the Zn:In precursor ratio. Thanks to the band structures with sufficiently redox ability of In 2 S 3 and Zn 2 In 2 S 5 , as well as enhanced carrier separation and transfer efficiency, the optimal Zn 2 In 2 S 5 /In 2 S 3 heterostructures (ZIS/In 2 S 3 -1:4) achieved a sacrificial-agent-free H 2 O 2 production rate of 339.5 μM h −1 under AM 1.5 irradiation, which approximately 1.7 times higher than that of pristine Zn 2 In 2 S 5 . Meanwhile, it also exhibited good H 2 O 2 evolution rate under visible-light irradiation and reusability. Its apparent quantum yield (AQY) at 380 nm, 420 nm, and 450 nm reached to 1.32 %, 1.11 %, and 0.63 %, respectively. In addition, the introduction of In 2 S 3 inhibited H 2 O 2 decomposition and enhanced the selectivity of H 2 O 2 production. In the photocatalytic process, superoxide radicals and holes were the key reactive substances, thereby H 2 O 2 was generated via a two-step single-electron O 2 reduction reaction process and one-step two-electron water oxidation reaction process. The construction strategy of the Zn 2 In 2 S 5 /In 2 S 3 S-scheme heterostructures is expected to provide a new perspective for the design of photocatalysts for efficient H 2 O 2 synthesis.
