Acetone, a critical biomarker in exhaled breath for the diagnosis of diabetes, necessitates the development of high-performance gas sensors for real-time monitoring. In this work, bimetallic In 2 O 3 /Co 3 O 4 porous nanorods with tunable In/Co molar ratios were synthesized via a hydrothermal approach. The optimized sensor 3-ICO (In:Co = 3:10, molar ratio), exhibited remarkable acetone-sensing performance with a high response of 125.6 to 10 ppm acetone at 250 °C, ultrafast response/recovery times (45 s/19 s), outstanding selectivity, and long-term stability. The integration of materials characterization with density functional theory (DFT) simulations demonstrated that the p-n heterojunction formed between Co 3 O 4 and In 2 O 3 facilitates interfacial charge transfer, enhancing both the oxygen vacancy concentration and specific surface area. These synergistic effects significantly improve acetone adsorption energy and electron transport efficiency. This work highlights the pivotal role of heterojunction engineering in optimizing the detection performance of metal-oxide semiconductors for low-concentration volatile organic compounds (VOCs), offering promising applications in non-invasive diabetes diagnosis.

Novel TiO 2 –In 2 O 3 @g–C 3 N 4 hybrid system was synthesized by a facile solvothermal method. The photocatalytic activity of the TiO 2 –In 2 O 3 @g–C 3 N 4 hybrid material was evaluated via degradation of RhB and hydrogen-production. It could be found that TiO 2 –In 2 O 3 @g–C 3 N 4 ternary composites exhibit the highest RhB degradation rate, which was 6.6 times than that of pure g–C 3 N 4 . As expected, the H 2 -generation rate of the as-prepared ternary materials was found to increase by 48 times than that of pure g–C 3 N 4 . The enhanced activities were mainly attributed to the interfacial transfer of photogenerated electrons and holes among TiO 2 , In 2 O 3 and g–C 3 N 4 , leading to the effective charge separation on these semiconductors, which were evidenced by photoluminescence spectroscopy, electrochemical impedance spectroscopy and photocurrent analysis. The photocatalytic mechanism and photostability of the ternary hybrid materials were also proposed. This work may provide a stepping stone towards the design and practical application of multifunctional hybrids photocatalysts in the photocatalytic degradation of pollutions and hydrogen generation.

The engineering of photocatalysts with hollow structures is essential for improving the absorption of visible-light irradiation to boost the photocatalytic activity of organic contaminants. This study presents a feasible cavity engineering method for the synthesis of nitrogen-doped In 2 O 3 @carbon spherical structures produced from In-MOF. These spherical structures feature a well-defined central void, achieved through CTAB-assisted aggregation of In 2 O 3 via annealing In-MOF in an air atmosphere. The N-doped In 2 O 3 @carbon photocatalysts were employed for the degradation of tetracycline hydrochloride (TCH) under visible-light irradiations. The optimized N-doped In 2 O 3 @carbon catalyst (In 2 O 3 -III) exhibited 98 % degradation of tetracycline hydrochloride within 60 min of visible-light irradiation. Hollow cavity engineering may offer several active sites, a reduced band gap, and considerable benefits for the separation of electron-hole (e − /h + ) pairs and light absorption capability. Furthermore, the presence of an optimal concentration of nitrogen and oxygen vacancies in the In 2 O 3 -III synergistically contributed to the improved visible light-driven photocatalytic degradation of tetracycline hydrochloride. Several parameters influencing the mineralization of TCH were examined, comprising catalyst type, TCH concentration, initial solution pH, catalyst dosage, inorganic anions, and radical species. Radical capturing tests and electron spin resonance studies indicate that h + and O 2 •- were the principal species engaged in the degradation of TCH.

Continuous and reliable monitoring of ammonia (NH 3 ) biomarkers in exhaled breath holds critical significance for the diagnosis of kidney diseases. However, existing NH 3 sensors often suffer from interference by ambient water molecules, limiting their applications in monitoring exhaled breath with high humidity. In this work, a water-vapor-assisted sensing mechanism is proposed, and a humidity-enhanced flexible NH 3 sensor capable of detecting NH 3 at concentrations as low as 250 ppb in exhaled breath is developed. By integrating hydrothermally synthesized indium oxide (In 2 O 3 ) nanoparticles with delaminated monolayer MXene (Ti 3 C 2 ) nanosheets, a stable heterojunction structure is constructed, which underpins the sensor's performance. Through a streamlined integration strategy, the MXene/In 2 O 3 composite is combined with cotton fibers to fabricate a flexible and wearable NH 3 sensor. This device demonstrates superior gas-sensing characteristics under ambient temperature and high-humidity conditions, yielding a response of 70.64% and a response time of 178 s. Furthermore, the flexible sensor is embedded into a KN95 mask to develop an intelligent breath analysis system. By applying machine learning algorithms to model and classify breath samples, a detection accuracy of 94% in real-world clinical testing is achieved. These results underscore the sensor's substantial potential for non-invasive early screening and home-based diagnosis of kidney diseases.

The chemical interaction between the target gas and adsorbed oxygen species is a critical factor significantly influencing the sensing performance of metal oxide semiconductor (MOS)-based gas sensors. Thus, we propose a design strategy: improving sensing performance by incorporating materials with exceptional catalytic properties into MOS-based sensing materials. High-entropy oxides (HEOs) demonstrate exceptional catalytic activity attributed to the synergistic effects among their constituent elements and have been the focus within catalysis. Accordingly, we proposed preparing HEOs/In 2 O 3 composite nanofibers with varying HEOs loadings via electrospinning. The micro/nanostructure, elemental composition, oxygen vacancies, and other physicochemical properties were characterized. Compared with pure In 2 O 3 sensors, the load of HEOs improved the response value and reduced response time. Especially, the sensor utilizing In 2 O 3 nanofibers loaded with the optimal amount of HEOs exhibited the highest response to 1 ppm H 2 S at 180 °C, capable of detecting concentrations as low as 100 ppb. Furthermore, this sensor exhibited outstanding selectivity and good long-term stability. The changes in physicochemical properties of In 2 O 3 nanofibers, including the surface oxygen vacancy content, acidity/alkalinity and surface catalytic activity, which were induced by the load of HEOs, are the crucial factors underlying the improvement of the sensor's performance in H 2 S detection. These results provide an excellent theoretical reference for the design of MOS-based sensitive materials to detect H 2 S gas.

Au nanoparticle (NP)- and CdS quantum dot (QD)-codecorated In2O3 nanosheets, assembled into flowerlike structure (In2O3/Au/CdS), were synthesized to facilitate photocatalytic H2 production. The optimized In2O3/Au4/CdS-12 (4 wt % Au NPs and CdS QDs were deposited for 12 cycles) displays achieved a photocatalytic hydrogen generation ability of 17.23 μmol/h (10 mg of catalyst), which is 22.97, 5.08, and 5.05 times as high as that of pristine In2O3 (0.75 μmol/h), In2O3/Au4 (3.39 μmol/h), and In2O3/CdS-12 (3.41 μmol/h), respectively. This significant improvement of H2 generation rate can be attributed to the following factors: the heterojunction at the In2O3–CdS interface and the Schottky barrier at the interface between In2O3–Au and CdS–Au improves the migration and separation of charge carriers, and the surface plasma resonance (SPR) effect of noble metal Au NPs enhances the light harvesting capacity of In2O3 and boosts the generation of hot electrons, efficiently improving the utilization rate of sunlight.

Silicon (Si) shows excellent potential as an anode material for sulfide-based all-solid-state lithium batteries (ASSLBs). However, Si anodes face inherent challenges such as low electron conductivity and large volume changes during cycling, ultimately resulting in a short cycle life. Herein, to address these challenges, In 2 O 3 /C derived from an indium-based metal-organic framework (In-MOF) is utilized to encapsulate Si particles in situ. The Li-In alloy and Li 2 O formed in situ after the lithiation of In 2 O 3 /C provide rapid Li + transportation properties, and the existence of In 2 O 3 /C efficiently relieves the significant volume changes of Si. Consequently, the Si anode exhibits improved cyclic stability. The composite Si@In 2 O 3 /C anode prepared with a high loading of 7.64 mg cm −2 maintains a high specific capacity of 1093.2 mAh g −1 (8.36 mAh cm −2 ) after 500 cycles at 2.74 mA cm −2 , maintaining 84.3% of the initial capacity. Furthermore, a full cell prepared with a Si@In 2 O 3 /C composite anode and a LiNbO 3 -coated LiNi 0.7 Co 0.2 Mn 0.1 O 2 (LNO@NCM) cathode shows excellent cyclic stability, with 74.3% of the capacity retained after cycling 1000 times at 0.2C (0.51 mA cm −2 ) and an average Coulomb efficiency of 99.94%. This study offers a compelling idea for the design of sulfide-based ASSLB anode materials.

Defect sites in heterostructures play a vital role in optimizing interfacial charge separation efficiency and carrier migration behavior, which enhance surface reaction dynamics. However, the effect of defect sites on modulation of electronic structure and oxygen activation is still ambiguous. Herein, we successfully construct in-plane ZnIn 2 S 4 /In 2 O 3 heterostructures by partial in-situ oxidation strategy and the surface properties can be precisely tuned by treating at individual temperatures. Notably, the in-plane ZnIn 2 S 4 /In 2 O 3 heterostructure which is treated in air at 425 °C exhibits outstanding sensing performance towards acetoin (R a /R g = 248.6 for 50 ppm acetoin at 180 °C), a biomarker of Listeria monocytogenes, with rapid response and recovery dynamic (18/183 s), along with excellent reliability and sensing stability. Detailed characterization and DFT calculation indicate that in-plane heterostructures possess numerous grain boundaries, thereby modulating the p-orbitals electronic structure of oxygen atom and promoting the formation of reactive oxygen species (O − (ad)). Moreover, the built-in electric field further also facilitates the electron transfer, further contributing to the enhanced sensing performance for 3-hydroxy-2-butanone.

Chlorpyrifos (CPF) is widely utilized in agricultural practices, and its residue in food raise significant concerns food safety. However, current detection methods often suffer from complex operation procedures and unstable signal responses. Therefore, there is an urgent need to develop a reliable sensor for detecting CPF residue in food samples. In this work, a Z-scheme heterojunction was formed using hollow In 2 O 3 (H-In 2 O 3 ) and Bi 2 WO 6 nanosheets. The staggered band structure of the H-In 2 O 3 /Bi 2 WO 6 heterojunction facilitates carrier separation and transfer, thereby enhancing the sensor's response. In the presence of CPF, it reacts with · OH radicals generated by the heterojunction, further amplifying the signal. The sensor exhibits a linear response in the range of 5–700 nM with a limit of detection (LOD) of 0.72 nM. In addition, this photoelectrochemical sensor demonstrates satisfactory stability, anti-interference, selectivity and reproducibility, showing great potential for CPF analysis in real samples.

The synthesis of a novel In 2 O 3 /In 2 S 3 microsphere heterostructures is conducted through a well-designed two-step hydrothermal method. These composites are first applied for efficient fixation of N 2 to NH 3 under mild conditions without any organic scavengers and precious-metal cocatalysts. Here the In 2 S 3 flakes are in situ generated and uniformly assembled on In 2 O 3 microsphere. The phase structures, morphologies and oxygen vacancies of the samples are systematically characterized by X-ray powder diffraction (XRD), field-emission scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), UV–vis diffuse-reflectance spectroscopy (DRS), and photoluminescence spectroscopy (PL), Raman, electron spin resonance (ESR) spectroscopy and photoelectrochemistry. Meanwhile, the investigation of photocatalytic performance can confirm that the nitrogen fixation rate of In 2 O 3 /In 2 S 3 (III) heterostructure is 40.04 μmol g −1 h −1 , which is about 4.7 and 6.0 times higher than that of pure In 2 O 3 and In 2 S 3 , respectively.

The present study developed bifunctional catalyst for CO 2 hydrogenation into dimethyl ether (DME), whereby it consists of Pd/In 2 O 3 for CO 2 hydrogenation into methanol, and H-ZSM-5 for methanol dehydration into DME. The catalyst development was focused on the synthesis of Pd/In 2 O 3 via a green and low-cost synthesis method of carbonized alginate templating. Thus, microspherical-confined nano-Pd/In 2 O 3 was formed, whereby the localized nucleation growth was coordinated by the chemically entrapped In 3+ via ionic bond in the well-distributed alginate structure. It was found that hydrothermal temperature plays a key role in the development of this catalyst structure. The optimum hydrothermal temperature is 160 °C, as it is able to produce the highest amount of methanol. This catalyst was further integrated with H-ZSM-5 via different integration manners. It was found that mortar mixed method produces the highest amount of DME, as the close proximity causes stronger ion-exchange mechanism between the catalyst components, which facilitates higher oxygen vacancy density in the bifunctional catalyst. Under the optimum Pd/In 2 O 3 : H-ZSM-5 (PdIn-160–12: H-ZSM-5) mass ratio of 4:1, the highest STY DME of 79.7 g DME kg cat -1 h −1 with CO 2 conversion of 9% and DME selectivity of 44.1% can be achieved. In addition, the STY DME can be maintained even in 60 h on stream, demonstrating the excellent stability and performance of microspherical-confined nano-Pd/In 2 O 3 /H-ZSM-5 bifunctional catalyst synthesized via carbonized alginate templating strategy.

A strategy of tuning the size of In 2 O 3 nanocube was employed to change the surface property of g–C 3 N 4 –In 2 O 3 heterojunction to boost its photocatalytic H 2 production. In the type II g–C 3 N 4 –In 2 O 3 heterojunction, the change on the size of In 2 O 3 nanocube (30, 60 and 120 nm) could regulate visible light utilization ability and photoelectric conversion efficiency of photogenerated charge carriers. The directional transfer of charge carriers caused the accumulation of photoexcited electron in plasmonic In 2 O 3 and localized electric field enhancement. The intensity and spatial distribution of localized electric field could be tuned by the adjustable size of In 2 O 3 nanocube. Therefore, the obtained g–C 3 N 4 –In 2 O 3 heterojunction with an optimal size of In 2 O 3 nanocube (60 nm) exhibited supreme photocatalytic H 2 evolution rate of 3.1 mmol h −1 g −1 with a high apparent quantum efficiency of 5.27%, which was 7.5 times higher than that of bare g-C 3 N 4 nanosheet (0.4 mmol h −1 g −1 ).
