Room-temperature sodium-sulfur (RT Na-S) batteries have been attracting enormous interests due to their low-cost, high capacity and environmental benignity. However, the shuttle effect and the sluggish electrochemical reaction activity of sodium polysulfides (NaPSs) seriously restrict their practical application. To solve these issues, we rationally designed an advanced Sn-doped In 2 S 3 /S/C cathode for RT Na-S batteries by magnetron sputtering in this work, which exhibited a high reversible capacity (1663.5 mAh g −1 at 0.1 A g −1 ) and excellent cycling performance (902.9 mAh g −1 after 50 cycles). The in situ electrochemical impedance spectroscopy indicated that the Sn-doped In 2 S 3 coating can accelerate charge-transfer kinetics and facilitate the diffusion of Na + . Furthermore, theoretical calculation revealed that doping of Sn into In 2 S 3 can reduce the energy band gap, thus accelerating the electron transfer and promoting the electrochemical conversion of active species. It is demonstrated that adjusting the electronic structure is a reliable method to improve the electrocatalytic effect of catalyst and significantly improve the performance of S cathode in RT Na-S batteries.

Water vapor greatly interferes with gas sensing characteristics of metal oxide semiconductors (MOS). Consequently, for the first time, Nd 2 O 3 -loaded In 2 O 3 porous nanorods were synthesized which exhibited excellent H 2 S sensitivity along with prominent humidity-independent characteristics, whereas pristine In 2 O 3 without Nd 2 O 3 showed deteriorated H 2 S sensing features under increasing ambient humid conditions in a wide operating temperature range. The mechanism of humidity-independent H 2 S sensing properties was researched via X-ray photoelectrons spectroscopy (XPS), in-situ Fourier Transform infrared spectroscopy (in-situ DRIFTS) and the corresponding gas sensing measurements, which is in close relations with the inhibition of chemisorbed oxygen and scavenging hydroxyl groups on In 2 O 3 surface induced by surficial Nd 2 O 3 component. This strategy poses a cutting-edge comprehending of temperature-dependent humidity-interference on MOS, paves a novel route for fabricating H 2 S sensors with exceptional sensitivity, selectivity and anti-humidity properties, which will be quite conducive for real-time exhaled breath analyses in disease diagnosis.

This work reports a gallium indium alloy (EGaIn)-doped SiBOC ceramic that possesses a unique liquid-metal-in-ceramic feature. The low-viscosity liquid nature of gallium-based liquid metals (Ga-LMs) and the reactive core-shell structure provide possibilities for phase engineering inside polymer-derived ceramics. As a demonstration, EGaIn nanoparticles (NPs) are directly mixed with a UV-curable ceramic precursor (UV-PBS) to obtain a resin suitable for digital light processing 3D-printing. After pyrolysis at 800–1200 °C, SiBOC ceramics with uniformly distributed EGaIn NP domains (Si(GaIn)BOC) are obtained. EGaIn plays a key role in promoting carbonization and preventing crack formation during the polymer-to-ceramic process, resulting in an increase in both ceramic yield and mechanical strength. EGaIn NPs are also found to have a core-shell structure (EGaIn@(GaxIn1- x )2O3@SiBOC) inside the SiBOC matrix, which significantly enhances the dielectric properties and improves the interfacial polarization. As a result, an excellent electromagnetic wave absorption performance is achieved across the C, X, and Ku bands, respectively. Through rational design, a novel metastructure design based on the Schwarz P minimal surface is proposed, which exhibits an ultrawide effective absorption band extending up to 11.36 GHz (within C-Ku bands).

Indium oxide (In 2 O 3 ) is a promising semiconductor used for various photocatalytic reactions, yet the green and template-free synthesizing the different micro/nanostructured In 2 O 3 with tunable morphology is still full of challenge. In this study, the three morphological In 2 O 3 with 3D micro-cubelike (In 2 O 3 -MC), 3D micro-ricelike (In 2 O 3 -MR), and 2D nano-platelike (In 2 O 3 -NP) were successfully fabricated through a facile hydrothermal strategy without any organic template additives. Owing to the enlarged specific surface area , promoted charge migration rate and suitable surface oxygen vacancies density, the unique 3D ricelike In 2 O 3 -MR exhibited the best photocatalytic H 2 generation activity from biomass glucose solution, which was 1.9-fold and 1.7-fold higher than that of In 2 O 3 -MC and In 2 O 3 -NP under the same experimental conditions. In addition, the optimum photoactivity of In 2 O 3 -MR was achieved under the alkaline environment with pH = 11 and 1.0 wt% Pt cocatalyst loading, which was better than the most of previously reported In 2 O 3 -based photocatalysts . Simultaneously, the possible photocatalytic mechanism for solar H 2 evolution from glucose solution was also discussed. Our work will bring about potential application in preparation of other photocatalysts with controlling morphology for renewable photocatalysis .

Reasonable design of high-performance catalysts with heterojunction to suppress the combination of electron-hole pairs has become an appealing challenge in photocatalytic field. Herein, a novel hydrangea-like ZnIn 2 S 4 /FePO 4 with S-scheme heterojunction was constructed via an ultrasound-annealing process for photocatalytic H 2 evolution. The composites showed remarkable photocatalytic H 2 production performance (3.337 mmol h −1 g −1 ), which was approximately 7.5 times higher than that of blank ZnIn 2 S 4 (0.446 mmol h −1 g −1 ). The improved photocatalytic H 2 evolution was mainly ascribed to the accelerated electron-hole separation through the construction of S-scheme heterojunction in interface. Moreover, the hydrangea-like structure provided abundant active sites and huge specific surface area, which was conducive to the exceptional photocatalytic activity. Simultaneously, both experimental and Density Functional Theoretical calculation results provided strong evidence for the transfer path of photogenerated carriers following the S-scheme heterojunction, and the unique mechanism of photocatalytic H 2 production was proposed. In addition, the hydrangea-like ZnIn 2 S 4 /FePO 4 heterojunction photocatalyst showed a commendable stability with no distinct decrease after three cycle tests, demonstrating its potential as a recoverable photocatalyst. This work offered insights into the design and preparation of highly efficient photocatalysts with S-scheme heterojunction.

A series of BiVO 4 /InVO 4 composites were synthesized by one-pot microwave method based on the ratio regulation of Bi/In. Consequently, the as-fabricated BiVO 4 /InVO 4 photocatalysts performed higher photocatalytic activities (100%) than pure InVO 4 and BiVO 4 . The prepared photocatalysts were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), UV–vis diffuse reflection spectroscopy (UV–vis DRS) and Fourier transform infrared spectra (FTIR). The results indicate the formation of BiVO 4 /InVO 4 and it possesses enhanced solar light absorption. The enhanced reduction rate is ascribed to the efficient separation of photogenerated charge carriers due to the heterojunction formed between BiVO 4 and InVO 4 . The possible photocatalytic mechanism of BiVO 4 /InVO 4 composite was also discussed in detail.

Metal selenides are considered as a group of promising candidates as the anode material for sodium-ion batteries due to their high theoretical capacity. However, the intrinsically low electrical and ionic conductivities as well as huge volume change during the charge-discharge process give rise to an inferior sodium storage capability, which severely hinders their practical application. Herein, we fabricated In2Se3/CoSe2 hollow nanorods composed of In2Se3/CoIn2/CoSe2 by growing cobalt-based zeolitic imidazolate framework ZIF-67 on the surface of indium-based metal–organic framework MIL-68, followed by in situ gaseous selenization. Because of the CoIn2 alloy phase in between In2Se3 and CoSe2, a heterostructure consisting of two alloy/selenide interfaces has been successfully constructed, offering synergistically enhanced electrical conductivity, Na diffusion process, and structural stability, in comparison to the single CoIn2-free interface with only two metal selenides. As expected, this nanoconstruction delivers a high reversible capacity of 297.5 and 205.5 mAh g–1 at 5 and 10 A g–1 after 2000 cycles, respectively, and a superior rate performance of 371.6 mAh g–1 at even 20 A g–1.

In this work, a series of In(OH) 3 with abundant indium vacancies were synthesized by hydrothermal method using mixed solvent of ethylenediamine(En) and water for photocatalytic reduction of CO 2 with H 2 O vapor. The morphology, particle size, crystallinity, pore structure, and vacancy concentration of photocatalysts were successfully regulated by adjusting the ratio of En and water in mixed solvent, which were characterized by XRD, FT-IR, TG-DTA, SEM, HRTEM, UV–vis DRS, PL spectra, XPS, and EPR. Moreover, the effect of En/water ratio on the adsorption capacity to CO 2 and photo-electrical properties of In(OH) 3 were further investigated by in-situ FTIR, PL spectra, UV–vis DRS, CV, and EIS. In(OH) 3 prepared in mixed solution exhibited much higher photocatalytic activity for CO 2 reduction with H 2 O vapor compared to that prepared with water only solvent. The enhanced photocatalytic performance can be attributed to the special morphology, smaller particle size, larger BET surface area, and especially generated indium vacancies creating defect energy levels in the bandgap, which improved visible light absorption, carrier separation, and CO 2 chemisorption. This work paves the way to enable a non-visible-light response material with high visible-light photocatalytic activity by regulating vacancy concentration via a facile method.

Photocatalytic hydrogen (H2) production coupled with selective oxidation of organic compounds into high-value-added organic intermediates has expansive prospects in the utilization and transformation of solar energy, which meets the development requirements of green chemistry. In this work, high-efficiency hole cocatalyst PdS-decorated In2S3 flower-like microspheres are fabricated for the effective visible-light-driven C–N coupling of amines to imines coupled with H2 evolution. Owing to the establishment of the internal electric field, which further boosts the transfer of photoexcited holes to PdS, PdS–In2S3 exhibits distinctly enhanced photocatalytic redox performance, which is 39.8 times higher for H2 and 14.3 times higher for N-benzylidenebenzylamine than that of the blank In2S3, along with high selectivity and stability. Furthermore, the practicability of dehydrogenation coupling of various aromatic amines to the corresponding C–N coupling products on PdS–In2S3 has been demonstrated and a plausible reaction mechanism has been proposed. This work is anticipated to stimulate further interest in establishing an innovative photoredox platform for selective organic synthesis coupled with H2 evolution in a green and sustainable way.

Two dimensional (2D) tin disulfide (SnS2) has attracted growing interest as a promising high performance photodetector with superior performance such as fast response time, high responsivity, and good stability. However, SnS2-based photodetectors still face great challenges, and the photodetection performance needs to be improved for practical applications. Herein, indium-doped SnS2 (In-SnS2) few layers were exfoliated from CVT-grown single crystals, which were synthesized by chemical vapor transport. Photodetectors based on In-SnS2 few layers were fabricated and detected. Compared with photodetectors based on pristine SnS2, photodetectors based on In-SnS2 few layers exhibited better photodetection performances, including higher responsivities, higher external quantum efficiencies, and greater normalized detectivities. The responsivity (R), external quantum efficiency (EQE), and normalized detectivity (D*) were increased by up to 2 orders of magnitude after In doping. Considering responsivity and response time, the photodetector based on 1.4 at. % In-SnS2 few layers exhibited an optimal photodetection performance with a high R of 153.8 A/W, a high EQE of 4.72 × 104 %, a great D* of 5.81 × 1012 Jones, and a short response time of 13 ms. Our work provides an efficient path to enhance photodetection performances of photodetectors based on SnS2 for future high-performance optoelectronic applications.

An atomically dispersed structure is attractive for electrochemically converting carbon dioxide (CO2) to fuels and feedstock due to its unique properties and activity. Most single-atom electrocatalysts are reported to reduce CO2 to carbon monoxide (CO). Herein, we develop atomically dispersed indium (In) on a nitrogen-doped carbon skeleton (In–N–C) as an efficient catalyst to produce formic acid/formate in aqueous media, reaching a turnover frequency as high as 26771 h–1 at −0.99 V relative to a reversible hydrogen electrode (RHE). Electrochemical measurements show that trace amounts of In loaded on the carbon matrix significantly improve the electrocatalytic behavior for the CO2 reduction reaction, outperforming conventional metallic In catalysts. Further experiments and density functional theory (DFT) calculations reveal that the formation of intermediate *OCHO on isolated In sites plays a pivotal role in the efficiency of the CO2-to-formate process, which has a lower energy barrier than that on metallic In.

In this paper, gallium-doped indium oxide (In2O3) compounds with different doping amounts were fabricated through the hydrothermal method and the Spark Plasma Sintering process. X-ray diffraction showed that Ga was efficiently doped into the In2O3 lattice. The electrical conductivity is significantly improved by Ga doping, which is due to the reduced potential barrier of the carriers for the transition to the conduction band. The carrier concentration of Ga-doped In2O3 reaches 1.11 × 1020 cm–3, which is 12 times that of pristine In2O3, and the electrical conductivity (6.79 × 104 S m–1) is 5 times that of pristine In2O3. Furthermore, the lattice distortion in the doped sample acts as strong phonon scattering centers, which effectively reduce the mean free path of the phonons, resulting in a significant decrease in the lattice thermal conductivity. Finally, at 873 K, the zT value of In1.88Ga0.12O3 reaches 0.22, which shows a 100% increase compared with that of the pure In2O3 sample. Our results show that the control of metal doping and microstructure can achieve synergistic optimization of the electrical properties and thermal conductivity of In2O3, providing a reference for other thermoelectric materials.
