Electroreduction of CO 2 for formic acid production has been regarded as an efficient option for CO 2 utilization. However, under high current, achieving high selectivity for formic acid is challenging, which cannot meet industrial demands. Herein, we reported a type of Bi/In(OH) 3 (BIO) heterojunction reconstructed from Bi 2 S 3 /In(OH) 3 during electrochemical process, in which In(OH) 3 was applied to modulate the electronic structure of Bi. This strategy efficiently enhanced the ∗OCHO intermediates adsorption and lead to a decent selectivity towards formic acid under high current density. BIO displays faraday efficiency of formic acid beyond 95 % across a wide range current density of 200–400 mA cm −2 , where the highest value reached 97.7 % at 400 mA cm −2 . This work clarified the mechanism of CO 2 electroreduction to HCOOH on heterojunction, guiding the design of advanced catalysts.

Industrialization and agricultural demand have both improved human life and led to environmental contamination. Especially the discharge of a lot of poisonous and harmful gases, including ammonia, ammonia pollution has become a pressing problem. High concentrations of ammonia can pose significant threats to both the environment and human health. Therefore, accurate monitoring and detection of ammonia gas are crucial. To address this challenge, we have developed an ammonia gas sensor using In(OH) 3 /Ti 3 C 2 T x nanocomposites through an in-situ electrostatic self-assembly process. This sensor was thoroughly characterized using advanced techniques like XRD, XPS, BET, and TEM. In our tests, the I/M-2 sensor exhibited remarkable performance, achieving a 16.8% response to 100 ppm NH 3 at room temperature, which is a 3.5-fold improvement over the pure Ti 3 C 2 T x MXene sensor. Moreover, it provides swift response time (20 s), high response to low NH 3 concentrations (≤ 10 ppm), and excellent long-term stability (30 days). These exceptional characteristics indicate the immense potential of our In(OH) 3 /Ti 3 C 2 T x gas sensor in ammonia detection. Graphical Abstract

Foreigner element doping is one of effective strategies to promote photocatalytic reaction. Herein, a convenient one-step solvothermal method is applied to enable the isomorphic substitution of In 3+ in In(OH) 3 by Bi 3+ . The composition and microstructure of the photocatalysts were mainly obtained by X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM). UV–Vis diffuse reflectance and photoluminescence (PL) spectroscopy revealed the optical properties of photocatalysts. The surface properties of photocatalysts were mainly characterized by X-ray photoelectron spectroscopy (XPS). Theoretical calculations were used to reveal the reaction mechanism. The results indicated that CO production rate and selectivity of Bi 3+ doped In(OH) 3 are much higher than that of the pure In(OH) 3 , which could be attributed to the extended solar spectral response, the enhanced CO 2 adsorption capacity and the accelerated photogenerated carriers separation. The current work verifies the potential application of isomorphic substitution as an efficient route for solar fuel production.

Very efficient and low-cost photocatalysts containing Indium hydroxide (In(OH) 3 ) anchored on zinc oxide (ZnO) with various morphologies (e.g., hexagonal, pyramids, elliptic, etc.) were synthesized using a hydrothermal approach. The strong interaction between In(OH) 3 and ZnO was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), N 2 adsorption-desorption, UV–vis diffuse reflectance spectroscopy (UV–vis DRS), and X-ray photoelectron spectroscopy (XPS). In(OH) 3 particles grew directly on the ZnO surface and strongly interacted with it, which contributed to the excellent photocatalytic performance of ZnO. A possible formation mechanism of the In(OH) 3 /ZnO nanostructures was proposed. Experiments on photodegradation of methylene blue (MB) showed that the photocatalytic activity of the In(OH) 3 /ZnO nanocomposites correlated with the material morphology. The highest MB removal efficiency by the In(OH) 3 /ZnO hybrid photocatalysts was 90.5% after 120 min exposure to the visible light. The significant improvement of photocatalytic activity of In(OH) 3 /ZnO hybrid can be attributed to their special structural features, which allowed for an extended spectral response as well as for enhanced separation of photogenerated charge carriers. The design principles of this hybrid material apply to other metal-oxide systems to widen variety of advanced material systems with multifunctional properties useful for sensing and other advanced applications.

With the advancement of automotive intelligence and electrification, ethylene glycol (EG), as a critical component in antifreeze and coolant systems, has gained increasing industrial significance. However, the volatile nature of EG poses potential health hazards, making the development of high-performance EG gas sensors an urgent priority. In this study, a CuO-In(OH) 3 Type II p-n heterojunction was directly fabricated through a solvothermal method followed by 200°C annealing. The developed CuO-In(OH)₃-based gas sensor demonstrates exceptional EG sensing performance, exhibiting a response magnitude of 21.3 toward 50 ppm EG at 95°C – 7.9 times higher than that of pure CuO (2.7). Notably, the operating temperature was reduced from 120°C (pristine CuO) to 95°C while maintaining excellent repeatability (6 cyclic tests) and long-term stability (26-day continuous operation). The first engineered heterojunction, characterized by its nanoflower-cube hierarchical architecture, not only provides a novel strategy for designing efficient EG gas sensors but also demonstrates promising potential in environmental safety assurance.

In this study, In(OH)3 nanocrystals with three morphologies including rods, cubes and spheres were synthesized through a hydrothermal method. The morphology and crystalline were manipulated by controlling the growth speed and the addition of ascorbic acid. The InVO4
nanocrystals were obtained by a process sacrificing In(OH)3 templates. The phase transformation of rods and cubes generated size-controllable products, whereas that of nanospheres formed hollow micro-spheres. InVO4 nanocrystals display a brilliant yellow emission band
with the peak at 517 nm. Intriguingly, luminescent rare-earth Eu ions with red emission could be doped into InVO4 nanocrystals during the phase transformation. Excitation and the emission spectra indicated an excitation energy transfer from the vanadate to the rare-earth ions.

A series of the In(OH) 3 species modified ZnS (ZnS–In(OH) 3 X% (X = 2, 5, 7, 10)) photocatalysts were synthesized by a hydrothermal method . ZnS–In(OH) 3 X% (X = 2, 5, 7, 10) exhibited the improvement of photocatalytic activity for the photoreduction of CO 2 into CO compared with ZnS. Characterized by X-ray diffraction (XRD), fourier transforms infrared spectra (FT-IR), high resolution transmission electron microscope (HRTEM), X-ray photoelectron spectroscopy (XPS) valence band spectra, UV–vis diffuse reflectance spectra, photoluminescence (PL) and time-resolved PL decay curves, the crystal structure, band structure and behaviors of photogenerated charge carriers for photocatalyst were explored up. It was revealed that the modification of In(OH) 3 surface species on surface of ZnS can prolong the fluorescence lifetimes of photogenerated charge carriers, enhance the separate of photoinduced charge carriers efficiently and promote better matching between the band structure and the redox potential of the CO 2 /CO, resulting in improvement of photocatalytic activity efficiently for ZnS–In(OH) 3 X% (X = 2, 5, 7, 10) photocatalysts . This work may offer a new understanding to study the effect of surface species modification on photocatalytic performance of photocatalyst.

As a member of the ternary sulfides, CdIn2S4 is a visible light responded catalyst with a band gap of 2.2–2.6 eV, which is suitable for solar spectrum. In this study, a simple two-step solvothermal method was used to construct Ni12P5/In(OH)3/CdIn2S4 composite catalysts with type-II and Z-scheme heterojunctions, and there was a synergy between the two heterojunctions. The Ni12P5/In(OH)3/CdIn2S4 composite catalyst formed a donor-mediator-acceptor system for photogenerated electrons, which greatly improved the separation efficiency of the photogenerated carriers. Moreover, the highest hydrogen production activity achieved by the Ni12P5/In(OH)3/CdIn2S4 composites was 5.75 mmol g−1 h−1, which was 21 times the original CdIn2S4.

The In 2.77 S 4 microspheres had been firstly fabricated by using polyethylene glycol (PEG) as the morphological modifier and then used to hybridize with In(OH) 3 nanocubes by a simply depositional method. The structure, optical properties, morphology, chemical compositions, and charge carrier behaviors of the as-prepared In 2.77 S 4 /In(OH) 3 composites were characterized, respectively. The methyl orange, tetracycline, rhodamine B, and Cr(VI) dilute solution were selected to evaluate their photocatalytic activities. Experimental results showed that In(OH) 3 nanocubes could improve the photocatalytic activity and recyclability of the In 2.77 S 4 microspheres under the visible light irradiation. With the usage of In(OH) 3 increased, the photocatalytic efficiency of the hybrids was firstly increased and then decreased. When the mass ratios of In 2.77 S 4 to In(OH) 3 were 6:2, it reached the maximum of 100% in 15 min for methyl orange, obviously higher than 67.4% of In 2.77 S 4 and 1.1% of In(OH) 3 . Meanwhile, it could also oxidize 85.6% of tetracycline in 20 min, 97.8% of rhodamine B in 7.5 min, and reduce 92.9% of Cr(VI) in 30 min under the visible light irradiation. Moreover, it could still degrade 91.7% of methyl orange solution after 3 cycles, which was much higher than 40.7% of In 2.77 S 4 microspheres. In addition, the possible mechanism of enhancing photocatalytic properties was proposed.

An In(OH)3–PDMS sponge has been synthesized by covalent modification of PDA. The sponge can switch surface wettability reversibly between superhydrophobicity and superhydrophilicity when detecting ammonia. The water contact angle changes from 141.5° to 0° after storage in an ammonia atmosphere, which means an ammonia responsive surface wettability switch. The minimum NH3·H2O concentration that the In(OH)3–PDMS can detected is 5% in 2 h. This kind of quick and sensitive ammonia detector is promising simply by virtue of the surface wettability conversion.

The photocatalytic generation of hydrogen peroxide (H 2 O 2 ) using artificial synthetic methods is promising. However, the sluggish hole-induced water oxidation half-reaction that hinders charge separation severely limits H 2 O 2 generation efficiency. This study used the oxidation half-reaction of tetracycline (C 22 H 24 N 2 O 8 , TC) to accelerate charge separation over GaOOH/In(OH) 3 composites with Type II heterojunctions under sunlight irradiation to increase the H 2 O 2 generation efficiency. The results demonstrated that the H 2 O 2 generation efficiency significantly increased from 74.7 to 389.8 µmol L −1 h −1 as the TC degradation efficiency increased from 0.02 to 0.37 mg L −1 h −1 . Radical quenching experiments further indicated that TC degradation consumed holes, increasing the electron formation rate and enhancing H 2 O 2 generation. A comparison with density functional theory calculations revealed that H 2 O 2 generation was a one-step 2-electron route (O 2 + 2e − + 2H + → H 2 O 2 ). These findings are expected to provide new strategies for promoting photocatalytic synthesis of H 2 O 2 .

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.
