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.

The development of highly active and stable photocatalysts, an effective way to remediate environment pollution and alleviate energy shortages, remains a challenging issue. In this work, a CdIn2S4/In(OH)3nanocomposite was deposited in-situ on NiCr-LDH nanosheets by a simple hydrothermal method, and the obtained CdIn2S4/In(OH)3/NiCr-LDH heterostructure photocatalysts with multiple intimate-contact interfaces exhibited better photocatalytic activity. The photocatalytic H2evolution rate of CdIn2S4/In(OH)3/NiCr-LDH increased to 10.9 and 58.7 times that of the counterparts CdIn2S4and NiCr-LDH, respectively. Moreover, the photocatalytic removal efficiency of Cr(VI) increased from 6% for NiCr-LDH and 75% for CdIn2S4to 97% for CdIn2S4/In(OH)3/NiCr-LDH. The enhanced photocatalytic performance was attributed to the formation of multi-interfaces with strong interfacial interactions and staggered band alignments, which offered multiple pathways for carrier migration, thus promoting the separation efficiency of photo-excited electrons and holes. This study demonstrates a facile method to fabricate inexpensive and efficient heterostructure photocatalysts for solving environmental problems.

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

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 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.

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.

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.

An intervening barrier for photocatalytic water decomposition and pollutant degradation is the frustratingly quick recombination of e − - h + pairs. Delicate design of heterojunction photocatalysts by coupling the semiconductors at nanoscale with well-matched geometrical and electronic alignments is an effective strategy to ameliorate the charge separation. Here a facile and environment-friendly l -cysteine-assisted hydrothermal process under weakly alkaline conditions is demonstrated for the first time to fabricate ZnIn 2 S 4 /In(OH) 3 hollow microspheres with intimate contact, which are verified by XRD, SEM, (HR)TEM, XPS , N 2 adsorption-desorption, UV–Vis DRS and photoluminescence spectra. ZnIn 2 S 4 /In(OH) 3 heterostructure (L-cys/Zn 2+ = 4, molar ratio) with a band-gap of 2.50 eV, demonstrates the best photocatalytic performance for water reduction and MB degradation under visible light, outperforming its counterparts (In(OH) 3 and ZnIn 2 S 4 ). The excellent activity of ZnIn 2 S 4 /In(OH) 3 heterostructure arises from the intercrossed band-edge positions as well as the unique hollow structure with large surface area and wide pore-size distribution, which are beneficial for the efficient charge migration from bulk to surface as well as at the interface between ZnIn 2 S 4 and In(OH) 3 . This work provides an efficient and eco-friendly strategy for one-pot synthesis of heterostructured composites with intimate contact for photocatalytic application.

The convenient modification of transition metal and the simultaneous adjustment of energy band are effective measures to improve the photocatalytic activity of titanium dioxide but remains challenging in photocatalytic hydrogen evolution field. Herein, In(OH) 3 -TiO 2 heterostructures were constructed by solid-state synthetic strategy under room temperature for tuning the band structure and accelerating the photoexcited charge separation to enhance the photocatalytic activity for hydrogen evolution. By the quantified modification of In(OH) 3 , the obtained In(OH) 3 -TiO 2 delivers an appreciable photocatalytic activity and stability for hydrogen evolution, which is 15.7 folds superior to commercial P25. Due to the narrowed band gap, the increased charge carrier density, the restrained recombination rate of photoexcited electron-hole pairs and the accelerated photogenerated charge separation, the In(OH) 3 -TiO 2 heterostructures thereby achieve the boosted photocatalytic hydrogen evolution performance. This work provides a feasible strategy to enhance the photocatalytic hydrogen evolution of TiO 2 via tuning the band gap and accelerating the photoinduced charge separation.

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.

Nitrogen dioxide (NO2), the main component of pollutants in atmospheric environments, causes and exacerbates respiratory diseases, especially during outdoor sports even at the 100 ppb level. Currently, environmental gas detection still faces challenges such as high detection limits, low SNR, and low sensitivity. A NO2 sensor based on In(OH)3-α-Fe2O3–ZnO was prepared using a hydrothermal method, featuring an ultralow detection limit of 82 ppt, an exceptionally high SNR of 574,000, and an ultrahigh sensitivity of 252.25 mV/ppm (100 ppb to 1 ppm). And this sensor exhibits excellent response, selectivity, and repeatability. These excellent sensing characteristics come from the adsorbed oxygen on the surface of the material with the formation of n–n heterojunctions. Additionally, a low-power, portable, and cost-effective environmental monitoring system (named Smart Breath Sentinel (SBS)) was designed to intelligently upgrade ordinary masks. SBS enables real-time wireless environmental gas monitoring with integrated humidity compensation to ensure accurate measurements in high-humidity environments. SBS has already been tested in multiple environments, and the test results have proven the feasibility of SBS. This sensor based on In(OH)3-α-Fe2O3–ZnO demonstrates significant potential for applications aimed at enhancing human safety.

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 .
