Graphical A nanoscale hollow tubular-structured Ta/Organo-In composite was synthesized. The material exhibited a response value of 92.34 to 50 ppm triethylamine at 190 °C, along with superior comprehensive performance in stability, sensitivity, and selectivity. Remarkably, it demonstrated detectable responses even at room temperature. The development of chemical sensor technology has been significantly advanced amine-responsive materials with the characteristics of rapid response, stability, and low-power consumption. This study synthesize Organo-In materials, and further explored the composite formation between tantalum (Ta) powder, and the organometallic indium (Organo-In). The morphology and structure of the resulting material were characterized using SEM, TEM, XRD, HAADF, and XPS. Results demonstrate the Ta/Organo-In composite's exceptional triethylamine (TEA) selectivity: Showing 92.34 response to 50 ppm TEA at 190 °C with 9s/486 s response/recovery times, outperforming aldehydes/ketones/aromatics. Notably, the Ta/Organo-In prepared by the method in this study showed a response value of approximately 3.4 toward 50 ppm TEA at room temperature (about 25 °C), and the response values remained stable after 10 consecutive cycles, indicating the material's excellent reliability and potential for low-power applications in real-time TEA monitoring devices at room temperature. The selectivity and continuous gas sensing performance of Ta/Organo-In at room temperature are both acceptable. Furthermore, within the concentration range of 1–500 ppm, the response values of the Ta/Organo-In material to TEA followed a Logistic curve fitting with an R 2 of 0.99644. Finally, the selective response mechanism of materials to TEA was discussed.

The interfaces in heterostructure photocatalysts play an important role in charge migration, but the rational controllable interfacial construction remains a challenge. Herein, a covalently bonded interface with delocalized π bonds was controllably constructed via the encapsulation of UiO-66-NH2 nanoparticles in MUV-10 skeletons. The UiO-66-NH2/MUV-10 heterojunction enabled both efficient capture and conversion of CO2 and H2O. The delocalized π bond in the covalent interface efficiently accelerated interfacial charge migration, suppressed carrier recombination, and reduced the work function for electronic effusion. As a consequence, UiO-66-NH2/MUV-10 exhibited superior CO2 photoreduction activity with H2O under visible light irradiation in the gas–solid phase. The CO evolution rate reached as high as 38.7 μmol g−1 h−1, which surpassed that of most commonly reported gas–solid phase photocatalysts. This work not only provides a feasible strategy for the controllable construction of interfaces but also demonstrates the great potential of interfacial engineering for efficient photocatalysis and other related areas.

The development of acetone gas sensors is desirable but challenging for both air quality monitoring and medical diagnosis. Herein, starting from bimetallic In/Ga metal–organic frameworks (MOFs) (MIL-68 (In/Ga)), a facile strategy is proposed to couple with zinc ions to design In/Ga oxide (IGO)@ZnO core–shell nanotubes for efficient acetone detection. In such a heterostructure, tiny ZnO nanoparticles are closely decorated on IGO nanotubes, which is beneficial to enlarge the specific surface area and create rich oxygen vacancies and heterojunction interfaces. Benefiting from the structural merits and synergetic effects, the IGO@ZnO-based gas sensor exhibits a low detection limitation (200 ppb), a high response, good linearity relationship between the sensing responses and wide testing acetone concentrations, and fast response and recovery time (6.8/6.1 s) with good selectivity and stability. These sensing performances strongly indicate the practical application to quantitatively detect acetone.

High-efficiency photoluminescence quaternary hexagon Zn–Cu–In–S (ZCIS) nanoplatelets (NPls) have been synthesized by a two-step cation exchange method, which starts with the In2S3 NPls followed by the addition of Cu and Zn. It is the first time that In2S3 NPls are used as templates to synthesize ZCIS NPls. In this paper, the reaction temperature of In2S3 is essential for the formation of NPls. The photoluminescence wavelength of NPls can be tuned by adjusting the temperature of Cu addition. To enhance the stability of the resulting NPls and to improve their optical properties, we introduced Zn2+ and obtained ZCIS NPls by cation exchange on the surface. It is worth noting that the obtained ZCIS NPls show a shorter fluorescence lifetime than other ternary copper sulfide-based NPls. This work provides a new way to synthesize high-efficiency, nontoxic, and no byproduct ZCIS NPls.

The sea urchin-like In 2 O 3 material was successfully synthesized through a simple hydrothermal method . Furthermore, the material underwent surface decoration without adding extra indium ions , resulting in the formation of a thin MIL-68(In) layer on the surface of In 2 O 3 . The obtained In 2 O 3 @MIL-68(In) retains the sea urchin-like morphology while acquiring an additional porous structure. Compared to pure In 2 O 3 , the composite exhibits a significant increase in specific surface area, leading to enhanced gas sensitivity. Notably, it demonstrates exceptional sensitivity towards formaldehyde gas, with a response of 18 at 100 ppm at 300 °C, up to six times more than pure In 2 O 3 . Moreover, In 2 O 3 @MIL-68(In) showcases remarkable selectivity and stability. These findings suggest that surface-modified MOF can enhance gas-sensitive properties.

The I-III-VI QDs Ag-In-S (AIS) exhibits excellent properties in photocatalysis because of the adjustable band gap, wide light absorption range, and multiple active sites. Introducing homologous or heterogeneous ions not only derives the composition into quaternary/ quinary quantum dots but also generates new sulfide QDs to form composites, which is an effective strategy to promote photoactivity. In this work, we in-situ synthesized the AIS/ZIS (AgIn 5 S 8 /Zn 4 In 2 S 7 ) composite photocatalyst by introducing Zn 2+ and changing the reaction temperature. We found that the composite photocatalyst could efficiently photodegrade larger concentrations of RhB than that of the previous reports. The superior photocatalytic activity was due to the formation of the type I high-low junction, which could effectively separate carriers. The photoelectrons on the CB of AIS reacted with dissolved oxygen to produce strongly oxidative O 2 – , which degraded RhB into intermediates and eventually into CO 2 and H 2 O. This work not only reports an excellent photocatalyst but also offers new ideas on the design and manufacture of highly efficient high-low junction photocatalysts.

Strategies to efficiently activate CO2 by strongly inhibiting the competitive hydrogen evolution reaction process are highly desired for practical applications of the electrochemical CO2 reduction technique. Here, we assembled a core–shell In@InOxHy architecture on carbon black by one-step reduction of NaBH4 as a CO2-to-formate catalyst with high selectivity. The stable CO2-to-formate reaction originates from the creation of steritic frustrated Lewis pairs (FLPs) on the InOxHy shell with In–OVs (OVs, oxygen vacancies) Lewis acid, and In–OH Lewis base. During CO2 reduction, the electrochemically stable FLPs are capable of first capturing and stabilizing protons to protonate FLPs to In–H Lewis acid and In–OH2 Lewis base due to its strong steric electrostatic field; then, CO2 is captured and activated by the protonated FLPs to selectively produce formate. Our results demonstrated that FLPs can be created on the surface of oxyphilic single-metal catalysts efficient in accelerating CO2 reduction with high selectivity.

The efficient and economic conversion of CO2 and renewable H2 into methanol has received intensive attention due to growing concern for anthropogenic CO2 emissions, particularly from fossil fuel combustion. Herein, we have developed a novel method for preparing Ni/In2O3 nanocatalysts by using porous MIL-68(In) and nickel(II) acetylacetonate (Ni(acac)2) as the dual precursors of In2O3 and Ni components, respectively. Combined with in-depth characterization analysis, it was revealed that the utilization of MIL-68(In) as precursors favored the good distribution of Ni nanoparticles (∼6.2 nm) on the porous In2O3 support and inhibited the metal sintering at high temperatures. The varied catalyst fabrication parameters were explored, indicating that the designed Ni/In2O3 catalyst (Ni content of 5 wt %) exhibited better catalytic performance than the compared catalyst prepared using In(OH)3 as a precursor of In2O3. The obtained Ni/In2O3 catalyst also showed excellent durability in long-term tests (120 h). However, a high Ni loading (31 wt %) would result in the formation of the Ni-In alloy phase during the CO2 hydrogenation which favored CO formation with selectivity as high as 69%. This phenomenon is more obvious if Ni and In2O3 had a strong interaction, depending on the catalyst fabrication methods. In addition, with the aid of in situ diffuse reflectance infrared Fourier transform spectroscopy and density functional theory (DFT) calculations, the Ni/In2O3 catalyst predominantly follows the formate pathway in the CO2 hydrogenation to methanol, with HCOO* and *H3CO as the major intermediates, while the small size of Ni particles is beneficial to the formation of formate species based on DFT calculation. This study suggests that the Ni/In2O3 nanocatalyst fabricated using metal–organic frameworks as precursors can effectively promote CO2 thermal hydrogenation to methanol.

Selective catalytic reduction of nitrogen oxides with methane (CH4-SCR) is an effective way to simultaneously eliminate NOx and CH4 emissions. Development of efficient CH4-SCR reaction system with high NOx reduction activity and selectivity is highly desirable for its commercial application. Herein, a two-part relay reaction system, including sequentially Co@S-1 and In-Ce/H-Beta catalysts, is designed for boosting CH4-SCR. In this system, the Co@S-1 with high redox ability boosts NO oxidation to NO2 and generates key intermediate CH3NO2 that can partially be in situ oxidized and the excessive can migrate to In-Ce/H-Beta. Meanwhile, the inner synergistic effect between InO+ and CeO2 species on In-Ce/H-Beta not only exhibits fair CH4-SCR performance, also facilitates the formation of NO- 3 species to react with the migrated CH3NO2 from Co@S-1. Benefiting from the combination between outer active sites synergy and inner active sites synergy, the simultaneous efficient conversion of NOx (T50 = 380 ℃) and CH4 (T50 = 425 ℃) with well durability is achieved.

The porous and tubular structure is conducive to improving performance of sensing materials. At present, how to obtain sensitive materials with unique porosity and high surface activity by green, low-cost and simple synthesis methods is still a challenge. In this work, novel In 2 O 3 porous microtubes were obtained by water etching of MIL-68-In and calcination methods for the first time. The as-prepared microtubes exhibit excellent NO 2 sensitivity at 50 ℃ (S=156–3 ppm NO 2 ), and the limit of detection is 50 ppb. The sensor also has good NO 2 detection ability in the actual environment. The excellent NO 2 sensing performance at low temperature is closely related to high surface activity of In 2 O 3 porous microtubes. Combined with TPD, in-stiu DRIFT and XPS technologies, the NO 2 sensing mechanism was detailed analyzed. This work provides useful guidance for constructing high performance NO 2 sensor. The excellent NO 2 sensing performance at low temperature makes a positive contribution to promoting the application of metal oxide sensors in environmental detection.

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.

The carbon-coated Ni (Ni@C) and Ni–In intermetallic compounds (IMCs) (Ni–In@C) catalysts were synthesized via combining one-pot hydrothermal method with glucose as carbon source and the carbonization under N 2 atmosphere. Their reactivities were compared in in situ aqueous phase selective hydrogenation of methyl palmitate to hexadecanol using methanol as a H 2 donor. The Ni@C catalyst dominatingly catalyzes decarbonylation/decarboxylation, accompanying with the serious C–C bond hydrogenolysis and methanation. In contrast, hexadecanol is mainly generated on Ni–In@C, where C–C bond hydrogenolysis and methanation are remarkably inhibited. This is ascribed to the geometric and electronic property of Ni–In IMCs. The hexadecanol yield reaches 84.0% under an optimal condition on Ni–In@C. The structure of NiIn IMC is hydrothermally stable even at 330 °C, and the Ni–In IMCs particles highly resist to sintering and leaching under harsh hydrothermal condition due to the confinement of carbon. Catalyst deactivation is mainly due to the carbonaceous deposition, and the catalyst reactivity is mostly recovered by the regeneration with CO 2 .
