In recent years, conductive hydrogel based sensors have been widely used because of their flexibility and convenience, especially in strain sensing, handwriting recognition, object shape recognition and so on. In this research, the conductive hydrogel with “two-in-one” structure was well designed to avoid the agglomeration and leakage of liquid metal by using polyvinylpyrrolidone modified liquid gallium indium alloy/polydopamine composite hydrogel as the top layer and hydrogen bonding crosslinked waterborne polyurethane/poly(vinyl alcohol) composite hydrogel as the bottom layer, respectively. Finally, a hydrogel based sensor with excellent stretchability and sensitivity was successfully obtained. The tensile strength of the prepared composite hydrogel exceeded 2 MPa. The elongation at break could be greater than 500 %. The toughness was greatly improved due to the introduction of waterborne polyurethane , which was greater than 7.5 MJ/m 3 . The GF value of the sensors reached 4.54. More interestingly, the mechanical self-healing ability of composite hydrogel prepared by adding polydopamine, reached about 70 % of the original. The hydrogel based sensor was able to use for gesture recognition and controlling the manipulator in human-computer interaction. This research can provide a practical idea to achieve advanced intelligent wearable sensing.

Nano sized semiconductor oxide type gas sensor has been widely studied due to its high sensitivity. Therein, one-dimensional nanostructures have attracted a lot of interests. In this work, nanofiber and nanotube of one-dimensional nano sized cobalt–indium combined oxide were fabricated by single nozzle electrospinning. The ethanol gas sensing properties of Co–In oxide nanofiber and nanotube were investigated. The morphologies were observed by scanning electron microscopy (SEM). The elementary composition was characterized by powder X-ray diffraction (XRD), and energy-dispersive X-ray spectrometry (EDS). The BET surface area of the nanotube can be calculated to be 22 m 2 /g, which is larger than 18 m 2 /g of nanofiber. The results reveal that one-dimensional nanotubes have larger sensitivity to ethanol than that of one-dimensional nanofibers. Besides, the comparison of their response and recovery curves was tested. The selectivity was also investigated. Both nanofibers and nanotubes show a fast response and excellent selectivity.

We report a facile method for the synthesis of size-controlled triangular CuInS 2 (CIS) semiconductor nanocrystals (NCs) in the organic phase, and then, molecular metal chalcogenide complexes capped CIS NCs can be synthesized by exchanging original organic compounds with (NH 4 ) 4 Sn 2 S 6 inorganic ligands in environmentally benign solvent. The properties of CIS NCs (coated by both organic and inorganic ligands) were characterized by UV–Vis spectroscopy, fourier transform infrared, transmission electron microscopy, X-ray diffraction, thermogravimetric analysis, X-ray photoelectron spectroscopy, and dynamic light scattering. CuInS 2 NCs (before and after ligand exchange) films were spin coated on cleaned ITO glass substrates, and the charge transport properties were detected by current-voltage characteristic. We observed that the ligands on the surface of CIS NCs have been exchanged successfully, and the electrical transparency of (NH 4 ) 4 Sn 2 S 6 -CIS NCs films was obviously increased than CIS NCs with organic capping ligands.

Extraction of In(Ⅲ) from the tail liquid of zinc ore which possesses the large amounts of Zn(Ⅱ) and the characteristics of highly acidity, remains a critical challenge. Adsorption method can be considered as an effective and green strategy to recovery In(Ⅲ). However, the adsorption capacity of mostly reported adsorbents is unsatisfactory toward In(Ⅲ) in the acidic environment. In this work, an effective In(Ⅲ) trap is developed by using a mild, simple strategy that introduces zirconium glyphosine coordination networks in situ loaded on carbon nanotube . Benefiting from the characteristics of abundant carboxyl and phosphate groups, excellent hydrophilicity and thermal stability, the resultant zirconium glyphosine carbon nanotube composite (xZrGP-CNT) exhibits remarkable adsorption capacity (193.72 mg g - 1 ) toward In(Ⅲ) under pH 2.5 exceeded most of the reported adsorbents, and its adsorption behavior is consistent with pseudo-second order kinetic and Langmuir isotherm models. In addition, the obtained 2ZrGP-CNT shows prominent kinetics that reaches equilibrium only within 2 h, superior selectivity and excellent regeneration performance for In(Ⅲ) capture, which indicates the highly encouraging potential for the recovery of In(Ⅲ) in practical ore fluids. Our work poses a new way to recovery of In(Ⅲ) under acidic environments with superior adsorption performance and broadens the potential of organocphosphonates for recovering In(Ⅲ).

The impact of Indium (In) doping upon the catalytic performance of Pd-Cu/Al 2 O 3 for carbon monoxide preferential oxidation (CO-PROX) in hydrogen (H 2 ) rich atmosphere at low temperature has been studied. A series of catalysts with extremely low palladium (Pd) loading (0.06 wt%) are synthesized by the facile co-impregnation method. When the In/copper (Cu) atomic ratio equals 0.25, Pd-Cu-In 0.25 /Al 2 O 3 can keep 40% CO conversion and 100% carbon dioxide (CO 2 ) selectivity at least 120 min at 30 °C, which is significantly superior to the catalytic performance of Pd-Cu/Al 2 O 3 . The elaborate characterization findings reveal that the added In species to Pd-Cu/Al 2 O 3 causes Indium oxide (In 2 O 3 ) to generate, which produces the interaction of In 2 O 3 with Pd-Cu/Al 2 O 3 , further promoting the dispersion of copper chloride hydroxide (Cu 2 Cl(OH) 3 ). Moreover, the modification of In facilitates the re-oxidation of Pd 0 to Pd + through reducing the formation of palladium hydride (PdH x ) during the CO-PROX reaction. Meanwhile, the addition of In leads to the decrease of Cu + electron cloud density, making it easier to be oxidized to Cu 2+ . Collectively, the easy re-oxidation of Pd 0 and Cu + is favorable to fulfill the Wacker cycle between Pd and Cu species, thus improving the catalytic performance for CO-PROX.

A growing need for high-energy-density lithium metal batteries appeal for utilize ultrathin (≤50 μm) free-standing Li metal anodes . However, challenges such as the formation of an unstable solid electrolyte interphase and the lithium dendrites growth have led to poor cycling performance and safety concerns, limiting the commercial viability of thin lithium metal anodes. This work introduces a facile approach by designing and fabricating an ultrathin Li-In alloy anode through in-situ vacuum melting and codirectional continuous rolling. The rolled ultrathin Li-In anode achieves the induction of uniform epitaxial electrodeposition of Li(110), which is attributed to the lithiophility of the densely distributed In₃Li₁₃ alloy phase and the coherent heterogeneous relationship between textured In₃Li₁₃(311) and Li(110).The symmetrical cell assembled by 50 μm Li-In alloy anode exhibits a prolonged lifespan for 1800 h under the conditions of 1 mA cm -2 and 3 mAh cm -2 . Meanwhile, the LiFePO 4 ||Li-In (50 μm) full cell achieves sTable 450 cycles with a retention of 90.3 % at 2 C (1 C = 170 mA g -1 ). This work paves the path for the practical ultrathin Li anode for commercializing the lithium metal batteries .

Exploring a zero-dimensional (0D) hybrid halide with a large Stokes shift and efficient broad-band emission is highly desirable due to its enormous potential for solid-state lighting (SSL) application. However, it is still challenging to develop a highly emissive 0D hybrid halide with low toxicity and remarkable stability. Herein, we developed a novel indium-based metal halide A5In2Cl16·4H2O (A = doubly protonated 1,4-diaminobutane) whose inorganic octahedrons are completely isolated by the organic cations to form the 0D structure. Experimental and theoretical studies confirmed that Sb-doped A5In2Cl16·4H2O exhibits broad yellow emission with a photoluminescence quantum yield (PLQY) of up to 98%. The intense yellow emission can be attributed to the radiative recombination of triplet self-trapped excitons (STEs) in [SbCl6]3– octahedrons caused by the strong electron–phonon coupling. Benefiting from the excellent stability and photoluminescence performance, A5In2Cl16·4H2O:15%Sb was used as the yellow phosphor to prepare a white-light-emitting diode (WLED) device with a color rendering index of 87.8 and a luminous efficiency of up to 36.18 lm/W, demonstrating its potential in SSL applications. This work provides a guidance for developing environmentally friendly, efficient, and stable ultraviolet (UV)-excited broad-band emission materials.

At present, the processes of recovering indium-gallium-zinc oxide (IGZO) scraps through hydrometallurgy, pyrometallurgy, or molten salt electro-deoxidation are cumbersome, impurities cannot well be effectively removed, and the environmental benefits are inferior. We herein firstly propose a facile electrochemical method for upcycling of IGZO scraps in ammonium salt aqueous solution at ambient temperature. The feasibility of electro-deoxidation of IGZO in aqueous solution has been verified, using IGZO scraps without further crushing as the cathode and anode. The electro-deoxidation behavior of various oxides exhibits differentiation, among which indium oxide is the most easily deoxidized. This difference hinders the formation of a dense alloy layer on the surface of the IGZO substrate, facilitating the transfer of oxygen ions and enabling continuous electro-deoxidation. Impurities such as aluminum and silicon can be significantly removed, with removal rates of 95.8 % and 75.7 %, respectively, which is also attributed to the difference in electrochemical reduction ability between impurity oxides and IGZO, as well as the solid-state existence of cathode products. The process of upcycling IGZO scraps contributes to recovery with straightforward operation and more adaptable implementation environment, which endows it with optimistic application potential.

With the growing demands on environmental protection and human health, numerous efforts have been devoted to the high-efficiency detection of formaldehyde gas. Herein, a simple and green manner was adopted to generate a 3D/0D heterogeneous structure. It was found that the morphology evolution of the In 2 O 3 -based sample could be fine-tuned through changing the addition concentration. Impressively, the unique hydrangea-like structure was assembled by connecting In 2 O 3 nanosheets. Furthermore, the carbon quantum dots were incorporated to upgrade the performance. The hydrangea-like IO-2@CQDs, hence, exhibits remarkable sensitivity, excellent response repeatability, superior selectivity as well as reliable long-term stability at 160 °C. An outstanding limit of detection can be as low as 86.23 ppb. In addition, the corresponding CQDs sensitization mechanism was comprehensively elaborated with experimental performance, DFT calculations (16 models, 41 images), and surface depletion theory. The active surface sites, n - p hetero-interface, and unique hydrangea-like morphology account for the boosted HCHO-sensitive performance. This work not only highlights the promising combination of metal oxides and CQDs but also provides valuable inspiration and theoretical perspectives for 3D/0D heterojunction construction.

Prolonged exposure to ethanol gas in the air can have deleterious effects on the human respiratory system and even pose an explosion risk. Therefore, it is imperative to monitor the concentration of ethanol gas and reliably detect its presence. In this study, tungsten-doped indium oxide (W-In 2 O 3 ) nanocomposites were synthesized by a hydrothermal method and utilized in gas sensors. The microstructures and morphologies of the nanocomposites were examined using various analytical methods, and the results indicated that W-In 2 O 3 was successfully synthesized. For instance, at optimal temperatures (280 °C) the gas-sensitive characteristics of W-In 2 O 3 composites were examined in response to varying ethanol gas concentrations (1−100 ppm). In particular, the sensor with a doping concentration of 10 % provided the best performance, as compared to the pure In 2 O 3 sensor, and displayed the highest response to 100 ppm of ethanol (33.2). Furthermore, this response is approximately 1.5–2 times better than that of pure In 2 O 3 , and simultaneously, in a cyclic test, the sensors consisting of W-In 2 O 3 exhibited excellent selectivity, fast response, short recovery times (10 and 60 s, respectively), good repeatability, and stability. In particular, the shift in microcrystal size caused by W doping was responsible for the notable augmentation of the sensitivity to ethanol, suggesting that the sensor may have potential applications for the detection and monitoring of ethanol gas.

The catalytic reduction of nitrate is a promising technology for groundwater purification because it transforms nitrate into nitrogen and water. Recent studies have mainly focused on new catalysts with higher activities for the reduction of nitrate. Consequently, metal nanoparticles supported on mesoporous metal oxides have become a major research direction. However, the complex surface chemistry and porous structures of mesoporous metal oxides lead to a non-uniform distribution of metal nanoparticles , thereby resulting in a low catalytic efficiency. In this paper, a method for synthesizing the sustainable nitrate reduction catalyst Pd–In/Al 2 O 3 with a dimensional structure is introduced. The TEM results indicated that Pd and In nanoparticles could efficiently disperse into the mesopores of the alumina. At room temperature in CO 2 -buffered water and under continuous H 2 as the electron donor, the synthesized material (4.9 wt% Pd) was the most active at a Pd–In ratio of 4, with a first-order rate constant ( k obs = 0.241 L min −1 g cata −1 ) that was 1.3× higher than that of conventional Pd–In/Al 2 O 3 (5 wt% Pd; 0.19 L min −1 g cata −1 ). The Pd–In/mesoporous alumina is a promising catalyst for improving the catalytic reduction of nitrate.

In this work, we fabricate a semitransparent BiVO4 photoanode via the synergistic effect of indium (In) doping and anoxic annealing. An optimized photocurrent density of 3.6 mA cm–2 at 2 V versus reversible hydrogen electrode is obtained in a sacrificial free electrolyte system (AM 1.5G 100 mW cm–2). In-doping increases the difficulty to form bonds between Bi atoms and O atoms in the crystal bulk. Thus, quasi-oxygen vacancies in the bulk of the BiVO4 crystal can be induced under anoxic annealing to increase the mobility, lifetime, and concentration of the photogenerated carriers. On the other hand, anoxic annealing can inhibit the conversion rate of the BiOI nanosheet arrays to BiVO4 to form a nanonet structure with a large surface reaction area. Therefore, through a simple In-doping and controlled anoxic annealing process, the photogenerated carriers and the nanomorphology of BiVO4 photoanode are synergistically optimized.
