The recovery of valuable elements from spent copper–indium–gallium–diselenide solar cells has been a topic of considerable interest. In this study, based on the elemental ratios in the leachate of spent solar cells, a multi-template thermos-responsive imprinted polymer (GIS-TIIP) was prepared by combining thermo-responsive technology and imprinted technology. This polymer was used for the simultaneous and proportional selective separation and purification of gallium, indium, and selenium from the leachate. The structure and performance of GIS-TIIP were systematically characterized through Fourier Transform Infrared Spectroscopy, Scanning Electron Microscopy-Energy Dispersive Spectrometry, Transmission Electron Microscopy, Brunauer-Emmett-Teller surface area and pore size analysis, Thermogravimetric Analysis, X-ray Photoelectron Spectroscopy, and Inductively Coupled Plasma-Atomic Emission Spectroscopy. The structure of GIS-TIIP responded to temperature changes. At 35 °C, maximum adsorption capacities were 0.0162 mmol/g for Ga 3+ , 0.0671 mmol/g for In 3+ , and 0.1001 mmol/g for SeO 3 2− . At 25 °C, maximum desorption ratios were 72.65 % for Ga 3+ , 75.33 % for In 3+ , and 69.34 % for SeO 3 2− . The ratio of maximum adsorption capacities for the three target ions (1: 4.142: 6.179) was close to the ratio of the molar amounts of template substances added during the synthesis (1:4:8). The adsorption process of GIS-TIIP fitted better with the pseudo-first-order kinetic model and the Langmuir model. When GIS-TIIP was applied to the diluted leaching solution, the purity of the target elements increased from 55.99 % to 80.98 % after a single adsorption/desorption cycle. The ratio of gallium, indium, and selenium was found to be 1: 4.263: 5.509, indicating the potential for alloy recovery and recycling. After 10 cycles of repeated use, GIS-TIIP still retained 75.71 % of its original adsorption capacity.

Electroreduction of CO 2 into beneficial products is integral to attaining carbon neutrality. Herein, we detail a series of anti-perovskite nitrides InNNi 3− x V x ( x = 0, 0.2, 0.4, 0.6, 0.8) to be highly effective CO 2 RR. The InNNi 2.4 V 0.6 demonstrated exceptional conversion of CO 2 to formate, achieving an optimal Faraday efficiency (FE) of 93.6 % at −0.754 V versus RHE. It also exhibited a partial current density of 200 mA cm −2 at −1.1 V versus RHE, along with remarkable stability in an H-type cell. Electrochemical tests, X-ray absorption fine structure, and theoretical calculations demonstrated that in addition to altering InNNi 3 electronic structure, V doping results in lattice distortion in NiN 3 octahedron, increasing the lattice spacing of InNNi 2.4 V 0.6 (111) surface, exposing more active sites. This enhances its ability to adsorb the reaction intermediate *OCHO, thereby facilitating the conversion of CO 2 into formate. This research offers a viable approach for optimizing an electrocatalyst to convert CO 2 to valuable products.

The design of semiconductor metal oxides (SMOs) with well-ordered porous structure has attracted tremendous attention owing to their larger specific surface area. Herein, three-dimensional inverse opal In2O3 microspheres (3D-IO In2O3 MSs) were fabricated through one-step ultrasonic spray pyrolysis (USP) which employed self-assembly sulfonated polystyrene (S-PS) spheres as a sacrificial template. The spherical pores observed in the 3D-IO In2O3 MSs had diameters of about 4 and 80 nm. Subsequently, the catalytic palladium oxide nanoparticles (PdO NPs) were loaded on 3D-IO In2O3 MSs via a simple impregnation method, and their gas sensing properties were investigated. In a comparison with pristine 3D-IO In2O3 MSs, the 3D-IO PdO@In2O3 MSs exhibited a 3.9 times higher response (Rair/Rgas = 50.9) to 100 ppm acetone at 250 °C and a good acetone selectivity. The detection limit for acetone could extend down to ppb level. Furthermore, the 3D-IO PdO@In2O3 MSs-based sensor also possess good long-term stability. The extraordinary sensing performance can be attributed to the novel 3D periodic porous structure, highly three-dimensional interconnection, larger specific surface area, size-tunable (meso- and macroscale) bimodal pores, and PdO NP catalysts.

Nanoscale ternary chalcogenides have attracted increasing research interest due to their merits of tunable properties and diverse applications in energy and biomedical fields. In this article, silver indium sulfide quantum dots supported by glutathione and polyethyleneimine as dual-ligands have been synthesized through an environmentally friendly and reproducible aqueous method. An emission quantum yield up to 37.2% has been achieved by glutathione as co-ligand bearing electron-rich groups, much higher than that of polyethyleneimine coated quantum dots (4.97%). Both spectroscopic and structural characterizations demonstrate that the photoluminescence enhancement is attributed to change of surface properties by glutathione as co-ligand. Dynamic light scattering (DLS) results and thermogravimetric analysis (TGA) reveal that glutathione covers the QDs with a higher density on the nanocrystal surface than other co-ligands. Therefore, it can effectively passivate the surface trap centers, thus decreasing the non-radiative emission. Moreover, the resultant silver indium sulfide quantum dots present surprisingly long lifetime of 3.69 μs, excellent fluorescent stability and low cytotoxicity, which enables them to be ideal candidate for real-time bioimaging.

Designing three-dimensional carbon skeleton represents an effective strategy for achieving dendrite-free potassium metal batteries. Herein, a freestanding electrode composed of carbon nanofibers loaded with potassiophilic Gallium–indium-nickel alloy nanoparticles (GaInNi@CNF), synthesized with the assistance of liquid metal (GaIn), is proposed as the anode host for the potassium metal batteries. The incorporation of GaIn enables the formation of a GaInNi alloy with nickel, thereby enhancing the adsorption energy of potassium. The synergistic effect of uniformly distributed alloy nanoparticles and their surrounding edge graphite carbon promotes uniform nucleation and stable potassium deposition. With the K-GaInNi@CNF-based modified electrode, the assembled K-GaInNi@CNF symmetric cells can achieve stable cycling over 800 h at 2 mA cm–2. Full cells with PTCDA cathode and K-GaInNi@CNF anode exhibit high stability (with a capacity retention rate of 81.75% for 800 cycles at 1 A g–1) with 99% Coulombic efficiency. Additionally, the cycle performance of GaInNi@CNF||KPTCDA anode-free cells is studied, and 77.52% capacity retention is achieved at 0.05 A g–1 after 50 cycles. This liquid metal-assisted method described in this study provides a strategy in developing electrodes for rechargeable batteries.

Chiral organic-inorganic hybrid perovskites (OIHPs) exhibit exceptional optical and chiral properties, demonstrating potential for 3D display, circularly polarized light-emitting diodes (CP-LEDs), and CPL switches. However, the construction of chiral OIHPs often relies on chiral building blocks, limiting chemical diversity, and possessing challenges in achieving large asymmetry factor ( g lum ) without sacrificing photoluminescence quantum yield (PLQY). Here, Chiral DMA 4 In 1- x Sb x Cl 7 (DMA = dimethylammonium, x = 0 to 1) with superior circularly polarized luminescence (CPL) are successfully constructed based on achiral building blocks DMA + and metal halides. By optimizing the Sb 3+ content, bright white emission with a high PLQY of 69.13% is achieved, as well as near-unity PLQY yellow emission and strong CPL signals with a g lum of up to +1.40 × 10 −2 , exhibiting a performance comparable to state-of-the-art chiral OIHPs. Combining optical characterizations and theoretical calculations reveal that these intriguing properties originate from the intrinsic chiral helical structures and a pair of perfect complementary color emissions in DMA 4 In 1- x Sb x Cl 7 . In addition, DMA 4 In 1- x Sb x Cl 7 exhibit excellent thermal stability and mild thermal quenching in the temperature range of 300 to 420 K. These fascinating properties suggest that DMA 4 In 1- x Sb x Cl 7 have significant applications in white light-emitting diodes (WLED), 3D displays and anti-counterfeiting.

Relatively small amounts of In-doped Mo(O,S) 2 (IMS) catalysts (10%, 20%, and 30%) were deposited on cellulose nanofiber (CNF) by cross-linking them with functional groups of siloxane and epoxy to form CNF-IMS hybrid composites. The as-prepared hybrid composites were characterized and tested their performances toward the photo degradations of cationic (MB and RhB) and anionic (MO) dyes. As indium was doped into Mo(O,S) 2 lattice to form solid-solution, the charge transfer and photocarrier separation during the catalytic reaction were simultaneously enhanced as probed with electrochemical impedance spectroscopy and photoluminescence measurements, respectively. To ensure the catalyst on CNF was well deposited and recyclable, the hybrid composite was evaluated with a reusability experiment to show the stability performance in degrading organic dyes. It was found the environmentally friendly CNF-IMS hybrid composite was relatively stable during the reusability experiment, indicating no catalyst powder was leached out during the photocatalytic reaction. The photoreaction mechanism was convinced by radical-scavenging experiments to show that hydroxyl and superoxide played essential roles for the organic dye degradations in visible-light illuminated conditions. The cross-linked organic/inorganic hybrid catalyst showed a prospective visible light active material not only to solve the environmental issue due to the leaching of nanoparticles but also to lower the post-treatment/recycling cost of photocatalyst in industrial application.

Although all-inorganic CsPbBr x I 3− x perovskite quantum dots (PeQDs) are increasingly being used as a competitive material for pure red perovskite light-emitting diodes (PeLEDs), they suffer from low luminescent ability and poor stability. In this study, an In 3+ -doped CsPbBr x I 3− x PeQD solution exhibits a near-unity photoluminescence quantum yield (PLQY) of ≈99.8% and superior stability for more than half a year in atmosphere. As far as known, this is the highest PLQY and stability achieved for mixed halide PeQDs. In 3+ ion doping not only reduces the surface vacancy defects because of the partial substitution of Pb 2+ by the smaller radii of In 3+ ions, but also enhances the formation energy of CsPbBr x I 3− x PeQDs based on first-principles calculations. Compared with pristine LEDs based on CsPbBr x I 3− x , the pure red PeLEDs based on In 3+ -doped CsPbBr x I 3− x display a higher luminance of 423 cd m -2 , fivefold external quantum efficiency improvement up to 11.2%, and increased stability, providing a feasible and promising perspective for developing In 3+ -doped CsPbBr x I 3− x PeQDs applied efficiently in advanced light emitters for solid-state lighting and displays.

As an n-type semiconductor, In 2 O 3 is considered a promising photocatalyst for producing amino acids using biomass derivatives as precursors. However, similar to other intrinsic semiconductors, In 2 O 3 suffers from poor charge dynamics. Herein, we show the synthesis of Mo-doped In 2 O 3 (Mo-In 2 O 3 ) with a porous rod-shaped structure through a one-step solvothermal reaction followed by calcination. Under visible-light irradiation, Mo-In 2 O 3 achieves a high conversion rate of 81% for the reaction that transforms lactic acid into alanine with a selectivity of 91%. Spectroscopic techniques and density functional theory calculations reveal that Mo doping introduces defect states slightly below the conduction band of In 2 O 3 , which improves the separation of photogenerated electron-hole pairs. In addition, Mo atoms on the surface form extra adsorption and reaction centers that greatly enhance the reaction rate. This work provides insights into the development of transition metal-doped semiconductor photocatalysts to produce amino acids.

This work reports a novel and effective method for the preparation of the copper-indium bimetallic electrocatalysts by the in situ growth of indium-based metal organic frameworks on oxidized copper foils as the precursor. Compared with the oxide-derived copper and the copper-based carbon material derivative grown in situ on oxidized copper foils, the as-prepared copper-indium electrocatalyst with a self-supporting structure, high roughness factor and rich lattice defects exhibits a superior CO Faradaic efficiency of 95% and good stability for the 36-h potentiostatic test at −0.6 V versus a reversible hydrogen electrode. Density functional theory calculations indicated that the indium atoms occupying the surface copper vacancy defects show lower free energy needed for the formation of *COOH and more difficult desorption of *H than indium atoms, supported on the perfect copper surface. Thereby, the copper-indium catalyst promotes CO 2 electroreduction to CO and strongly inhibits hydrogen evolution.

Spin chiral anisotropy (SChA) refers to the occurrence of different spin polarization in antipodal chiral structures. Herein, we report the SChA in diamagnetic chiral mesostructured In 2 O 3 films (CMIFs) with manifestation of chirality-dependent magnetic circular dichroism (MCD) signals. CMIFs were grown on fluorine-doped tin dioxide conductive glass (FTO) substrates, which were synthesized via a hydrothermal route, with malic acid used as the symmetry-breaking agent. Two levels of chirality have been identified in CMIFs: primary nanoflakes with atomically twisted crystal lattices and secondary helical stacking of the nanoflakes. CMIFs exhibit chirality-dependent asymmetric MCD signals due to the different interactions of chirality-induced effective magnetic field and external magnetic field, which distinguish from the commonly observed external magnetic fielddependent symmetric MCD signals. These findings provide insights into spin manipulation of spin-paired diamagnets.

Nearly monodisperse bullet-like Cu 3 ZnInSnS 6 (CZITS) nanocrystals with wurtzite structure were successfully synthesized through optimized noninjection method. The structure, composition, morphology and optical properties of CZITS nanocrystals were characterized by X-ray diffraction, energy dispersive spectrometry, transmission electron microscopy and UV-Vis–NIR absorption. Their suitable bandgap and photoresponsive behavior indicate a high potential application in the field of solar cells. The growth mechanism of the as-synthesized CZITS nanocrystals was preliminarily discussed. It was found that the formation of CZITS could be separated into two steps: nucleation of Cu 7 S 4 and growth of the CZITS main body.
