Cu(In, Ga)(S, Se) 2 (CIGSSe) solar cell is one of the most promising thin-film solar cells with a record power conversion efficiency (PCE) of 23.6%. Conventional CIGSSe thin-film solar cells are usually fabricated on Mo-coated soda-lime glass substrate, thereby, the sunlight on the rear side cannot be utilized by the monofacial CIGSSe solar cells owing to the opacity of the Mo electrode. CIGSSe solar cells fabricated on transparent conductive oxide (TCO) electrode enable to fabricate bifacial solar cells, which can generate power on both sides of solar cells, so that bifacial solar cells have a high potential application in building-integrated photovoltaics. However, the PCEs of CIGSSe solar cells fabricated on TCO substrates are significantly lower than those of ones on Mo substrates. In this article, bifacial CIGSSe solar cells on fluorine-doped tin oxide (FTO) substrate are fabricated by using an ionic liquid-assisted solution approach and utilizing a MoO 3 thin film as an interface layer between FTO and CIGSSe absorber layer, yielding a front-side PCE of 9.73% and a back-side PCE of 1.77%.

White light emitting diodes (WLEDs) based on all-inorganic halide (CsPbX 3 , X = Cl, Br and I) perovskite quantum dots (QDs) have attracted broad attention due to their high brightness. However, their poor stability and anion-exchange reaction when utilized together are still the main challenges that impede their applications. Herein, a one-step in situ method under room temperature in air is proposed to synthesize CsPbBr 3 QDs coated with SiO 2 (CsPbBr 3 @SiO 2 ), where the whole process takes only 20 s. The as-prepared CsPbBr 3 @SiO 2 QDs samples present an enhanced stability in the thermal and polar-solvent environment, maintaining its high photoluminescence quantum yield (PLQY~75%). Thereby WLEDs are constructed by combining CsPbBr 3 @SiO 2 with red Ag–In–Zn–S QDs on InGaN blue chip, achieving a high color rendering index (CRI) of 91, a correlated color temperature (CCT) of 3689 K and a power efficiency of 40.6 lm W −1 .

Metal-organic frameworks (MOFs) as photocatalysts are promising candidates for environmental wastewater treatment owing to their tunable crystal structure, well-ordered donor–acceptor interface, and exceptional porosity. However, precise control over size and morphologies of MOFs to enhance adsorptive and photocatalytic performance is still a considerable challenge. Herein, the MIL-68(In)–NH 2 (MN) MOFs with special acicular structure are customized by a facile method, in which the growth of crystal nuclei is inhibited and regulated by pyridine. The formation mechanism of MN with different morphologies and size is introduced, and their photocatalytic activities are systematically explored by degrading model pollutants tetracycline (TC) and dyes under visible light irradiation. Benefiting from its high specific surface area and the exposed large lattice spacing facet, the wool-ball morphology MN (MN-W) with surface acicular nanostructure presents an optimum photocatalytic performance compared to other MN morphologies. The MN-W also exhibits excellent adsorption capacity, remarkable cyclic stability, and good practical organic wastewater treatment capability. The possible photodegradation mechanism and pathways are elucidated, demonstrating that h + is the primary reactive species, followed by •OH and •O 2 – radicals, responsible for the degradation of TC. This work is anticipated to tailoring design and modulate MOF photocatalysts for boosting the photocatalytic performance towards organic effluents remediation.

Lead-free double perovskites have superb luminescence properties for broad applications. However, increasing or improving near-infrared (NIR) photoluminescence (PL) is still a challenge. In this paper, a high-performance microcrystal is designed based on Tm 3+ heavily doped Cs 2 Ag 0.6 Na 0.4 In 0.9 Bi 0.1 Cl 6 (CANIBC), which realize both the self-trapped excitons (STEs) and Tm 3+ NIR emission. The emission mechanism and energy transfer (ET) process are studied by steady-state and time-resolved PL spectra. The ET efficiency from STEs to Tm 3+ can reach 38.3 %, and the NIR PL quantum yield of Tm 3+ can reach 22.7 %. Meanwhile, the PL spectra of Tm 3+ -doped CANIBC microcrystals (MCs) with different concentrations are used to investigate their temperature sensing properties based on both fluorescence intensity ratio (FIR) and lifetime. Based on the FIR, relative sensitivity ( S r ) can reach 2.93 % K −1 at 303 K. Moreover, based on lifetimes, S r can maintain more than 1.55 % K −1 from 303 to 453 K, and maximum S r can also achieve 2.38 % K −1 at 360 K. These excellent luminescence and sensing properties offer greater development potential in the field of NIR phosphor and thermometry.

It is essential to develop a highly efficient detection platform for tetracycline (Tc). Herein, based on well-designed hierarchical MIL-68(In)-NH 2 /MWCNT/CdS composites as a highly efficient transducer, a label-free visible light driven photoelectrochemical (PEC) aptasensor was systematically fabricated. Characterization results indicate that the forming of MIL-68(In)-NH 2 /CdS heterojunction remarkable facilitated the transfer and inhibited the recombination of charge carriers. Moreover, the transfer properties of multiwalled carbon nanotubes (MWCNTs) further improved the photoelectric conversion efficiency by adjusting electron transport routes. The aptamer as a biorecognition unit was grafted on the modified electrode by chemical bonding effect, and Tc molecules could be captured through the specific interaction of aptamer and Tc in solution. The concentration of Tc was detected by observing the fluctuation of photocurrent signals. Under optimized conditions, the proposed aptasensor showed the broad linear range from 0.1 nmol L −1 to 1 μmol L −1 with a low detection limit (LOD) of 0.015 nmol L −1 . Furthermore, the high sensitivity, excellent reproducibility and favorable stability of the PEC sensing platform indicated the potential applications for antibiotic residues detecting in environmental media.

Utilization of CO2 and its conversion to value-added chemicals are highly desirable to alleviate the environmental concerns caused by the massive anthropogenic CO2 emission. Although In2O3/Pd have been employed as efficient catalysts for hydrogenation of CO2 to methanol, the electronic effects by strong metal–support interaction (SMSI) between Pd and In2O3 are poorly understood, which is greatly affected by the morphology of In2O3. Herein, we use MIL-68(In) nanorod as a morphological template for the synthesis of hollow In2O3 nanotubes (h-In2O3) and the preparation of supported Pd catalysts for CO2 hydrogenation to methanol. Interestingly, loading Pd on h-In2O3 showed a much higher performance than In2O3 with other morphologies, which exhibited almost unchanged CO2 conversion of 10.5%, methanol selectively of 72.4%, and methanol space-time yield of 0.53 gMeOH h–1 gcat–1 over 100 h on stream at 3 MPa and 295 °C. After in-depth characterizations, we found that the different electronic properties of Pd species on In2O3 can be finely tuned by diverse synthetic conditions, which were responsible for high activity and stability. The molar fraction of Pd2+ species in the h-In2O3/Pd catalyst reached 67.6%, 3.2 times that of the In2O3@Pd catalyst (21.3%), due to the different surface chemistry of In2O3. Density function theory results indicated that the Pd donated more electrons to the curved In2O3 (222) surface than the pristine surface, and Pd2+ was critical to facilitate H2 adsorption and formation of the surface oxygen vacancy. This work demonstrates that controlling the morphology of In2O3 can modify both the Pd electronic property and SMSI between Pd and In2O3, which are the origins of the high catalytic performance.

Periodate (PI) is widely used in advanced oxidation processes (AOPs) due to its unique oxidizing properties. However, excessive residual PI can negatively impact water quality. Here, we report a novel dual-ligand metal-organic framework (MOF), In-MOF, which exhibits excellent performance for PI detection in complex environmental water samples. In-MOF was constructed using 2-aminoterephthalic acid (BDC-NH 2 ) and biphenyl-3,3′,5,5′-tetracarboxylic acid (H 4 BPTC) ligands and features internal molecular hydrogen bonding and photoinduced electron transfer (PET) effects, significantly enhancing its selectivity and stability in aqueous environments. In its native state, the fluorescence of In-MOF is quenched due to its intrinsic PET effect. However, upon interaction with PI, the disruption of internal hydrogen bonds and inhibition of the PET process results in the emergence of bright blue fluorescence. Experimental results demonstrate that In-MOF maintains high selectivity for PI even in the presence of common oxidants and by-products (such as iodate) found in industrial processes. Furthermore, a paper-based platform was developed for on-site PI detection, further expanding the application potential of this MOF-based sensor for environmental monitoring. These findings highlight In-MOF as an efficient, cost-effective, and environmentally friendly solution for periodate detection across various water sources.

Its application values on the acute stroke were assessed and the corresponding mechanism was investigated simultaneously. Firstly, the levels of inflammatory response in the astrocytes were evaluated by ELISA by measuring the content of inflammatory cytokines released into cerebrospinal fluid. Additionally, the miRNA199a relative expression levels in astrocytes were measured via exploiting real time RT-PCR. Molecular docking simulation demonstrated that synthesized In ion complex exhibited excellent biological activities, multiple binding interactions were formed by the carboxyl groups on the In ion complex.

Control release of pesticides based on target plant characteristics is highly desirable for improving the effective utilization rate and reducing non-target organism risks. Here, the controlled release formulations (Cu-CS@IN@MIL-100 (Fe)) were successfully prepared by employing MIL-100 (Fe) as the carrier material, indoxacarb (IN) as the model pesticide, and chitosan (CS) as a coating to chelate copper ions by chemical crosslinking. The prepared Cu-CS@IN@MIL-100 (Fe) had an acceptable loading content (36.25 %). The introduction of CS and copper ions endowed it with sustained release properties under weak acidity conditions like cotton leaves. The laboratory bioassay experiments showed that Cu-CS@IN@MIL-100 (Fe) had practical good insecticidal activity (LC 50 = 4.936 mg/L) in controlling Helicoverpa armigera larvae. For long-term control efficacy experiments, after 14 days of application, the Cu-CS@IN@MIL-100 (Fe) treatment (73 %) mortality of Helicoverpa armigera larvae was significantly higher than the 15 % indoxacarb suspension concentrates (SC) treatment (27 %). Moreover, Cu-CS@IN@MIL-100 (Fe) had no adverse effect on cottonseed germination and the acute toxicity to Chrysopa pallens larvae was significantly lower than IN SC. Therefore, MIL-100 (Fe) could be used as an ecological safety carrier for pesticide delivery to improve IN effective utilization and reduce non-target organism risks.

The band alignment of Cu 2 ZnSn(S,Se) 4 (CZTSSe)/CdS(In) in novel CZTSSe solar cells without a ZnO window layer has been initially investigated in our previous studies. However, the In content of CdS(In) diffused into the absorber is low, and the ability to regulate the band arrangement is limited. In this work, we employ In-ion-doped absorbers to adjust defects. However, this approach leads to a significant loss in short-circuit current density (Jsc). To address this, Cd is introduced to enhance Jsc through grain growth promotion and morphological improvement, thereby offsetting the Jsc loss induced by In doping. The co-doping of In and Cd reduces the conduction band offset (CBO) from 0.28 eV to 0.21 eV, thereby inhibiting carrier recombination and enhancing transport efficiency. Additionally, the concentration of bulk defects is reduced by an order of magnitude. As a result, the fill factor (FF) increased from 56.97 % to 60.08 %, Jsc increased from 37.10 mA/cm 2 to 38.66 mA/cm 2 , and open-circuit voltage (Voc) increased from 431.64 mV to 440.48 mV. Finally, the power conversion efficiency (PCE) of CZTSSe solar cell is enhanced to 10.23 %.

The efficient catalytic hydrogenation of CO 2 to methanol is a promising route for CO 2 emission mitigation and utilization. Recently, the Co-In based materials as one of the excellent alternative catalysts for CO 2 hydrogenation to methanol have received intense attention. Herein, we developed new and efficient Co-In based catalysts (the composite of Co 3 InC 0.75 and In 2 O 3 ) by Prussian Blue analogues (PBA) pyrolysis . And a series of Co 3 InC 0.75 -In 2 O 3 composites with tunable proportion of Co 3 InC 0.75 and In 2 O 3 has been prepared. The experimental results demonstrate the Co 3 InC 0.75 -In 2 O 3 catalysts have high catalytic CO 2 hydrogenation performance into methanol, reaching a methanol yield up to 0.62 g MeOH g cat −1 h −1 at 300 °C, 5 MPa, 24000 cm 3 STP g cat −1 h −1 , and H 2 /CO 2 = 3:1, the high reaction stability and air resistance. The synergetic effects between Co 3 InC 0.75 and In 2 O 3 for the enhanced methanol production were confirmed by a series of characterizations, and a positive correlation between methanol production activity and the fraction of Co 3 InC 0.75 /In 2 O 3 was well established.

Rechargeable aqueous zinc-metal batteries, considered as the possible post-lithium-ion battery technology for large-scale energy storage, face severe challenges such as dendrite growth and hydrogen evolution side reaction (HER) on Zn negative electrode. Herein, a three-dimensional Cu-In alloy interface is developed through a facile potential co-replacement route to realize uniform Zn nucleation and HER anticatalytic effect simultaneously. Both theoretical calculations and experimental results demonstrate that this bifunctional Cu-In alloy interface inherits the merits of low Zn-nucleation overpotential and high HER overpotential from individual copper and indium constituents, respectively. Moreover, the dynamical self-reconstruction during cycling leads to an HER-anticatalytic and zincophilic gradient hierarchical structure, enabling highly reversible Zn chemistry with dendrite-free Zn (002) deposition and inhibited HER. Moreover, the improved interface stability featured by negligible pH fluctuations in the diffusion layer and suppressed by-product formation is evidenced by in-situ scanning probe technology, Raman spectroscopy, and electrochemical gas chromatography. Consequently, the lifespan of the CuIn@Zn symmetric cell is extended to more than one year with a voltage hysteresis of 6 mV. Importantly, the CuIn@Zn negative electrode is also successfully coupled with high-loading iodine positive electrode to fabricate Ah-level (1.1 Ah) laminated pouch cell, which exhibits a capacity retention of 67.9% after 1700 cycles.
