The diffraction patterns assigned to FeIn 2 S 4 are indexed to the cubic phase of FeIn 2 S 4 (JCPDS 80-0608), which is well agreement with the crystalline structure reported elsewhere (Chen et al 2005). The average crystallite size estimated by the Scherrer's equation was 21.7 nm.…”

The chalcogenide composite FeIn 2 S 4 was prepared by hydrothermal route and, for the first time, investigated as a heterogeneous catalyst in the photo-Fenton treatment for Ponceau 4R dye (C 20 H 11 N 2 Na 3 O 10 S 3 ) under visible irradiation. The composite was characterized by X-ray diffraction (DRX), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectrometry (EDS) and elemental mapping, band gap energy and X-ray photoelectron spectroscopy (XPS). The optimal experimental conditions were investigated and determined to be pH 3.0, 0.5 g L −1 of catalyst and 2.5 mmol L −1 of H 2 O 2 . A decolorization efficiency of 93.3% was achieved in 60 min of reaction and a TOC removal of 92.3% was reached in 180 min. The stability and recycle capacity of FeIn 2 S 4 indicated that the catalyst can be used more than four times without considerable loss of efficiency. Free radicals investigation revealed that • OH and O 2•− radicals were the major oxygen reactive species involved on Ponceau 4R degradation. The lower-mass intermediates from Ponceau 4R degradation were identified, and a mechanism for the photo-Fenton treatment was suggested. Therefore, the composite showed a performance that makes it a promising catalyst for removing emerging contaminants in water.

“…FeIn 2 S 4 NCs were prepared by means of a hydrothermal reaction method described in a previous study . As‐synthesized nanoparticles were cleaved into smaller size via sonication with N ‐methyl‐2‐pyrrolidone (NMP), such that charge transport was not hindered due to large interparticle distance but a densely packed film was formed ( Figure a and Figure S2 (Supporting Information)).…”

“…Materials : A previously reported procedure was followed to synthesize FeIn 2 S 4 microspheres . Because the size and morphology of the resulting materials was not yet suitable for use in the FET channel layer, the microspheres were cleaved and isolated by means of lengthy sonication in the solution phase (Figure S2, Supporting Information).…”

FeIn₂S₄ Nanocrystals: A Ternary Metal Chalcogenide Material for Ambipolar Field‐Effect Transistors

et al. 2018

View full text Add to dashboard Cite

An ambipolar channel layer material is required to realize the potential benefits of ambipolar complementary metal–oxide–semiconductor field‐effect transistors, namely their compact and efficient nature, reduced reverse power dissipation, and possible applicability to highly integrated circuits. Here, a ternary metal chalcogenide nanocrystal material, FeIn2S4, is introduced as a solution‐processable ambipolar channel material for field‐effect transistors (FETs). The highest occupied molecular orbital and the lowest unoccupied molecular orbital of the FeIn2S4 nanocrystals are determined to be −5.2 and −3.75 eV, respectively, based upon cyclic voltammetry, X‐ray photoelectron spectroscopy, and diffraction reflectance spectroscopy analyses. An ambipolar FeIn2S4 FET is successfully fabricated with Au electrodes (E F = −5.1 eV), showing both electron mobility (14.96 cm2 V−1 s−1) and hole mobility (9.15 cm2 V−1 s−1) in a single channel layer, with an on/off current ratio of 105. This suggests that FeIn2S4 nanocrystals may be a promising alternative semiconducting material for next‐generation integrated circuit development.

The ternary iron-group thiospinels of metal diindium sulfides (MIn S , M=Fe, Co, Ni) with a vertically aligned nanosheet array structure are fabricated through an in situ solvothermal method on F-doped tin oxide (FTO) substrates, which are employed as one type of platinum (Pt)-free counter electrodes (CEs) in structure-dependent dye-sensitized solar cells (DSSCs). A DSSC assembled with ternary CoIn S CE achieves an photoelectric conversion efficiency (PCE) of 8.83 %, outperforming than that of FeIn S (7.18 %) and NiIn S (8.27 %) CEs under full sunlight illumination (100 mW cm , AM 1.5 G), which is also comparable with that of the Pt CE (8.19 %). Putting aside that the interconnected nanosheet array provides fast electron transfer and electrolyte diffusion channels, the highest PCE of CoIn S based DSSC results from its largest specific surface area (144.07 m g ), providing abundant active sites and the largest electron injection efficiency from CE to electrolyte.
