Selective synthesis of Sb2S3 nanostructures with different morphologies for high performance in dye-sensitized solar cells

Atomically isolated and unsaturated Sb sites created on Sb2S3for highly selective NO electroreduction to NH3

“…S1 †) shows two peaks of S2p 1/2 (163.6 eV) and S2p 3/2 (161.8 eV), in good accordance with those reported for Sb 2 S 3 . [42][43][44] We employ X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) characterizations to further examine the valence states and coordination structures of Sb 2 S 3 . The Sb K-edge XANES spectra (Fig.…”

Fabrication of Sb2S3 Thin Films by Low-Temperature Plasma-Sulfurizing Metallic Sb Layers

“…Oxygen was not detected, but a small amount of carbon was used for calibration (284.80 eV for C 1s) and was detected in the Sb MNN Auger spectrum at 1030.36 eV . With curve fitting, Sb 3d 5/2 of 529.877 eV and Sb 3d 3/2 of 539.077 eV corresponded to Sb 3+ , and S 2P 3/2 of 161.677 eV and S 2P 1/2 of 162.877 eV corresponded to S. − Compared with pure Sb and S, the binding energy of Sb shifts about 1.577 eV to the higher range and the binding energy of S shifts to 2.323 eV to the lower range. The binding energy shift indicates the charge transfer from antimony to sulfur .…”

“…Since then, Sb 2 S 3 thin-film solar cells have been extensively studied, and the preparation methods have become diversified. Considerable efforts have been devoted to improving the performance of Sb 2 S 3 thin-film solar cells using methods such as CBD, successive ionic layer adsorption and reaction (SILAR), atomic layer deposition (ALD), rapid thermal evaporation (RTE), hydrothermal, spin-coating, and magnetron sputtering . Among them, the CBD and SILAR methods cannot avoid the introduction of Sb 2 O 3 and SbOCl impurities, which reduces device performance.…”

The study of the applicability of invar nanostructures for the reduction of p-nitrophenyl compounds

“…Moreover, unlike noble nanocatalysts based on platinum, gold or silver, nanostructured catalysts based on base metals such as copper, iron, cobalt, nickel, etc. have a higher productivity and surface selectivity, and the possibility of phase transformations with the formation of oxide phases in the surface layer can significantly increase the productivity of the catalysts [5][6][7][8]. The presence of a complex phase structure and a large number of grain boundaries for nanostructures serves as additional catalytic centers that make it possible to accelerate the reduction process, without forming agglomerates, which leads to an increase in the operating life [9,10].…”
