“…It is reported [31] that high surface area of mesoporous particles shows good performance as a catalyst. It is also reported [32] that due to intrinsic layer crystal structure of SnS with controlled morphologies it possess high surface area, has greater accessibility to the electrolyte, faster transportation of ions, and accelerated phase transition. But in our case the surface area is much lower than that of the reported value [32] for SnS, which support the CV results, that SnS is not prominent electrocatalyst for the reduction of I 3 − .…”

“…Several groups have previously used TEM to identify the crystal structure of SnS nanoparticles (Lu et al, 2015;Tarkas et al, 2017), nanosheets (Hori et al, 2014;Brent et al, 2015;Yang et al, 2015;Chao et al, 2016), nanorods (Suryawanshi et al, 2014;Chauhan et al, 2015) and micron-sized flakes (Xia et al, 2016;Tian et al, 2017) which were synthesised through various techniques. The TEM characterisation of the SnS nanosheets and flakes have been generally limited to plane view analysis and basic d-spacing measurements in cross section in order to confirm the phase of the material.…”

Summary The crystal and defect structure of SnS crystals grown using chemical vapour deposition for application in electronic devices are investigated. The structural analysis shows the presence of two distinct crystal morphologies, that is thin flakes with lateral sizes up to 50 μm and nanometer scale thickness, and much thicker but smaller crystallites. Both show similar Raman response associated with SnS. The structural analysis with transmission electron microscopy shows that the flakes are single crystals of α‐SnS with [010] normal to the substrate. Parallel with the surface of the flakes, lamellae with varying thickness of a new SnS phase are observed. High‐resolution transmission electron microscopy (TEM), scanning transmission electron microscopy (STEM), first‐principles simulations (DFT) and nanobeam diffraction (NBD) techniques are employed to characterise this phase in detail. DFT results suggest that the phase is a strain stabilised β’ one grown epitaxially on the α‐SnS crystals. TEM analysis shows that the crystallites are also α‐SnS with generally the [010] direction orthogonal to the substrate. Contrary to the flakes the crystallites consist of two to four grains which are tilted up to 15° relative to the substrate. The various grain boundary structures and twin relations are discussed. Under high‐dose electron irradiation, the SnS structure is reduced and β‐Sn formed. It is shown that this damage only occurs for SnS in direct contact with SiO2.

“…Electrochemical measurements including CV, GCD, and EIS were measured using a Biologic-SP150 workstation. CV was conducted at various scan rates (10,20,30,40, and 50 mV s −1 ) between 0.1 to −0.6 V vs. Ag/AgCl. The GCD test was conducted between −0.1 to 0.4 V with different current densities to calculate the specific capacitance.…”

Abstract:A cost-effective and uniform crystal with different structures was fabricated using a facile chemical bath deposition technique for electrochemical supercapacitor (SC) applications. In this study, CuS, PbS, and CuS@PbS composite electrodes were fabricated for SCs. The morphology and structure of the electrodes were analyzed by field emission-scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy. The CuS@PbS composite electrode delivered outstanding electrochemical performance in SCs with a high specific capacitance of 1004.42 F g −1 at a current density of 2.85 A g −1 , good cycling stability (only 2.9% loss after 3000 cycles at 2.85 A g −1 ), higher energy density of 33.89 Wh kg −1 at a power density of 714.28 W kg −1 , and an excellent rate capability compared to other electrodes. These results show that the CuS@PbS composite can be used to improve the surface morphology and is a promising positive electrode material for SC applications.
