Facile Synthesis of SnS(2) Nanostructures with Different Morphologies for High-Performance Supercapacitor Applications

[Image: see text] SnS(2) is an emerging candidate for an electrode material because of the considerable interlayer spaces in its crystal structures and the large surface area. SnS(2) as a photocatalyst and in lithium ion batteries has been reported. On the other hand, there are only a few reports of their supercapacitor applications. In this study, sheetlike SnS(2) (SL-SnS(2)), flowerlike SnS(2) (FL-SnS(2)), and ellipsoid-like SnS(2) (EL-SnS(2)) were fabricated via a facile solvothermal route using different types of solvents. The results suggested that the FL-SnS(2) exhibited better capacitive performance than the SL-SnS(2) and EL-SnS(2), which means that the morphology has a significant effect on the electrochemical reaction. The FL-SnS(2) displayed higher supercapacitor performance with a high capacity of approximately ∼431.82 F/g at a current density of 1 A/g. The remarkable electrochemical performance of the FL-SnS(2) could be attributed to the large specific surface area and better average pore size. These results suggest that a suitable solvent is appropriate for the large-scale construction of SnS(2) with different morphologies and also has huge potential in the practical applications of high-performance supercapacitors.
