“…After the emergence of novel 2D materials and improved production methods such as chemical vapor deposition and chemical and mechanical exfoliation, thinner structures of SnS 2 were synthesized for different applications. For example, a few nanometers thick hexagonal SnS 2 was used for lithium storage in battery applications [35][36][37][38]. To enhance the electrochemical performance, composite forms of SnS 2 with graphene were examined [39][40][41][42][43].…”

Employing density functional theory-based methods, we investigate monolayer and bilayer structures of hexagonal SnS 2 , which is a recently synthesized monolayer metal dichalcogenide. Comparison of the 1H and 1T phases of monolayer SnS 2 confirms the ground state to be the 1T phase. In its bilayer structure we examine different stacking configurations of the two layers. It is found that the interlayer coupling in bilayer SnS 2 is weaker than that of typical transition-metal dichalcogenides so that alternative stacking orders have similar structural parameters and they are separated with low energy barriers. A possible signature of the stacking order in the SnS 2 bilayer has been sought in the calculated absorbance and reflectivity spectra. We also study the effects of the external electric field, charging, and loading pressure on the characteristic properties of bilayer SnS 2 . It is found that (i) the electric field increases the coupling between the layers at its preferred stacking order, so the barrier height increases, (ii) the bang gap value can be tuned by the external E field and under sufficient E field, the bilayer SnS 2 can become a semimetal, (iii) the most favorable stacking order can be switched by charging, and (iv) a loading pressure exceeding 3 GPa changes the stacking order. The E-field tunable band gap and easily tunable stacking sequence of SnS 2 layers make this 2D crystal structure a good candidate for field effect transistor and nanoscale lubricant applications.

“…Typically, four reduction peaks can be found in cathodic scans from the CV curves. The reduction peak at 1.83 V (vs. Li/Li + ) is known to arise from the lithium intercalation into SnS 2 without a phase decomposition (Equation (1)) [29,30]. The reduction peaks at 1.62 and 1.19 V (vs. Li/Li + ) in the first cathodic sweep could be attributed to the decomposition of SnS 2 into metallic tin and the formation of Li 2 S (Equation (2)), which may occur in three steps [30], as well as the formation of a solid electrolyte interface (SEI) [11,31].…”

The peak at 0.22 V (vs. Li/Li + ) in the first anodic scan corresponds to the reversible formation of Li x Sn alloy (Equation (3)) and the oxidation peak at 0.50 V (vs. Li/Li + ) in the first anodic scan possibly originates from the delithiation reaction of Li x Sn alloy (Equation (3)).…”

Abstract.A novel multiwall carbon nanotubes wrapped nanoflake-like SnS 2 (MWCNTs-SnS 2 ) composite was designed by simply mixing carbon nanotubes with nanoflake-like SnS 2 . The fabricated MWCNTs-SnS 2 composite material was characterized using scan electron microscopy and transmission electron microscopy. The MWCNTs-SnS 2 was used to modify glassy carbon electrode to examine the electrocatalysis of hydrogen peroxide and oxygen. Moreover, direct electrochemistry of glucose oxides immobilized on MWCNTs-SnS 2 modified electrode was investigated. This MWCNTs-SnS 2 composite provided a promising approach to fabricate electrochemical sensor.
