“…This is in agreement with previous reports for Sn 4+ . These two peaks are clearly separated by the splitting energy of ≈8.4 eV, which is the representative value of Sn 4+ in SnS 2 . For the S element (Figure d), the high‐resolution XPS spectra displayed two spin–orbital coupling peaks centered at 162.7 and 161.5 eV, and these are characteristics for the 2p 1/2 and 2p 3/2 core levels, respectively .…”

Recent advances in 2D transition metal dichalcogenides (TMDs) have led to a variety of promising technologies for nanoelectronics, photonics, sensing, energy storage, and optoelectronics. Among these dichalcogenides, tin sulfide (SnS2) has received great attention due to its high optical absorption coefficient, high theoretical capacitance, high natural abundance of precursor chemicals, and minimal impact of these on the environment (green chemistry). It is crucial to obtain materials with varied morphologies because the chemical and physical properties are dependent on the morphology. The controlled synthesis of SnS2 with a specific morphology, a hollow sphere, is of significant interest. Herein, a facile, template‐free, one‐step solvothermal method to prepare SnS2 spheres with a hollow structure is demonstrated. The size of the SnS2 hollow spheres is uniform, at 2 μm in diameter, and the walls of the sphere are only 300 nm thick. The hollow structure forms due to the different specific surface energies of the SnS2 sheets and the fluorine‐doped tin oxide (FTO) substrate. Furthermore, the possible growth mechanism of these SnS2 hollow spheres is proposed, which may be applied to other 2D TMD systems.

“…These include doping with metal or non-metal ions, use of a carbon matrix and material engineering into nanostructured forms of tin sulfides and their nanocomposites to apply them as electrochemical capacitors (Mishra et al 2017;Wang et al 2015b). Recently, Parveen et al (2018) synthesized SnS 2 in different shapes of nanostructures like; ellipsoid tin sulfide (EL-SnS 2 ), flower-like (FL-SnS 2 ), and sheet-like (SL-SnS 2 ). The flower-like tin sulfide was the most promising one with small pore size and larger surface area exhibiting 432 F g −1 of specific capacitance at 1 A g −1 .…”

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

et al. 2020

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.

“…Among them, tin disulfide (SnS 2 ) as a typical 2D layered material with weak van der Waals interaction between the layers has attracted extensive attention for pseudocapacitor materials. Parveen et al fabricated SnS 2 nanostructure with different morphologies via a facile solvothermal route using different types of solvents. The flower‐like SnS 2 exhibited a related high specific capacitance of about 431.82 F/g at the current density of 1 A/g.…”

Two‐dimensional (2D) SnS2/MoS2 heterojunction with a 2D/2D novel structure was used as electrode material for enhanced supercapacitor performance. Compared with the sole SnS2, the as‐prepared 2D/2D SnS2/MoS2 layered heterojunction has exhibited great improvement in supercapacitor properties. This novel structure can effectively prevent agglomeration and stacking in electrochemical process, and 2D/2D structure is beneficial to intercalation and desorption of ions in electrochemical processes. The experiment result shows that MoSn5 (samples with 5% MoSn5 mole ratios) display a specific capacitance of 466.6 F/g at the current density of 1 A/g in 0.5 mol/L potassium hydroxide solution, an impressive cycling stability with 88.2% capacitance retention at current density of 4 A/g. In addition, the as‐fabricated symmetric supercapacitor exhibited high energy density of 115 Wh kg−1 at the power density of 2230 Wh kg−1. This work provides a fundamental investigation of 2D/2D layered material synergistic effect on the electrochemical process.
