“…As shown in Figure c, the Sn 3d spectra displayed two typical peaks at 486.6 and 495.0 eV, which correspond to the binding energies of Sn 3d 5/2 and Sn 3d 3/2 , respectively . 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 .…”

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.

SnS /graphene composites have attracted extensive attention in energy storage owing to their excellent electrochemical performance. However, most of the previous methods to synthesize SnS /graphene composites require long times, high temperatures, or high pressures, which are obstacles for practical low-cost production. A simple one-pot strategy to prepare SnS /graphene composites has been developed, which is not time-consuming (1 h) and requires moderate temperature (75 °C) in atmosphere. Through this method, ultrafine SnS nanoparticles anchored on graphene nanosheets are prepared and exhibit excellent electrochemical performance for both lithium and sodium storage. Specifically, as anodes for lithium-ion batteries, the SnS /graphene electrode delivers a high capacity of 1480 mAh g after 50 cycles at 0.2 A g . Even at 10 A g , the SnS /graphene electrode can achieve a capacity of 666 mAh g . A constructed full lithium-ion cell exhibits a capacity of 957 mAh g after 50 cycles at 1 A g . This simple one-pot strategy may pave the way for large-scale production and practical application of SnS /graphene composites in energy storage.
