Molybdenum-doped few-layered SnS2 architectures with enhanced electrochemical supercapacitive performance

Molybdenum doped few-layered SnS2 (m-SnS2) architectures have been fabricated via a facile hydrothermal route. The results indicate that the resultant m-SnS2 is composed of numerous few-layered nanosheets and possesses a hierarchical architecture with mesoporous features. When evaluated as an electrode material for supercapacitors, the m-SnS2 architecture exhibits obviously enhanced electrochemical performance with high specific capacitance, good cycling stability and rate capability in comparison with the bare SnS2 sample. It is believed that the superior electrochemical properties can be attributed to the robust mesoporous architectures with large surface area, the few-layered nature as well as other positive factors such as expanded interlayer space and rich dislocations which originate from the molybdenum doping.
