In recent years,molybdenum disulfide(MoS2)has gained significant attention in the scientific community.Few-layered MoS2 demonstrates unique properties and potential applications.However,the synthesis of few-layered and high-purity 1T-MoS2 is still a challenge.In this study,we successfully employed a hydrothermal method to synthesize few-layered and high-purity 1T-MoS2.The purity of the material is controlled by a combination of sodium borohydride and ethanol.Notably,the few-layered 1T-MoS2 exhibits exceptional performance as a supercapacitor,including the high specific capacitance(250.3 F g-1 at a current density of 1 A g-1)and excellent long-trem cycling stability(90.7%after 5000 cycles).Meanwhile,the asymmetric device assembled by 6-FL-1T-MoS2 and active carbon on carbon cloths exhibits excellent flexibility and high energy and power density(23.1 μWh cm-2 at 600 μW cm-2,55 μWh cm-2 at 12000 μW cm-2).This work provides valuable insights into the synthesis of few-layered and high-purity 1T-MoS2,opening up new avenues for further research and applications.
