Abstract
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.
