| Popis: | Two-dimensional molybdenum disulfide (2D MoS2) is considered as a promising candidate for many applications due to its unique structure and properties. However, the controllable synthesis of large-scale and high-quality 2D 1T-phase MoS2 is still a challenge. Herein, we present the scalable and controllable synthesis of 2D MoS2 from 2H to 1T@2H phase by using K2SO4 salt as a simultaneous high-temperature sulfur source and template. The as-synthesized 1T@2H-2D MoS2 exhibits a high yield and can be easily assembled into freestanding electrode with high specific capacitance of 434 F/g at a scan rate of 1 mV/s in LiClO4 ethylene carbonate/dimethyl carbonate (EC/DMC). Moreover, various single-crystal 2D transition metal sulfides (WS2, PbS, MnS and Ni9S8) and 2D S-doped carbon can be synthesized using this method. We believe that this study may provide a new sight for scalable and controllable synthesis of other 2D materials beyond 2D MoS2. |
