摘要
Two-dimensional molybdenum disulfide(2D MoS_(2))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 MoS_(2)is still a challenge.Herein,we present the scalable and controllable synthesis of 2D MoS2 from 2H to 1T@2H phase by using K_(2)SO_(4)salt as a simultaneous high-temperature sulfur source and template.The as-synthesized 1T@2H-2D MoS_(2)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 LiClO_(4)ethylene carbonate/dimethyl carbonate(EC/DMC).Moreover,various single-crystal 2D transition metal sulfides(WS_(2),PbS,MnS and Ni_(9)S_(8))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 MoS_(2).
