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.

二维二硫化钼（2D MoS ₂）由于其独特的结构和性能而被认为是许多应用中有希望的候选物。然而，大规模和高质量的2D 1T相MoS ₂的可控合成仍然是一个挑战。本文中，我们通过使用K ₂ SO ₄盐作为同时的高温硫源和模板，提出了从2H到1T @ 2H相的可扩展和可控制的2D MoS ₂合成。合成后的1T @ 2H-2D MoS ₂具有很高的产率，可以在LiClO _4中以1 mV / s的扫描速率容易地组装成具有434 F / g高比电容的独立电极。碳酸亚乙酯/碳酸二甲酯（EC / DMC）。此外，可以使用该方法合成各种单晶2D过渡金属硫化物（WS ₂，PbS，MnS和Ni ₉ S ₈）和2D S掺杂的碳。我们相信，这项研究可能为可扩展且可控的2D MoS ₂以外的其他2D材料合成提供新的视野。
