Abstract
Two-dimensional (2D) materials have been attracting extensive interest due to their remarkable chemical, optical, electrical, and magnetic properties, making them ideal candidates for a broad range of applications. Developing facile synthesis methods that can fabricate high-quality 2D materials in an efficient, scalable, and cost-effective way is essential. Among the emerging techniques, salt-assisted methods to synthesize 2D materials, including molten salt method, salt-assisted chemical vapor deposition, and salt-template method, has demonstrated significant potential in fulfilling these requirements. This review highlights recent advancements in the synthesis of 2D materials through salt-assisted methods, focusing on their preparation processes and wide-ranging applications. It also explores the role of salts, in various forms, in directing the formation of 2D structures, providing insights for strategic synthesis design. Finally, challenges and future directions in salt-assisted synthesis are discussed, emphasizing strategies to enable controllable, high-yield production of 2D materials.
