Molten-salt assisted synthesis of two-dimensional materials and energy storage application

Due to their unique structure and physicochemical properties, two-dimensional (2D) materials demonstrate great potential for energy storage applications. These materials are highly efficient in energy storage and are environmentally friendly. However, 2D materials industrial applications are limited by conventional synthesis, making it difficult to achieve large-scale and high-quality yields. Molten-salt assisted synthesis (MSAS) has been considered an environmentally friendly and highly efficient method of producing 2D materials. This work briefly reviews recent advances in 2D materials synthesis by the molten salt method, including transition metal binary compounds, MXenes, perovskite and other 2D materials. In addition, synthesized 2D materials are investigated for use in batteries, supercapacitors, and catalysis. Finally, we provide fundamental guidance for the synthesis of controllable 2D materials through the prospect of the molten salt method.
