Electrochemical synthesis of 2D antimony, bismuth and their compounds
Two-dimensional (2D) group-VA layered nanomaterials have broad application prospects due to their unique physical and chemical properties and functional structures and have received increasing attention in recent years. Compared with phosphorene and arsenene, 2D antimony, bismuth and their compounds have excellent physical and chemical properties, giving them broad application prospects in important and widespread research fields. The mass production of high-purity or special-function 2D antimony, bismuth and their compounds is important to promoting basic research and industrial applications. Amongst the most advanced synthetic methods at present, electrochemical exfoliation is a promising method, which has low cost, environmentally friendly, simple operation and instruments, and mild conditions. In this work, we briefly reviewed recent research progress in the preparation of 2D antimony, bismuth and their compounds by electrochemical exfoliation depending on the direction of the exfoliating voltage. Furthermore, we discussed the possible peeling mechanisms and potential applications of different peeling methods in detail. Finally, the development trends, challenges and opportunities of the technology for the preparation of 2D antimony, bismuth and their compounds by electrochemical exfoliation that have emerged in future were outlined.
