Two-dimensional (2D) antimonene has triggered a wide range of interest owing to its unique structure and physical properties. Van der Waals heterostructures, which integrate two or more different materials with weak interactions between the layers, offer more degrees of freedom for designing functional materials. Very recently, 2D antimonene-based van der Waals heterostructures have inspired extensive research enthusiasm in various fields. Here, we systematically summarize the band alignment types and regulation strategies of interfacial properties for 2D antimonene-based heterostructures and the state-of-the-art current applications, including electronic and optoelectronic devices, catalysis, energy storage, and the biomedical field. Finally, we discuss the opportunities and challenges and put forward the prospects of 2D antimonene-based heterostructures. [ABSTRACT FROM AUTHOR]
