Preparation, Characterization, and Applications of Transition Metal Dichalcogenides Nanoscrolls: Recent Development and Prospects

Two-dimensional (2D) transition metal dichalcogenide (TMDC) nanoscrolls have attracted significant attention in recent years owing to their fascinating properties, including high specific surface area, unique electronic structure, and excellent optoelectronic performance. These properties arise from their intrinsic one-dimensional (1D) spiral scroll geometry. In this review, we systematically present the preparation methods, properties, and applications of TMDC nanoscrolls. For fabrication, we detail a variety of preparation strategies, both on substrates and in solution. Next, we discuss the characterization and physical properties of TMDC nanoscrolls. Finally, we summarize their applications in photodetection, the hydrogen evolution reaction (HER), optoelectronic synapses, and other related fields.
