2D materials, namely thin layers of layered materials, are attracting much attention because of their unique electronic, optical, thermal, and catalytic properties for wide applications. To advance both the fundamental studies and further practical applications, the scalable and controlled synthesis of large-sized 2D materials is desired, while there still lacks ideal approaches. Alternatively, the chemical vapor transport reaction is an old but powerful technique, and is recently adopted for synthesizing 2D materials, producing bulk crystals of layered materials or corresponding 2D films. Herein, recent advancements in synthesizing both bulk layered and 2D materials by chemical vapor transport reactions are summarized. Beginning with a brief introduction of the fundamentals of chemical vapor transport reactions, chemical vapor transport-based syntheses of bulk layered and 2D materials, mainly exampled by transition metal dichalcogenides and black phosphorus, are reviewed. Particular attention is paid to important factors that can influence the reactions and the growth mechanisms of black phosphorus. Finally, perspectives about the chemical vapor transport-based synthesis of 2D materials are discussed, intending to redraw attentions on chemical vapor transport reactions.
二维材料，即层状材料的薄层，因其独特的电子、光学、热学和催化性能而备受关注，具有广泛的应用前景。为了推动基础研究和进一步的实际应用，人们期望能够实现大尺寸二维材料的可扩展且可控合成，但目前仍缺乏理想的方法。化学气相传输反应是一种古老但强大的技术，最近被用于合成二维材料，制备层状材料的块状晶体或相应的二维薄膜。本文总结了通过化学气相传输反应合成块状层状材料和二维材料的最新进展。首先简要介绍化学气相传输反应的基本原理，然后回顾以过渡金属二硫属化物和黑磷为例的基于化学气相传输的块状层状材料和二维材料的合成方法。特别关注了影响反应和黑磷生长机制的重要因素。最后，讨论了基于化学气相传输的二维材料合成的前景，旨在重新引起人们对化学气相传输反应的关注。
