英文摘要：

Two-dimensional atomic crystals have recently drawn intense attentions due to their unique 2D planar structure, novel properties and attractive applications. In this review, we summarized the recent advances on the synthesis of 2D transition metal dichalcogenides（TMDCs） by chemical vapor deposition（CVD） with the emphasis on 2D Mo S2 and WS2. We discussed the effects of various growth parameters on the synthesis of 2D Mo S2 and WS2. We also covered the synthesis strategies for the growth of binary alloys and heterostructures based on Mo X2 and WX2（X=S, Se）. Finally, we discussed the challenges and opportunities for the CVD growth of 2D TMDCs.
