摘要
The research in two-dimensional(2D)materials has flourished since the pioneer work on graphene in 2004.Many unprecedented properties have been discovered in 2D materials,enabling their high performances in(opto-)electronics,catalysis and biomedicine.As the family of 2D materials continues to grow and more 2D members are being identified,it is timely and important to summarize the recent progress of 2D materials,and look forward to their further advances and developments not only in fundamental studies but also in various applications.
