In this talk, I will summarize the recent research on synthesis, characterization and applications of two-dimensional nanomaterials in my group. I will introduce the synthesis and characterization of novel low-dimensional nanomaterials, such as graphene-based composites including the first-time synthesized hexagonal-close packed (hcp) Au nanosheets (AuSSs) on graphene oxide,surface-induced phase transformation of AuSSs from hcp to face-centered cubic (fcc) structures, the synthesis of ultrathin fccAu@Pt and Au@Pd rhombic nanoplates through the epitaxial growth of Pt and Pd on the hcpAuSSs, respectively,the first-time synthesis of 4H hexagonal phase Au nanoribbons (NRBs)and their phase transformation to fccAu RNBs as well as the epitaxial growth of Ag, Pt and Pd on 4H Au NRBs to form the 4H/fccAu@Ag, Au@Pt and Au@Pd core–shell NRBs, and the epitaxial growth of metal and semiconductor nanostructures on solution-processabletransition metal dichalcogenide (TMD)nanosheesat ambient conditions, single- or few-layer metal dichalcogenidenanosheetsand hybrid nanomaterials, the large-amount, uniform, ultrathin metal sulfideand selenide nanocrystals, other 2D nanomaterials, nanodots prepared from 2D nanomaterials, and self-assembled 2D nanosheets andchiral nanofibers from ultrathin low-dimensional nanomaterials.Then I will demonstrate the applications of these novel nanomaterials in chemical and bio-sensors, solar cells, water splitting, hydrogen evolution reaction, electric devices, memory devices, conductive electrodes, other clean energy, etc.
