Abstract: Lamellar transition-metal dichalcogenides (MX2) have promising applications in electrochemical energy storage and conversion devices due to their two-dimensional structure, ultrathin thickness, large interlayer distance, tunable bandgap, and transformable phase nature. Interlayer engineering of MX2 nanosheets with large specific surface area can modulate their electronic structures and interlayer distance as well as the intercalated foreign species, which is important for optimizing their performance in different devices. In this talk, we will summarize our recent works on interlayer engineering of MoS2, MoSe2 and MoS2xSe2(1-x) nanosheets and their applications for sodium ion battery and photocatalytic hydrogen generation.
