Abstract
A template-assisted method for the synthesis of 2D nanosheets comprises growing a 2D material on the surface of a nanoparticle substrate that acts as a template for nanosheet growth. The 2D nanosheets may then be released from the template surface, e.g. via chemical intercalation and exfoliation, purified, and the templates may be reused.
Claims18
A composition of matter comprising:
- a nanoparticle template comprising a material having a first crystal structure;
- and
- a two-dimensional (2D) transition metal dichalcogenide nanosheet at least partially covering a surface of the nanoparticle template, the two-dimensional (2D) transition metal dichalcogenide nanosheet comprising a material having a second crystal structure,
- wherein the first crystal structure and the second crystal structure exhibit therebetween a lattice mismatch of around 5% or less.
