Methods for preparing alkali metal-intercalated hexagonal boron nitride materials, resultant products and uses thereof

Abstract

Embodiments relate to the field of hexagonal boron nitride (hBN). In particular, to an alkali metal (A) intercalated hBN material. The A-intercalated hBN is chemically active, electrically conducting, and superconducting. The A-intercalated hBN is spontaneously soluble in aprotic organic solvents to form dispersions of exfoliated reduced 2-dimensional hBN sheets in organic solvents. The dispersions of exfoliated reduced 2-dimensional hBN materials in organic solvents materials can be reacted with metal salts to form 2-dimensional hBN-supported metal and/or metal oxide nanoparticle composites. The solutions/dispersions of exfoliated reduced 2-dimensional hBN materials in organic solvents can be transferred to water or organic solvents to form stable aqueous and organic suspensions of 2-dimensional hBN.
