METHOD FOR PREPARING EXPANDED HEXAGONAL BORON NITRIDE BY TEMPLATING

Abstract:

In an embodiment, a method for preparing expanded hexagonal boron nitride comprises mixing a boron compound and a carbon template in an organic solvent; removing the organic solvent to provide a dried mixture of the boron compound and the carbon template; exposing the dried mixture to a nitrogen-containing gas under conditions effective to provide a crude product comprising hexagonal boron nitride; removing the carbon template from the crude product to provide the expanded hexagonal boron nitride.
