Abstract

The invention provides a method for the production of graphene-structured products. The method generally comprises contacting at a conversion temperature ranging from about 850° C. to about 1100° C. in an inert atmosphere coal with a molten salt to produce a graphene-structured product. In an alternate embodiment, the method comprises contacting at a conversion temperature ranging from about 850° C. to about 1100° C. in an inert atmosphere coal with a molten salt to produce a graphene-structured product; and, separating a rare earth element from the graphene-structured product.
