Claim Text:
1. A process for producing a two-dimensional nanomaterial comprising: (a) adding at least one sol precursor compound selected from the group consisting of metal halides, metal nitrates, metal carboxylates, metal oxysulfates, metal acetylacetonates and metal alkoxides and also waterglass for Si, wherein the metal is selected from the group consisting of Zn, Mg, Al, Y, Fe, Cr, Co, Si, Zr, Ti, Ce, Mo, W and Hf to (b) reacting mixture (a) in a sol/gel process to form gel from the at least one sol precursor compound on the graphene oxide particles or, respectively, the graphene particles, (c) removing the at least one surfactant, and (d) optionally heating the gel-coated graphene oxide particles for at least 1 min to at least 500° C. under inert gas atmosphere to reduce the graphene oxide to graphene, wherein the two-dimensional nanomaterial produced is confined in a third dimension to a range of 0.3 nm to 500 nm including any coating.
