Abstract
This patent disclosure includes a process that uniquely and unexpectedly results in the production of extremely high specific surface area and large pore volume carbon nanomaterial with high content of sp2 hybridized carbon-carbon in the form of nanosheets from a renewable carbonaceous raw material. The resulting nanomaterial is in particulate form or porous nanomaterial or dispersed in solvent. This process can also be used to produce carbon nanosheet on substrates or form a nanocomposite with other materials that results in exceptional properties.

A process for making a nanocomposite material, said process comprising:
- combining a renewable carbohydrate source with a dehydration solution and a catalyst chosen from the group consisting of platinum, palladium, LiAlH4, nickel, yeast, aluminum-nickel alloy, cobalt, B2H6, zinc, NaBH4, and copper to obtain a reaction mixture, where the dehydration solution has a hydrogen ions concentration of at least approximately 1%;
- heating the reaction mixture to remove glycosidic linkages and water molecules from the carbohydrate thereby producing an intermediate mixture with a fused sheet-like morphology;
- heating the intermediate mixture in the presence of gaseous hydrogen at a temperature in the range of approximately 500 to 1500° C. to form a carbon nanosheet material in the form of a powder;
- and
- providing the carbon nanosheet material to a polymer to obtain the nanocomposite material.
