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.
Claims19
A process for making carbon nanosheet material, said process comprising the steps of:
- providing a renewable carbohydrate source to a reactor comprising a solvent to obtain a soaked or dissolved carbohydrate source;
- adding a dehydration solution and a catalyst to the reactor comprising the soaked or dissolved carbohydrate source to obtain a reaction mixture, where
- the dehydration solution has a hydrogen ions concentration of at least approximately 1%, and
- the catalyst is chosen from the group consisting of platinum, palladium, LiAlH4, nickel, yeast, aluminum-nickel alloy, cobalt, B2H6, zinc, NaBH4, and copper;
- charging said reactor with air or inert gas;
- heating the reaction mixture to remove glycosidic linkages and water molecules from the carbohydrate thereby producing an intermediate mixture with sheet-like morphology;
- and
- further heating the intermediate mixture in inert gas to form a network of the carbon nanosheet material, wherein the carbon nanosheet material is in a particulate form, porous foam form, or dispersed in a solvent.
