NOVELTY - Preparing graphene involves dissolving saccharide and metal nitrate hydrate in deionized water solvent and treating hydrothermally at 150-300 degrees C for 0.1-3 hours to obtain fluffy solid product. The obtained fluffy solid product is ground into powder to obtain carbon template material, where mass ratio of metal nitrate, sugar and hydrate are 0.1-2:0.5-3. The obtained template carbon material is carbonized at 300-1000 degrees C for 1-6 hours in presence of inert gas atmosphere to obtain graphene material. The template is removed by acid solution, then washed and dried to obtain graphene. USE - Method for preparing graphene (claimed). ADVANTAGE - The method enables to prepare graphene in simple and eco friendly manner which is suitable for industrial production.
