NOVELTY - Method of manufacturing graphene nanoribbons, involves preparing substrate, preparing nanowire comprising graphite and catalyst, arranging graphite on nanowire, arranging the obtained nanowire on substrate which acts as a carbon source, drying the mixture, and separating obtained graphene nanoribbons. USE - The method is useful for manufacturing graphene nanoribbons which is used in hydrogen reservoir and electrical device (all claimed). ADVANTAGE - The method is inexpensive and enables mass production of graphene nanoribbon.
