Grephene has superior properties such as high electric conductivity and higher specific area from the atomically thin structures. Many methods have been presented to synthesize graphene, and the most common method to produce graphene is oxidation/reduction from natural graphite. However, this approach mainly uses strong acid and harsh reducing agent such as hydrazine; therefore these conditions cause many defects on the surface of graphene. Recently, some researchers have introduced new ways to synthesize graphene without redox system for good-quality graphene. Supercritical fluid (SCF) is a promising material for intercalating agent of graphite owing to their low viscosity and high permeability. In this study, we introduce a one-step method to produce metal oxide-decorated exfoliated graphene nanosheets via supercritical fluid processes for supercapacitor applications. We observed morphology of those nanostructures with SEM and also measured electrical properties. |
