| Popis | In this study, electrochemical hydrogen storage properties of graphene coatings were investigated. X-ray diffraction, Raman spectroscopy, field emission scanning electron microscopy, and galvanostatic charge/discharge measurements were used to characterize the materials properties. Graphene oxide was prepared using a modified Hummers method. A graphene coating was fabricated by electrophoretic deposition. Results showed that a graphene-coated copper electrode, as a low-cost and low-weight electrode, has a good charge/discharge capacity that makes it a promising candidate for electrochemical hydrogen storage applications. The highest discharge capacity obtained for a coated electrode was 45 mA h g(-1), while the discharge capacity of a bare copper electrode was only 2 mA h g(-1). A high capacity of the graphene coating is due to defects of the graphene structure such as wrinkles, crumples, etc., and oxygen-functional groups attached to graphene during syntheses process. |
