Abstract

Graphene–ZnO nanocomposite was successfully synthesized via microwave-assisted reduction of zinc ions in aqueous solution with graphite oxide dispersion using a microwave synthesis system. The electrochemical performance of the nanocomposite was analyzed through cyclic voltammetry and chronopotentiometry tests. The results showed that as compared with pure graphene, graphene–ZnO composite exhibited an improved electrochemical capacitance of 146 F/g with good reversible charge/discharge behavior.
