Synthesis of Mn3O4-encapsulated graphene sheet nanocomposites via a facile, fast microwave hydrothermal method and their supercapacitive behaviour (original) (raw)

Well-crystallized Mn 3 O 4 -anchored reduced graphene oxide (rGO) nanocomposites have been successfully synthesized via a facile, effective, energy-saving, and scalable microwave hydrothermal technique for potential application as supercapacitor material. Integrating these nanostructures resulted in a strong synergistic effect between the two materials, consequently leading to a hybrid composite with higher specific capacitance compared to the bare Mn 3 O 4 nanoparticles. The results from different sorts of characterization indicate that the Mn 3 O 4 ∗ Corresponding author: Institute for Superconducting and Electronics Materials, University of Wollongong, Squires Way, Fairy Meadow, Wollongong 2519, NSW, Australia.Tel.:+61 2 4221 5225, Fax: +61 2 4221 5731, E-mail address: zguo@uow.edu.au .
