Abstract
A nanocomposite of Mn 3O 4 wrapped in graphene sheets (GSs) was successfully synthesized via a facile, effective, energy-saving, and scalable microwave hydrothermal technique. The morphology and microstructures of the fabricated GS-Mn 3O 4 nanocomposite were characterized using various techniques. The results indicate that the particle size of the Mn 3O 4 particles in the nanocomposite markedly decreased to nearly 20 nm, significantly smaller than that for the bare Mn 3O 4. Electrochemical measurements demonstrated a high specific capacity of more than 900 mA h g -1 at 40 mA g -1, and excellent cycling stability with no capacity decay can be observed up to 50 cycles. All of these properties are also interpreted by experimental studies and theoretical calculations. © 2012 The Royal Society of Chemistry.
