Abstract
MnFe2O4/reduced graphene oxide nanocomposite (MnFe2O4/rGO) was synthesized by a facile and green strategy, which involves in situ reduction of GO in presence of Fe2+ as well as co-precipitation of Fe3+ and Mn2+ onto the surface of rGO. The composite consists of MnFe2O4 with its primary particles (~10 nm) decorated by rGO sheets, which could prevent the aggregation of the particles and ensure a relatively large specific surface area. It exhibits a specific capacity of 813.4 mA h g−1 at the current density of 0.2 A g−1 and a capacity retention of 80.3% after 100 cycles. Moreover, the proposed synthesis strategy can also be easily extended to prepare other MxFe1−xO4/rGO (M=Ni, Co, Zn, and Mg) composite materials.
