▎ 摘　　要

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 (similar to 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. (C) 2015 Elsevier B.V. All rights reserved.
