摘要:
Reduced graphene oxide/Fe2O3 composite was prepared using a facile two-step synthesis by homogeneous precipitation and subsequent reduction of the G-O with hydrazine under microwave irradiation to yield reduced graphene oxide (RG-O) platelets decorated with Fe2O3 nanoparticles. As an anode material for Li-ion batteries, the RG-O/Fe 2O3 composite exhibited discharge and charge capacities of 1693 and 1227 mAh/g, respectively, normalized to the mass of Fe 2O3 in the composite (and ∼1355 and 982 mAh/g, respectively, based on the total mass of the ...
