Metal organic frameworks (MOFs) are convenient precursors for preparing porous structures. In this work, the Prussian Blue (one kind of MOFs) is reacted with Zn acetate under microwave irradiation, forming hydroxides and carbonates nanosheets on the surface of Prussian Blue. After pyrolysis, a composite of ZnO/ZnFe2O4 porous nanoparticles was obtained and applied as anode material for lithium ion batteries. The composite shows a good capacity of 804 mAh g(-1) for 500 cycles at a current density of 1000 mA g(-1). (C) 2016 Elsevier B.V. All rights reserved.
