金属有机骨架是制备多孔结构的方便前驱体。在微波照射下，将普鲁士蓝（一种mof）与醋酸锌反应，在普鲁士蓝表面形成氢氧化物和碳酸盐纳米片。通过热解得到ZnO/ZnFe2O4复合多孔纳米颗粒，并将其作为锂离子电池的负极材料。该复合材料在电流密度为1000毫安g（-1）时具有804毫安g（-1）的良好容量，可循环500次。(C) 2016 Elsevier B.V.版权所有
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.
