Abstract

Metal-organic frameworks (MOFs) with high surface areas and uniform microporous structures have shown potential application in many fields. Here we report a facial strategy to synthesize Fe₂O₃@NiCo ₂O₄ porous nanocages by annealing core-shell Co ₃[Fe(CN)₆]₂@Ni₃[Co(CN) ₆]₂ nanocubes in air. The obtained samples have been systematically characterized by XRD, SEM, TEM and N₂ adsorption-desorption analysis. The results show that the Fe₂O ₃@NiCo₂O₄ porous nanocages have an average diameter of 213 nm and a shell thickness of about 30 nm. As anode materials for Li-ion batteries, the Fe₂O₃@NiCo₂O₄ porous nanocages exhibit a high initial discharge capacity of 1311.4 mA h g ^-1 at a current density of 100 mA g^-1 (about 0.1 C). The capacity is retained at 1079.6 mA h g^-1 after 100 cycles. The synergistic effect of the different components and the porous hollow structure contributes to the outstanding performance of the composite electrode. This journal is
