Abstract
In this study, the nano-sized ZnO/Bi2O3 composites were synthesized with the zinc-bismuth bimetallic-MOFs as the precursor for the first time. The metal ions were homogeneously anchored on the self-assembled precursor with a structure of hollow sphere. The results showed that the obtained ZnO presented a typical structure of hexagonal prismatic and an even distribution of element Zn and Bi was realized. Utilized as anode materials of Zn/Ni battery, the composites displays an ultra-high average discharge capacity of 630 mAh g−1 at 1 C and longer cycle life than the unmodified pure ZnO.
