Publication date: Available online 26 April 2019Source: Inorganica Chimica ActaAuthor(s): Bo-Wen Hu, Ya-Jie Zhu, Lei Du, Tian-Sheng Mu, Wen-Qi Zhu, Ge-Ping Yin, Peng Chen, Quan-Wen LiAbstractTwo novel isomorphous 2D NiII/CoII-NiII Metal-Organic Frameworks (MOFs) with tetrazole-1-acetate ligands have been synthesized and structurally characterized. And then they were calcined in air to obtain Ni/Co3O4-doped NiO electrodes. Compared to the homometallic MOF-derived oxide, the heterometallic MOF-derived bimetal oxides presented higher coulombic efficiency, better cycle performance, larger specific capacity as lithium-ion batteries anodes.Graphical abstractTwo new isomorphous 2D MOFs connected by tetrazole-1-acetate ligands have been designed and synthesized with full structural characterization. A novel heterometallic MOFs approach is presented to modulate electrochemical performances of MOF-derived transition metal oxides as anodes for Li-ion batteries (LIBs).
