摘要
A bimetallic metal–organic framework (MOF) nanofiber TCPP(Fe)-Ni has been synthesized by a simple solvothermal method, and the ligand TCPP(Fe) has been synthesized by organic synthesis. The presence of metalloporphyrins ligands is beneficial for the transport of Li+ and electrons, which is conducive to enhancing lithium storage of the TCPP(Fe)-Ni anode. In addition, the chelating effect between the metal center Fe3+ and porphyrin will facilitate the cycle stability compared with Ni-TCPP MOF. The TCPP(Fe)-Ni material shows superior rate capability and high reversible capacity of 950 mAh g–1 at 0.1 A g–1 as an anode for lithium ion batteries (LIBs). This work provides an improved synthetic route of metalloporphyrins and a better understanding of porphyrin MOF as a high performance anode.
