Synthesis and spectroscopic characterization of Fe3+-BDC metal organic framework as material for lithium ion batteries

• The synthetized mixture of Fe-MOFs were characterized by XRD. spectroscopic properties the investigated IR. electrochemical CV, EIS and charge-discharge methods. cavities channels calculated used in order to predict possible accommodation sites for Li + ions. interactions described structures compounds. This work presents synthesis characterization a new metal-organic framework (MOF). compound Fe-BDC-DMF was solvothermal method prepared via reaction between FeCl 3 . 6H 2 O benzene-1,4-dicarboxylic acid (H BDC) or terephthalic using N,N-dimethylformamide (DMF) as solvent. powder X-ray diffraction (PXRD), scanning electron microscopy (SEM) infrared spectroscopy (IR) analysis. typical lithium-ion battery electrolyte cyclic voltammetry (CV), impedance (EIS) galvanostatic charging discharging. (MOF) contains three phases, identified PXRD as: MOF-235, MIL-53(Fe) monoclinic with C2/c P21/c space groups. structure Fe-BDC is built up from Fe 3+ ions, terephalates (BDC) bridges in-situ-generated DMF ligands. measurements conducted potential range 0.5–3.5 V vs. /Li 0 show voltage profiles plateau capacity around 175 mAh/g.
