This work focuses on the preparation of a novel carbon fiber fabric containing a bimetallic metal-organic framework (B-MOF) based on iron (Fe) and nickel (Ni). The B-MOF was grown in the presence of the carbon fibers during a hydrothermal reaction (Figure 1a), resulting in a new material decorated with Fe-Ni(BDC) nanoparticles.

Initial characterizations of Fe-Ni(BDC)@CF were performed, with a focus on X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR). The XRD pattern (data not shown) indicated that Fe-Ni(BDC) had formed with the expected crystalline structure, as detailed in the literature. The FTIR spectrum confirmed the formation of Fe-Ni(BDC) on the carbon fiber surface. Scanning electron microscopy (SEM) coupled with energy dispersive X-ray spectroscopy (EDS) (Figure 1b) revealed the presence of Ni and Fe on the carbon fibers at concentrations of 0.05% and 0.12%, respectively...
