The strontium-doped iron chromite nanoparticles were synthesized using the sol-gel method. Using the co-precipitation method, two-dimensional MXene-based nanocomposite is synthesized. This is the first synthesis of MXene with doped spinel chromites. The characterization of nanocomposite Fe1−xSrxCr2O4/MXene is done using XRD, SEM, EDS, Raman spectroscopy, photoluminescence spectrum (PL), and zeta potential. In nanocomposites, Fe1−xSrxCr2O4/MXene, x = 0.2, 0.4, 0.6, 0.8 strong intensity peaks were observed as compared to MXene parent material. From SEM results it was depicted that spinel chromite Fe1−xSrxCr2O4 nanoparticles were attached to the surface of MXene. From the PL spectrum, the band gap values for MXene are 3.33 eV and decreased to 2.06 eV for nanocomposites Fe1−xSrx Cr2O4/MXene. The zeta potential has been achieved with negative values. The obtained results made this nanocomposite unique and beneficial for electrochemical applications and due to a noticeable reduction in band gap values it has potential applications in optical devices.
