Abstract
Abstract Strontium-doped iron chromites nanoparticles were synthesized using sol-gel method. Using co-precipitation method, two-dimensional MXene-based nanocomposite was synthesized for the first time. The characterization of nanocomposite Fe1-xSrxCr2O4/MXene was done using X-ray diffraction, scanning electron microscopy (SEM), energy-dispersive spectroscopy, Raman spectroscopy, photoluminescence spectrum (PL) and zeta potential. In nanocomposite Fe1-xSrxCr2O4/MXene, x=0.2, 0.4, 0.6, 0.8 strong intensity peaks observed as compared to MXene parent material. SEM results showed that spinel chromite Fe1-xSrxCr2O4 nanoparticles were attached on the surface of MXene. From 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 noticeable reduction in band gap values it has potential applications in optical devices.
