Synthesis and comparative studies of MnFe2O4 nanoparticles with different natural polymers by sol–gel method: structural, morphological, optical, magnetic, catalytic and biological activities

Nanosized manganese ferrite (MnFe2O4) particles were prepared by sol–gel method using natural polymers like wheat flour (WF) and potato flour (PF) as surfactants and its structural, morphological, optical and magnetic characteristics were studied by X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), scanning electron microscope (SEM), photoluminescence spectroscopy (PL) and vibration sample magnetometer (VSM)....
