The nanocomposite of Mn0.25Fe2.75O4/CNC hybrid catalyst was synthesized using the co-precipitations method. Interestingly Cellulose Nanocrystal (CNC) has been prepared from medical cotton. The IR spectra of the Mn0.25Fe2.75O4/CNC nanocomposite showed that Fe-O and Mn-O vibrations were detected on wavenumber around 523 cm-1–710 cm-1 those vibrations confirm that Mn0.25Fe2.75O4 was successfully formed. Meanwhile, the success of CNC nanoparticles in Mn0.25Fe2.75O4/CNC hybrid catalyst was detected at 1000 cm-1 – 1650 cm-1. The XRD pattern showed that the samples were having two phases of crystal. The Fe3O4 phase in cubic spinel in nanometric size and the highest peak on the (311) plane. The amorphous peak of the CNC phase on 2θ was aro of 22.5º. Furthermore, characterizations of magnetic properties showed that the Mn0.25Fe2.75O4/CNC nanocomposite has superparamagnetic properties with S shape hysteresis loop. © 2025 American Institute of Physics Inc..
