In this work, a fabrication route for generating organic–inorganic polymer hybrid materials was discussed. Natural cellulose was extracted form Sesbania sesban to design a biodegradable microcomposite. A novel iron schiff base was immobilized on this extracted biopolymer via amin functionality (FeSAC). The structure, morphology and thermal stability of FeSAC were characterized by scanning electron microscopy (SEM), Energy-dispersive X-ray spectroscopy (EDAX), FT-IR, ‎Inductively coupled plasma (ICP), Thermo gravimetric analysis (TGA) and elemental analysis. The synthesized catalyst was successfully applied as a green heterogeneous catalyst in the oxidation reaction under a solvent free media and hydrogen peroxide providing as a green promising system for industrials application. High yield products and selectivities were observed. The longevity of the microcatalyst was studied and it was found to be reusable for at least six runs. Finally, α-Fe2O3 was obtained by direct calcinations of this biocatalyst at 650°C within 3h. α-Fe2O3 was characterized by SEM, high-resolution transmission electron microscopy (HR-TEM), and X-ray Powder Diffraction (XRD).
