Iron oxide is widely known as a catalyst, pigment and gas sensitive material. There are many developed methods for the synthesis of Iron oxide such as: sol-gel, electrochemical techniques, sputtering, vapor deposition and hydrothermal. Mentioned methods have proven to be advantageous in different aspects, but recently attentions has drawn to methods which are both eco-friendly and commercially feasible. Template synthesis using Xanthan gum and water as the solvent is a green approach. Xanthan gum (XG) is a water-soluble heteropolysaccharide including hydroxyl units along its backbone and branches can provide xanthan gum with capability of forming hydrogel networks. In this study, Fe(NO₃)₃.9H₂O is used as the Iron source, glycine and ammonium nitrate are co-oxidizers and Xanthan gum is the template. The synthesis of Iron oxide particles and the removal of template are undertaken by microwave radiation. Physical properties of products depend on the power and duration of microwave exposure. The prepared samples are characterized by Fourier-Transform Infrared spectroscopy (FT-IR), powder X-Ray Diffraction (XRD) and SEM.
