Superabsorbent Polymer as Nanoreactors for Preparation of Hematite Nanoparticles and Application of the Prepared Nanocatalyst for the Friedel-Crafts Acylation

The synthesis of pure alpha-Fe2O3 nanoparticles (30 nm) using a superabsorbent nanopolymer (SANP) by the thermal decomposition is reported. Synthesized alpha-Fe2O3 nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electronic microscopy (TEM) and thermogravimetric analysis (TG) techniques. The applicability of this nanostructure material was assessed by its catalytic effect on the Friedel-Crafts acylation.
