Controlled synthesis of α- and γ-Fe2O3 nanoparticles via thermolysis of PVA gels and studies on α-Fe2O3 catalyzed styrene epoxidation
Fe2O3 nanoparticles with diameters in the 7–18 nm range have been synthesized via thermolysis of polyvinyl alcohol (PVA) gels prepared under alkaline pH by adding Fe3+ ions into warm aqueous solutions of PVA. While calcinations at 400 °C, 500 °C and 600 °C give γ-Fe2O3 as the pure product, α-Fe2O3 i...
