Fe3O4nanoparticle was synthesized in the solution involving water and ethanol. Then,α-Fe2O3shell was produced in situ on the surface of theFe3O4nanoparticle by surface oxidation in molten salts, formingα-Fe2O3/Fe3O4core-shell nanostructure. It was showed that the magnetic properties transformed from ferromagnetism to superparamagnetism after the primaryFe3O4nanoparticles were oxidized. Furthermore, the obtainedα-Fe2O3/Fe3O4core-shell nanoparticles were used to photocatalyse solution of methyl orange, and the results revealed thatα-Fe2O3/Fe3O4nanoparticles were more efficient than the self-preparedα-Fe2O3nanoparticles. At the same time, the photocatalyzer was recyclable by applying an appropriate magnetic field.
