Abstract EN
Fe3O4 nanoparticle was synthesized in the solution involving water and ethanol.
Then, α-Fe2O3 shell was produced in situ on the surface of the Fe3O4 nanoparticle by surface oxidation in molten salts, forming α-Fe2O3/Fe3O4 core-shell nanostructure.
It was showed that the magnetic properties transformed from ferromagnetism to superparamagnetism after the primary Fe3O4 nanoparticles were oxidized.
Furthermore, the obtained α-Fe2O3/Fe3O4 core-shell nanoparticles were used to photocatalyse solution of methyl orange, and the results revealed that α-Fe2O3/Fe3O4 nanoparticles were more efficient than the self-prepared α-Fe2O3 nanoparticles.
At the same time, the photocatalyzer was recyclable by applying an appropriate magnetic field.
