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.

Cu2O–PNIPAM core–shell nanoparticles have been synthesized to protect Cu2O nanocubes from oxidation and applied as active “nanoreactors” with tunable catalytic activity with temperature for the photocatalytic decomposition of methyl orange.
