Sorption is thought to be a versatile and effective approach for the removal of water pollutants and has been widely used in water purification. In this work, we have synthesized flowerlike gamma-Fe2O3@NiO core-shell hierarchical nanostructures though a facile method. The NiO shell can be easily controlled by altering the concentration of the nickel source. The obtained flowerlike gamma-Fe2O3@NiO core-shell hierarchical nanostructures exhibit superb adsorption capability as adsorbents for the removal of toxic pollutants from waste water. Importantly, the flowerlike gamma-Fe2O3@NiO core-shell hierarchical nanostructures still retained this adsorption activity even after being recycled three times with the help of an external magnetic field. Furthermore, the magnetic flowerlike gamma-Fe2O3@NiO core-shell hierarchical nanostructures may have potential practical use in catalysis, lithium-ion batteries, supercapacitors and so on.
