英文摘要	A strategy for the formation of magnetic NixFe3-xO4 hollow nanospheres with very high specific surface areas was designed through a facile solvothermal method in mixed solvents of ethylene glycol and water in this work. The Ni/Fe ratios and the crystal phases of the NixFe(3-x)O(4) hollow nanocrystals can be readily tuned by changing the molar ratios of Ni to Fe in the precursors. An inside-out Ostwald ripening mechanism was proposed for the formation of uniform NixFe(3-x)O(4) hollow nanospheres. Moreover, the obtained NixFe(3-x)O(4) hollow nanospheres exhibited excellent adsorption capacity towards organic molecules such as Congo red in water. The maximum adsorption capacities of NixFe(3-x)O(4) hollow nanospheres for Congo red increase dramatically from 263 to 500 mg g(-1) with the increase of the Ni contents (x) in NixFe(3-x)O(4) hollow nanospheres from 0.2 to 0.85. The synthesized NixFe(3-x)O(4) nanoparticles can be potentially applied for waste water treatment.
