摘　　要：采用溶胶-凝胶法制备了铁氧体CoFe2-xNixO（4x=0.1~0.5）系列样品。利用XRD,SEM对纳米颗粒的结构、形貌进行了表征。结果表明,所合成的样品为尖晶石型,呈圆球状,粒径均匀,直径约为50nm。通过甲基橙的降解情况对其脱色率进行了研究。结果表明,经过B位Ni2＋掺杂的CoFe2-xNixO（4x=0.1~0.5）系列样品,其脱色率明显提高。Ferrite with spinel structure CoFe2-xNixO4（x=0.1~0.5） were synthesized by sol-gel method.The size,structure and appearance of the synthesized nanoparticles were characterized by XRD and SEM.The results of the as-prepared CoFe2-xNixO4（x=0.1～0.5） paticles with sphericity are spinel structure and dispersive with the average size about 50nm in diameter.The decolor rate of CoFe2-xNixO4（x=0.1～0.5） samples was measured by the degradation of methylic orange,the results show that the B-site Ni-doping can distinctness heighten the decolor rate of CoFe2-xNixO4.
