Characterization and photodegradation activity of hollow Zn^sub 1-x^Ni^sub x^Fe^sub 2^O^sub 4^ sphere

Carbon microspheres with good dispersibility were synthesized by hydrothermal method using glucose as raw material. Taking the as-prepared carbon microsphere as the template, a series of hollow Zn^sub 1-x^Ni^sub x^Fe^sub 2^O^sub 4^ spheres (x = 0-1 with interval of 0.2) were prepared by chemical precipitation method. The composition, morphology, electrical and magnetic properties of the hollow Zn^sub 1-x^Ni^sub x^Fe^sub 2^O^sub 4^ spheres were characterized. The results of nitrogen adsorption-desorption isotherms indicates that the Zn^sub 1-x^Ni^sub x^Fe^sub 2^O^sub 4^ catalyst with different Ni content presents different specific surface area. And the adsorption-photodegradation of samples on rhodamine B and methyl orange solutions were discussed. In addition, the influence of Ni content on material photocatalytic activity has been discussed. These results indicated that the recyclable ZnFe^sub 2^O^sub 4^ had a better decontaminating activity than other Zn^sub 1-x^Ni^sub x^Fe^sub 2^O^sub 4^ spheres.
