摘　　要：通过水热法,以Zn(CH_3COO)_2·2H_2O和(NH_4)_2Fe(SO_4)_2·6H_2O为反应物,成功制备了叶状ZnFe_2O_4/ZnO Fenton复合光催化材料,分析了所制备的样品的其形貌、结构和光学性质。加入H2O2后通过在可见光(波长≥420 nm)下降解了邻苯二甲酸二丁酯(DBP)研究了样品的光催化性能。结果表明,ZnFe_2O_4/ZnO在210 min内能将降解92%的DBP,具有比纯相ZnFe_2O_4(降解70%的DBP)更高的活性,其活性更高的原因是ZnFe_2O_4和ZnO之间形成的异质结与ZnFe_2O_4和H_2O_2形成的类Fenton催化剂的协同作用的结果。Leaf-like ZnFe2O4/ZnO Fenton-like composite photocatalyst was prepared successfully via a hydrothermal method using Zn(CH3OO)2·2 H2O and(NH4)2Fe(SO4)2·6 H2O as reactants. The crystal structure, morphology, and optical property of the as-prepareed samples were characterized. The photocatalytic activities of the samples were evaluated by decomposing di-butyl phthalate(DBP) in the presence of H2O2 under the visible light irradiation(λ≥420 nm). The results showed that, 92% of DBP could be degraded by ZnFe2O4/ZnO within 210 min, the photocatalytic activity of ZnFe2O4/ZnO was higher than that of pure ZnFe2O4(only 70% of DBP could be degraded). The enhanced photocatalytic activity could be attributed to the synergetic effects of heterojunction formed between ZnFe2O4 and ZnO and Fenton-like catalyst formed between ZnFe2O4 and H2O2.
