摘要
采用均匀沉淀法制备了镍锌铁氧体、纳米TiO2-ZnO复合粉体和镍锌铁氧体负载纳米TiO2-ZnO复合粉体,并用XRD对所制粉体进行了表征。发现所制得的纳米TiO2为锐钛矿型、镍锌铁氧体为尖晶石型。以甲基橙溶液为模拟废水,考察了纳米TiO2-ZnO复合粉体和镍锌铁氧体负载纳米TiO2-ZnO复合粉体的光催化活性。研究还发现镍锌铁氧体负载纳米TiO2-ZnO粉体后仍具有良好的磁性能,可通过增加外磁场进行分离。
TiO2-ZnO composite powders and TiO2-ZnO loaded with Ni0.5Zn0.5Fe2O4composite powders were prepared by homogeneous precipitation method.The powders obtained have been characterized by XRD.The results show that TiO2 is anatase-type and Ni0.5Zn0.5Fe2O4is Spinel-type.TiO2-ZnO composite powders and TiO2-ZnO loaded with Ni0.5Zn0.5Fe2O4composite powders have been employed in photocatalytic degradation of methyl-orange.The results show that TiO2-ZnO loaded with Ni0.5Zn0.5Fe2O4composite powders have good magnetic property,and can be separated by the external magnetic field.
