摘　　要：以碳纳米管(CNTs)为模板,硝酸锌和硝酸铁为原料,采用微波法合成了CNTs负载ZnFe2O4纳米粒子(1)的复合材料1/CNTs(2),其结构和形貌经XRD,SEM,TEM和EDS表征。以罗丹明B的光催化降解为探针反应,考察了2的光催化降解活性。结果表明:立方尖晶石结构的1均匀地负载在CNTs表面;在紫外光照射下,罗丹明B的光催化降解反应遵循一级反应动力学;2对罗丹明B的光催化降解活性明显高于1。Composite material [ 1/CNTs （2） ] of carbon nanotubes （CNTs） loaded ZnFe2 04 nanocom- posites（1） were synthesized by microwave-assisted using zinc nitrate and iron nitrate as the sources and CNTs as the template. The structure and morphology of 2 were charaterized by XRD, SEM, TEM and EDS. The photoactivities of 2 were investigated by photocatalytic degradation aqueous solutions of rhodamine B under ultraviolet-visible. The result showed that 1 with cube face-centered structure uniformly loaded on the surface of CNT, and the degradation of rhodamine B followed first-order reaction kinetics, and 2 showed higher photoactivity than 1.
