| 摘 要： | 用微波法制备了碳纳米管负载ZnCdS纳米复合材料(ZnCdS/CNTs).通过扫描电子显微镜(SEM),透射电镜(TEM)和X-射线粉末衍射(XRD)测试表明:平均粒径为25 nm六方纤锌矿结构的ZnCdS纳米粒子均匀分散在碳纳米管表面.ZnCdS/CNTs纳米复合材料在可见光下光催化降解甲基橙和罗丹明溶液.结果表明:催化剂用量为0.02g/L条件下,对初始浓度均为100mg/L的甲基橙和罗丹明溶液进行可见光光照50min后,降解率分别达到97%和96.7%;催化剂重复使用3次后,光照50min后甲基橙和罗丹明的降解率仍可达到92%和91%.

| Abstract: | The ZnCdS nanoparticles supported on carbon nanotubes(ZnCdS/CNTs) have been prepared by microwave-assisted route.The nanocomposites have been characterized by scanning electron microscopy(SEM),transmission electron microscopy (TEM),and X-ray diffraction(XRD),which show that ZnCdS nanoparticles with average diameters about 25nm and hexagonal wurtzite phase dispersed on the surface of the carbon nanotubes.The photocatalytic degradation of methyl orange(MO) and Rhodamine B(RhB) was investigated under visible l... |
