| 摘 要： | 以碳纳米管(CNTs)、纳米ZnO/Zn复合粉体和造孔剂聚甲基丙烯酸甲酯(PMMA)微球为原料,通过超声分散、真空抽滤、焙烧的方法制备ZnO/Zn/CNT三维多孔复合结构.利用扫描电子显微镜(SEM)、X射线衍射仪(XRD)、能谱仪(EDS)和拉曼光谱仪对样品的微观结构及成分进行表征.结果显示,样品内部存在大量的连通孔,ZnO/Zn复合粉体均匀分散于CNTs所构筑多孔结构的孔隙中.在多孔复合结构的制备过程中,ZnO晶体结构未发生变化也无杂质生成.多孔复合结构对模拟污染物甲基橙的暗室催化降解结果证明,由于独特的孔结构存在和ZnO与CNTs的协同作用,使得样品在80min时对甲基橙的降解率达99.9%.

| Abstract: | The carbon nanotubes (CNTs),ZnO/Zn nanopowder and pore-forming agent polymethyl methacrylate (PMMA) microparticles were treated by ultrasonic dispersion,filtration and calcinations to prepare ZnO/Zn/CNT porous composite structures.The as-prepared samples were characterized by scanning electron microscopy (SEM),X-ray diffraction(XRD),energy disperse spectroscopy(EDS) and Raman spectroscopy.The characterization results show that a large number of pore structures exist within the sample and the ZnO/Zn composite powder is embedded in the pores interwoven by CNTs.In addition,the crystal structure of ZnO nanorods does not change in the preparation of ZnO/Zn/CNT porous composite structure.The degradation experiments show that because of the existence of the pore structure and the synergy of ZnO with CNTs,the degradation rate of methyl orange is about 99.9% after 80 minitues reaction. |
