摘要
采用非均相沉淀法合成纳米ZnO-CeO2复合材料。考察了原料配比,反应温度,pH值对产品紫外吸光性能的影响,从而确定最佳工艺。采用FTIR,XRD,UV-Vis对样品进行表征分析。结果表明:在最佳工艺条件下所制备的样品为氧化锌和氧化铈混合物相,复合纳米的平均粒径大约为15nm;该材料对245～400nm之间的紫外光有良好的吸收,且吸收边界延伸到400nm以后,可作为良好的紫外吸收材料。
The ZnO-CeO2 nano-composite particles were prepared by heterogeneous method.The effects of different ratios of reactants,reactive temperature and pH on its absorption capability in UV ray region were investigated.Optimal preparation conditions were obtained.The ZnO-CeO2 samples were characterized by FTIR,XRD and TEM.The results indicated that the prepared composite nanoparticles were ZnO and CeO2,and the average size of the ZnO-CeO2 sample was about 15nm;The UV absorption capability was investigated by UV-Vis.There was a broad peak between 245nm and 400nm in UV ray region.Its absorbing boundary extended to 400nm.The composite particle had a prosperous applied future as UV-absorbing material.
