摘要
以CTAB为模板采用共沉淀法合成CuO/CeO2复合物,用透射电镜、X射线粉末衍射和紫外可见光谱对复合物进行表征;研究CuO/CeO2复合物对茜素红的催化脱色效果.实验结果表明,CuO/CeO2复合物既具有吸附作用也具有光催化降解作用,且随着CuO含量和催化剂用量的增加催化脱色效果有明显提高.
In the presence of the CTAB soft template, the CuO/CeO2 nanocomposites were prepared by co-precipitation process. The product was characterized by TEM, XRD and UV-vis spectra. The experimental results showed that CuO/CeO2 nanocomposites had a strong adsorptive decolorization activity for organic dye alizarin red. Furthermore, its decolorization activity for alizarin red increased with the increase of the CuO content. Under illumination, this decolorization activity could be further enhanced due to the catalysis of the CuO/CeO2 nanocomposites.
