Abstract:
？将珍珠贝壳废弃物活化并作为载体,应用原位水解法制备出Cu2O/珍珠贝壳复合材料.运用X射线衍射、X射线光电子能谱、扫描电镜、紫外-可见漫反射吸收光谱对复合材料进行表征.用活性大红染料B-3G水溶液作为模拟废水评价复合材料在可见光下的催化性能.结果表明,负载的Cu2O呈椭球形,理论平均粒径为16.8nm.复合材料对紫外和可见光谱均有吸收.相对纯Cu2O而言,纳米Cu2O/珍珠贝壳复合材料在催化有机染料降解脱色实验中具有更高的活性,在适宜的环境条件下(pH为6.0~12.0,反应时间为90min,B-3G初始浓度≤220mg/L),催化B-3G降解脱色率达98%,催化反应过程符合伪一级反应动力学模型.此外,傅里叶变换红外光谱研究表明,纳米Cu2O/珍珠贝壳复合材料的形成源于Cu2O和CaO间的结合并发生相互作用.
