中文摘要：

以偕胺肟纤维（AOCF）为载体,采用配位-沉淀法研制了一种新型的类Fenton催化剂CuO/AOCF.用SEM、EDS和XRD对CuO/AOCF的表面形貌、晶体结构和表面成分进行分析,结果显示：CuO纳米颗粒均匀分布在AOCF表面.以活性红染料为目标降解物及其去除率为评价指标,考察CuO/AOCF与H2O2组成类Fenton催化剂的光催化性能.结果表明：在氙灯光照作用下,0.6 g·L^-1CuO/AOCF、2 m L·L^-1H2O2、反应时间为80 min,活性红溶液几乎完全被降解.对比同质量粉体CuO,CuO/AOCF对光催化性能有着更好的促进作用.CuO/AOCF重复使用5次后降解率仍能大于80%.动力学研究表明,该类Fenton催化降解反应遵循一级反应动力学规律.

英文摘要：

A novel Fenton-like catalyst CuO/AOCF was prepared by ligand-precipitation method with AOCF as carrier. The surface morphology,crystal structure and surface composition of CuO/AOCF were characterized by SEM,EDS and XRD. The results show that the CuO nanoparticles evenly distributed on the surface of AOCF. The Fenton-like photocatalytic activity of CuO/AOCF and H2O2 was investigated. With the reactive red dye as model degradation compound,and its degrading rate was evaluated. The results showed that the reactive red dye solution can be almost completely degraded by0.6 g·L^-1CuO/AOCF and 2 m L·L^-1H2O2 under the Xenon lamp light irradiation for 80 min. Compared with the CuO powder,the CuO/AOCF has an excellent photocatalytic activity. The degradation rate of the reactive red dye could reach to 80% with repeated use of CuO/AOCF for 5 times. Results of kinetics studies show that this kind of Fenton-like catalytic degradation reaction fits first-order kinetic model.
