研究强化非均相电-Fenton深度降解难降解有机物的新方法，对工业废水回用具有深远意义。本项目通过制备具有“三明治”结构（碳材料/合金/非均相Fenton催化剂）复合材料，并修饰阴极电极，以多氯联苯作为模拟污染物，利用合金相分离所产生的应力强化电催化合成过氧化氢与非均相Fenton反应过程，实现有机物在阴极高效降解，最终研究出强化非均相电-Fenton电化学过程的新方法。项目拟重点研究合金相分离所产生应力强化过氧化氢和羟基自由基产生过程及其机制，构建催化剂结构（电子结构和原子结构）与效能关系，阐明有机物降解机制。通过本项目研究，不仅可提供一种强化非均相电-Fenton工艺的新方法，也为优化催化氧化工艺所采用催化剂的性能提供理论指导，最终为废水安全回用提供技术支撑。

Research on enhancement technology of heterogeneous electro-Fenton for degradation of refractory organics has far-reaching significance for industrial wastewater reuse. In this project, the sandwich-like nanomaterials (Carbon materials-Alloy-Heterogeneous Fenton catalysts) will be synthesized to decorate cathode. By using strain induced by alloy phase segregation, the processes of electro-catalytic synthesis of hydrogen peroxide and heterogeneous Fenton reaction are simultaneously enhanced. Taking polychlorinated biphenyls as model compounds, the organics will be effectively mineralized at the cathode. Herein, we will put emphasis on the effects of strain induced by alloy phase separation on catalyst performance during the hydrogen peroxide and hydroxyl radical generation process and the corresponding mechanism. Furthermore, Direct control of the electronic structure and atom arrangement of each layer in a sandwich-like nanostructure will provide a platform to gain better understanding of strain effects on catalytic activity. In addition, the degradation mechanism of polychlorinated biphenyls will be also clarified. According to the above study, the aim will not only supply a new channel to enhance heterogeneous electro-Fenton process, but present theoretical guidance for optimization of catalytic performance in the catalytic oxidation technology, and finally offer technical support for safe reuse of industrial wastewater.
