多相芬顿催化的机理及技术研究

多相芬顿技术是一种有效的降解水中有机污染物的方法。相比经典芬顿反应，多相芬顿反应具有可循环利用、pH响应范围宽、不产生铁泥，以及易于固液分离等优点。但多相芬顿催化体系存在中性条件下活性低、催化剂稳定性差以及过氧化氢利用率低等瓶颈。为解决上述瓶颈，优异的多相芬顿催化剂通过多活性中心和多种技术共同耦合，增强催化活性。为进一步拓展芬顿技术的应用范围，芬顿反应研究需从几个方面展开：提高pH适用范围，提升催化剂的催化活性和稳定性，开发成本低廉、降解高效的多相芬顿催化剂。

Research on Mechanism and Technology of Heterogeneous Fenton Catalyst

Heterogeneous Fenton technology is an effective method to degrade organic pollutants in water. Compared with the classical Fenton reaction, the heterogeneous Fenton reaction had the advantages of recyclable, wide pH response range, no iron sludge, and easy solid-liquid separation. However, the heterogeneous Fenton catalytic system had the bottleneck of low activity under neutral conditions, poor catalyst stability and low hydrogen peroxide utilization rate. In order to solve the above bottlenecks, excellent heterogeneous Fenton catalysts were coupled with multiple active centers and co-synergism with multiple technologies to enhance catalytic activity. In order to further expand the application of Fenton technology, the study of Fenton reaction needs to be carried out from several aspects: improving the pH application range, enhancing the catalytic activity and stability, and developing heterogeneous Fenton catalysts with low cost and high degradation efficiency.
