Abstract:

As a solution to overcome the shortcomings of homogeneous Fenton reaction, heterogeneous Fenton catalytic oxidation technology has been intensively investigated in the field of water treatment due to the advantages of high removal efficiency under wide range of pH and easy separation and reutilization. This article firstly introduces the development of heterogeneous Fenton catalytic oxidation technology for the degradation of organic pollutants, the mechanisms of heterogeneous Fenton reaction as well as the characterization and experimental methods to study the mechanisms. The categories of heterogeneous Fenton catalysts are reviewed, including iron oxides, other metal oxides, and metal organic framework materials. Particularly, the methods to improve the catalytic activity and stability of heterogeneous Fenton catalysts are discussed, which include regulating the morphology, size and pore structure of the catalyst to improve the specific surface area, loading the catalysts onto carriers with high specific surface area, compositing the catalysts with other transition metal and introducing the outfield(such as light, ultrasonic and microwave). Finally, the future development of heterogeneous Fenton catalysts is pointed out.
