Abstract:

Catalytic ozonation has been widely used in water treatment processes due to its advantages of environmental friendliness and high mineralization efficiency. Catalysts are one of the key factors determining the process stability and efficiency. Among numerous catalysts, heterogeneous iron-based catalysts have attracted widespread attention due to their extensive sources, low cost, excellent catalytic performance, and low toxicity. A comprehensive investigation of their preparation process, types, catalytic effects, and reaction mechanisms will be of great significance for further improving wastewater treatment efficiency and promoting technological development. This article first introduced the commonly used preparation methods of iron-based catalysts, including precipitation method, hydrothermal synthesis method, and impregnation calcination method, and discussed the catalytic effects of different types of iron-based catalysts on organic pollutants. In addition, the influence of main parameters such as active sites, reactant concentration, and mass transfer efficiency on the catalytic ozonation degradation of organic pollutants by iron-based catalysts was elucidated. And the catalytic mechanism of iron-based catalysts was explored from the aspects of ozone oxidation, reactive oxygen species, and catalytic components. Finally, the stability of iron-based catalysts was analyzed from the perspectives of deactivation causes and regeneration methods. Finally, future research directions were proposed, such as the analysis of the intrinsic relationship between water pollutant composition and preparation method of iron-based catalyst, environmental impact analysis, and quantitative analysis of reaction mechanisms.
