非均相Fenton催化降解酚类化合物的研究进展

Research progress in the degradation of phenolic compounds by heterogeneous Fenton catalytic degradation

非均相Fenton催化法是去除水中难降解有机污染物的一种重要高级氧化技术,近些年以其效率高、污染少、材料来源广泛而受到人们更多的重视。介绍了现今主要的非均相Fenton催化降解酚类化合物的催化剂研究进展,包括零价铁、Fe3O4、Fe2O3、以碳、黏土、柱撑黏土、沸石、介孔二氧化硅等为载体的催化剂。最后提出了三个非均相Fenton反应的研究方向。

Heterogeneous Fenton catalysis is a kind of important and advanced oxidation technology for the removal of refractory organic pollutants from water, such as phenols in water. In recent years, more attention has been paid to heterogeneous Fenton reaction,in view of its characteristics, such as high efficiency,less pollution and wide material sources. The present research progress in some main heterogeneous Fenton catalysts,including zero-valent iron, Fe3O4 and Fe2O3, which are loaded on carbon, clay, pillared clays, zeolites, mesoporous silica, etc., for the degradation of phenol compounds, is introduced. At the end, three research directions of heterogeneous Fenton reactions are proposed.
