MOFs 及其衍生物在非均相 Fenton 催化中应用的研究进展

As an advanced oxidation process (AOP), heterogeneous Fenton oxidation can effectively solve the problems of traditional Fenton technology, such as narrow applicable pH range, easy to produce iron sludge, and difficult to recover catalyst, but its reaction activity is limited by the catalyst material. This paper introduces the application of MOFs and its derivatives in heterogeneous Fenton technology in recent years. The advantages of MOFs and their derivatives, such as large specific surface area, abundant active sites, and easy structural control, which could improve the bottlenecks of the heterogeneous Fenton technology, such as insufficient active sites, low Fe²⁺/Fe³⁺ cycle efficiency, and poor mass transfer efficiency, were analyzed. This work summarizes the research progress on modifying MOFs to obtain high activity catalysts, and points out the shortcomings of the current application of MOFs as catalyst materials. In the future, MOFs catalyst researches should focus on modification design for high activity and their commercial application.
