摘　　要：针对铁基非均相催化Fenton反应矿化降解废水中有机污染物存在强酸溶液中Fe2+/Fe3+的过量浸出、长期耐久性差等问题,综述了铁基金属有机骨架材料(Fe-MOFs)的溶剂热法等常用合成方法,概括了其在废水处理中染料吸附、有机污染物降解、分子检测中的应用,并重点介绍Fe-MOFs作为可见光催化剂增强Fenton与类Fenton反应的降解有机污染物的应用。相关研究表明,Fe-MOFs是一种新型多孔无机-有机材料,能一定程度拓宽pH应用范围,具有大量的铁位点,是一种优良的Fenton催化剂。但因存在合成能耗高、稳定性差与污染物降解不彻底等问题,探索低能耗、安全环保的合成方法,合成催化活性和稳定性均衡的Fe-MOFs以提高降解率使废水中有机污染物完全矿化是Fe-MOFs的发展趋势。To solve the problems of excessive leaching of iron ions from strong acid solutions and poor long-term durability of iron-based non-homogeneous catalytic Fenton reaction for mineralization degradation of organic pollutants in wastewater,the common synthesis methods such as a solvothermal method of Fe-based organic skeletal materials(Fe-MOFs)were reviewed.Their applications in dye adsorption,organic pollutants degradation,and molecular detection in the field of wastewater treatment were outlined.The emphasis on the application of Fe-MOFs as visible photocatalysts to enhance Fenton and Fenton-like reactions for degrading organic pollutants was highlighted.Relevant studies showed that Fe-MOFs as a new type of porous inorganic-organic material can broaden the application of pH range to a certain extent.The Fe-MOFs as the excellent Fenton catalyst have a large number of iron sites.However,there are still problems such as high energy consumption in the synthesis technology,poor stability,and incomplete degradation of pollutants.It is the development trend of Fe-MOFs to explore low energy consumption,safe and environmentally friendly synthesis methods,and synthesize Fe-MOFs with balanced catalytic activity and stability,improving the degradation rate so that organic pollutants can be completely mineralized in the wastewater.
