利用水热法制备了新型金属有机骨架MOF（Fe）作为光-芬顿催化剂，通过XRD、TEM、FITR和BET对催化剂进行表征。利用光-芬顿体系下对酸性大红3R（AR3R）的催化降解效果来评价MOF（Fe）的催化活性，考察了AR3R初始质量浓度、pH、MOF（Fe）的质量以及H₂O₂的用量对AR3R催化降解性能的影响。结果表明，在可见光下，AR3R初始质量浓度为200 mg/L、pH为3.0、H₂O₂的用量为0.4 mL、MOF（Fe）的质量为0.20 g时，经过45 min反应后AR3R降解率为100%。通过捕获剂实验确定·OH、·O₂和h⁺在反应体系中均起着重要作用。重复利用实验表明，MOF（Fe）具有较高的稳定性。

A new metal-organic framework MOF(Fe),as a photo-Fenton catalyst,is prepared by hydrothermal method,and is characterized by X-ray diffraction (XRD),transmission electron microscopy (TEM),infrared spectroscopy (FITR) and specific surface area (BET).The catalytic activity of prepared MOF(Fe) is evaluated through catalytic degradation of acidic red 3R (AR3R) under photo-Fenton system.The effects of catalyst dosage,H₂O₂ amount and water quality conditions (initial concentration of AR3R and pH) are investigated for AR3R degradation.The results show that under visible light,the degradation rate of AR3R has reached 100% after 45 min of reaction when the initial concentration of AR3R is 200 mg·L^-1,the pH value is 3.0,the dosage amount of H₂O₂ is 0.4 mL,and the dosage of MOF(Fe) is 0.20 g.Further scavenging experimental results reveal that the hole,·O₂ and the ·OH all play a crucial role in the reaction process.The reuse experiments verify that MOF(Fe) has a high stability.
