摘　　要：采用浸渍法制备Fe-Mn/TiO_(2)双金属催化材料,以双酚A(BPA)为目标降解物,探究了Fe-Mn/TiO_(2)对其的降解效果及降解机制。结果表明,Fe-Mn/TiO_(2)催化臭氧氧化降解BPA的去除率相较于单独TiO_(2)处理提升了83.4%;Fe、Mn成功负载且催化剂孔洞较丰富;相较于TiO_(2),Fe-Mn/TiO_(2)中锐钛矿质量分数增加能产生更多的羟基自由基。同时,Fe、Mn在TiO_(2)表面能发生价态转化,可作为活性位点促进臭氧分解为·OH等活性物质,增强催化反应活性。Fe-Mn/TiO_(2)bimetallic catalytic material is prepared via the impregnation method,and the degradation effect and mechanism of Fe-Mn/TiO_(2)are explored by degrading bisphenol A.The results show that the removal rate of BPA degradation through ozone oxidation over Fe-Mn/TiO_(2)is 83.4%higher than that over TiO_(2)treatment alone.Fe and Mn are successfully loaded,and the catalyst is rich in pore.The increase of anatase mass fraction in Fe-Mn/TiO_(2)can generate more hydroxyl radicals than that in TiO_(2).Meanwhile,both Fe and Mn can undergo valence transformation on the surface of TiO_(2),which can be used as active sites to promote ozone to decompose into·OH and other active substances,and enhance the catalytic reaction activity.
