| 摘 要： | 采用温和的无模板溶液反应合成了α-Fe2O3/AC复合催化剂,作为光Fenton降解双酚A反应的催化剂。通过XRD、SEM、FTIR、DRS、BET、XPS等方法对催化剂的形貌和理化特性进行了分析。结果表明：该催化剂晶型良好,为介孔材料,能够有效吸收和利用紫外光和可见光;该催化剂具有较高的催化活性,稳定性良好;在初始双酚A质量浓度为30 mg/L、溶液pH为4、H2O2加入量为320 mg/L、反应温度为40 ℃、催化剂加入量为1.33 g/L的条件下,双酚A降解率可达91.4%。

| Abstract: | The α-Fe2O3/AC composite catalyst was synthesized by a mild solution reaction without template and used as catalyst for degradation of bisphenol A （BPA）by photo-Fenton reaction. The morphology and physicochemical properties of the catalyst were analyzed by XRD,SEM,FTIR,DRS,BET and XPS. The results showed that：The catalyst was a mesoporous material with good crystal form,and it could absorb and utilize ultraviolet and visible light effectively;It had high catalytic activity and stable performance;Under the conditions of initial BPA mass concentration 30 mg/L,solution pH 4,H2O2 amount 320 mg/L,reaction temperature 40 ℃ and catalyst amount 1.33 g/L,the degradation rate of BPA was 91.4%. |
