Catalytic degradation of 4-nitrophenol by activated carbon fiber supported iron tetrasulfophthalocyanine

合成了高活性的四磺酸基铁酞菁(FePcS),通过酰氯化反应将FePcS负载到乙二胺改性的活性碳纤维(ACF)上,制备新型催化活性碳纤维(ACF-FePcS),并通过紫外漫反射光谱和X射线光电子能谱对其结构进行表征.以H2O2为氧化剂,研究了ACF-FePcS对4-硝基苯酚(4-NP)的催化降解性能.结果表明,在室温25℃,反应4h后,4-NP的去除率达90%以上,且在较广的pH和温度范围内都有较高活性.因此,ACF-FePcS具有"富集-原位催化降解"的特点,在去除有机污染物方面具有较好的应用前景.
