为开发一种简单经济的湿法脱硝新工艺，采用浸渍法制备沸石载体负载Fe₂O₃的非均相类Fenton催化剂，并对其进行表征，同时考察了H₂O₂浓度、初始pH、催化剂质量浓度和反应温度对Fe₂O₃/沸石催化剂非均相类Fenton湿法脱硝效率的影响。结果表明，Fe₂O₃/沸石催化剂具有较大的比表面积，载体结构没有改变，活性组分Fe₂O₃均匀分散在载体上；Fe₂O₃/沸石催化剂具有明显的催化活性；H₂O₂浓度、初始pH、催化剂质量浓度和反应温度在最佳条件下，NO的脱除效率达52%；催化剂具有较好的稳定性，循环使用5次依然有48%左右的NO脱除效率。

In order to develop a simple and economical wet denitrification process,zeolite supported Fe₂O₃,a heterogeneous Fenton-like catalyst,is prepared through impregnation method and is then characterized.Meanwhile,the effects of H₂O₂ concentration,initial pH,catalyst dosage and reaction temperature on the efficiency of Fe₂O₃/zeolite catalyst in wet denitrification by heterogeneous Fenton-like method are investigated.The results show that the catalyst has a larger specific surface area,the structure of the carrier remains unchanged,and the active component Fe₂O₃ disperses evenly on the supporter.The of Fe₂O₃/zeolite catalyst has obvious catalytic activity.The removal efficiency of NO will reach 52% if H₂O₂ concentration,initial pH,catalyst dosage and reaction temperature all are set at theie own optimal values.NO removal efficiency is still around 48% after the catalyst has been used for 5 times,representing a good stability.
