Synthesis and research of CeO2-V2O5/ATP for selective catalytic reduction of NOx in flue gas at low temperature

摘要：

　　The catalyst ofATP droped with CeO2 and V2O5 for NOx reduction by ammonia were prepared through sol-gel method,using several cheap ecofriendly materials(such as Ce(NO3)3 · 6H2O,NH4VO3 and attapulgite(ATP) clay which contains much magnesium aluminum silicate and abundant in nature).The catalysts are characterized by different techniques,FT-IR indicated that the ATP clay has been successfully modified by the functional CeVOx species; X-ray diffraction analysis verify that the natural ATP still existed in catalysts and the exist form of Ce and V; The activity of catalysts for selective catalytic reduction of NO in flue gas was tested and the CeO2-V2O5/ATP calcined at 400℃ displayed the highest efficiency value of nearly 95% at 220℃.The result shows that the catalyst is qualified with the ability of controlling and removing NO in flue gases at low temperature.
