Research On Performance Of Iron-based Catalyst For Catalytic Removal Of NO/CO

NO is one of the major atmospheric pollutants,which will cause haze,acid rain and photochemical smog and a series of environmental problems.CO is a kind of poisonous gas which is harmful to human health,and it is also an excellent reducing agent.Catalytic reduction of NO by CO can simultaneously eliminate these two kinds of harmful gases,and it is of great significance.Because the iron-base catalyst has the advantages of excellent water resistance,low cost,non-toxic harmless.The catalyst has high development potential.The larger surface?-Al₂O₃ as the catalyst,the catalyst of two kinds of crystal surface iron as the effective component as the object,on the catalytic performance of NO reaction in the reduction in the removal of NO and CO reaction.Preparation of Fe₂O₃?104?/Al₂O₃ with low miller index by using co precipitation method to prepare high miller index crystal surface Fe₂O₃/Al₂O₃.The performance of NO under different reduction degree,different temperature and different proportion of NO/CO gas was studied.Two kinds of samples were characterized by TEM,SEM,XRD and XPS,and the differences of the internal structure and composition of the catalytic activity of the samples were found.
