Abstract

Abstract.Experiments were conducted to evaluate the effect of adding ethanol amine during the preparation of a V/TiO2 catalyst to remove nitrogen oxide (NOx) by selective catalytic reduction (SCR). The catalyst added monoethanolamine (MEA) had the highest NOx conversion among all the neutralization reagents tested, and the optimum MEA concentration was determined to be 10%. The catalyst-added MEA had a large amount of lattice oxygen, which was determined in the O2 on/off experiment. In addition, it also displayed a high reoxidation rate in the O2 reoxidation experiment. In the XPS analysis, the superior redox properties of the catalyst-added MEA were shown to be caused by the presence of Ti^(+3), a non-stoichiometric species
