摘要

Because the site for NH3 adsorption and the active site for NH3 oxidization were separated after the sulfation, both the SCR reaction and the catalytic oxidization of NH3 to NO over gamma-Fe2O3 were restrained after the sulfation. As a result, the operation temperature window of gamma-Fe2O3 for the SCR reaction shifted about 100 degrees C to higher temperature after the sulfation.
