제목 Effect of the oxygen vacancy concentration modified by preparation method on CeO2-promoted Mn/TiO2 catalysts for SCR reaction with NH3
초록 Selective catalytic reduction (SCR) reaction with NH3 had been commonly recognized as the most outstanding technology to abatement of NOx in flue gas from stationary sources. However, many engineers asked this method to operate at low temperature (below 250 oC) because of economic issue, and thus, many researchers tried to develop the catalyst having high efficiency at low temperature. Manganese is a promising element in response to these industrial requirement, and various types of Mn-based catalysts are currently developed and investigated. In this study, since the oxygen vacancy is a major factor to determine the catalytic efficiency for SCR reaction with NH3, we would like to clarify the relationship between catalytic performance and oxygen vacancy concentration on Mn-Ce/TiO2 catalyst by changing the impregnation sequence. This investigation would be helpful to better understand the influence of oxygen vacancy affecting on SCR reaction.
