Mechanistic investigation of the enhanced NH 3 -SCR on cobalt-decorated Ce-Ti mixed oxide: In situ FTIR analysis for structure-activity correlation

Liu Jie , Li Xinyong , Zhao Qidong
ABSTRACT
Graphical abstractHighlights • Adjustment of the ratio of surface Ce 3+ and oxygen vacancies by Co decoration. • L-H and E-R mechanisms are accelerated by the aggravation of lattice distortion.Abstract A series of transition metals (Co, Cu and Fe) were selected to decorate Ce-Ti mixed oxide to elevate the low-temperature activity of selective catalytic reduction of NO x by NH 3 (NH 3 -SCR) reaction, by adjusting the ratio of surface Ce...
