Effect of different acid anions on highly efficient Ce-based catalysts for selective catalytic reductionof NO with NH3

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1399-1411 doi: 10.1007/s11705-023-2345-5

Abstract: Three kinds of Ce-based catalysts (CePO4, CeVO4, Ce2(SO4)3) were synthesized and used for the selective catalytic reduction (SCR) of NO by NH32(SO4)3, which is in agreement with their abilities of NH3 on NH3-SCR performances of Ce-based catalysts was systematically investigated by the X-rayThe key factors that can enhance the SCR are the existence of Ce4+, large NH3 adsorption
