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)> Ce2(SO4)3, which is in agreement with their abilities of NH343–, VO43– and SO42–SO2, and the upward trend about 8% was detected due to the sulfation enhancement by SO2 for Ce2(SO4)3.

Rh2O3/hexagonal CePO4 nanocatalysts for N2O decomposition

Huan Liu, Zhen Ma

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 4,   Pages 586-593 doi: 10.1007/s11705-017-1659-6

Abstract: Hexagonal CePO nanorods were prepared by a precipitation method and hexagonal CePO nanowires were prepared by hydrothermal synthesis at 150 °C. Rh(NO ) was then used as a precursor for the impregnation of Rh O onto these CePO materials. The Rh O supported on the CePO nanowires was much more active for the catalytic decomposition of N O than the Rh O supported on CePO nanorods. The stability of both catalysts as a function of time on stream was studied and the influence of the co-feed (CO , O , H O or O /H O) on the N O decomposition was also investigated. The samples were characterized by N adsorption-desorption, inductively coupled plasma optical emission spectroscopy, X-ray diffraction, transmission electron microscopy, X-ray photoelectron microscopy, hydrogen temperature-programmed reduction, oxygen temperature-programmed desorption, and CO temperature-programmed desorption in order to correlate the physicochemical and catalytic properties.
