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

Abstract: 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 NO 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 theco-feed (CO , O , H O or O /H O) on the N O decomposition was also investigated.
