Properties of La1-xCexCoO3 system perovskite-type catalysts for diesel engine exhaust removal

GONG Cairong, FAN Guoliang, HOU Yanfeng, ZHANG Zhongrong, SONG Chonglin, HUANG Qifei

Frontiers of Chemical Science and Engineering 2007, Volume 1, Issue 1,   Pages 6-10 doi: 10.1007/s11705-007-0002-z

Abstract: A series of complex oxide LaCeCoO catalysts was synthesized at a low temperature through a combustion process, in which x is among 0, 0.1, 0.2, 0.4 and 0.6 corresponding to the quantity of La partial substitution by Ce. The catalysts were characterized for phase composition using chemical analysis and X-ray diffraction. The catalytic activity of the catalysts in removal of NO, total hydrocarbon (THC) and particulate matter (PM) from diesel exhaust gases were examined in detail using temperature-programmed reaction technique. The results show that after partial substitution of La with Ce, the oxygen vacancy concentration increases significantly and a Co-Co system is formed. Consequently, the catalytic activity in the removal of THC and NO is significantly improved. But for the PM, the effect is not so obvious. The possible catalytic mechanism for this was presented. It is also worth noting that the doped catalysts showed good stability.

Mayenite supported perovskite monoliths for catalytic combustion of methyl methacrylate

Zekai ZHANG, Zhijian KONG, Huayan LIU, Yinfei CHEN

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 1,   Pages 87-94 doi: 10.1007/s11705-014-1410-5

Abstract: To improve their thermal stability, La Sr MnO cordierite monoliths are washcoated with mayenite, which is a novel Al-based material with the crystal structure of 12MO·7Al O (M= Ca, Sr). The monoliths are characterized by means of nitrogen adsorption/desorption, scanning electron microscopy, and X-ray diffraction. Catalytic performances of the monoliths are tested for methyl methacrylate combustion. The results show that mayenite obviously improves both the physic-chemical properties and the catalytic performance of the monoliths. Because mayenite improves the dispersity of La Sr MnO and also prevents the interaction between La Sr MnO and cordierite or -Al O , both crystal structure and surface morphology of La Sr MnO phase can thereby be stable on the mayenite surface even at high temperature up to 1050 oC. Under the given reaction conditions, La Sr MnO monolith washcoated with 12SrO·7Al O shows the best catalytic activity for methyl methacrylate combustion among all the tested monoliths.
