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.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.

Complete oxidation of methane on CoO-SnO catalysts

Xingfu TANG , Jiming HAO , Junhua LI ,

Frontiers of Environmental Science & Engineering 2009, Volume 3, Issue 3, Pages 265-270 doi: 10.1007/s11783-009-0019-2

Abstract: CoO-SnO hybrid oxides were prepared by the coprecipitation method and were used to oxidate methane (CH) in presence of oxygen. The CoO-SnO with a molar ratio of Co/(Co+Sn) at 0.75 exhibited the highest catalytic activity among all the CoO-SnO hybrid oxides. Experimental results showed that the catalysts were considerably stable in the CH combustion reaction, and were verified by X-ray photoelectron spectra (XPS). It was found that CoO was the active species, and SnO acted as a support or a promoting component in the CoO-SnO hybrid oxides. The surface area was not a major factor that affected catalytic activity. The hydrogen temperature-programmed reduction (H-TPR) results demonstrated that the interaction between cobalt and tin oxides accelerated the mobility of oxygen species of CoO-SnO, leading to higher catalytic activity.
