英文摘要 | co3o4/ceo2 mixed oxides were prepared by coprecipitation-oxidation, homogeneous precipitation, and complexation-combustion methods. the catalysts were used to catalyze low-temperature co oxidation under dry and humid conditions. the co3o4/ceo2 catalyst prepared by the coprecipitation-oxidation method followed by calcination at 538 k exhibited excellent activity and good resistance to water vapor poisoning. remarkably, a co conversion of 99% was achieved at a temperature as low as 196 k and was maintained more than 400 min under the dry condition. when the reaction was carried out at 298 k, a co conversion of 94% was obtained after running the reaction for 2 400 min. even when 3.1% steam was added, a co conversion of 79% could be kept after 2 400 min time-on-stream at 383 k. it is suggested that the strong interaction between co3o4 and ceo2 is closely related to the preparation route and the calcination temperature and plays a crucial role in the co oxidation over the co3o4/ceo2 catalyst. |
