英文摘要mnox-ceo2 mixed oxides with a mn/(mn + ce) molar ratios of 0-1 were prepared by a modified coprecipitation method and investigated for the complete oxidation of formaldehyde. the mnox-ceo2 with mn/(mn + ce) molar ratio of 0.5 exhibited the highest catalytic activity among the mnox-ceo2 mixed oxides. structure analysis by x-ray powder diffraction and temperature-programmed reduction of hydrogen revealed that the formation of mnox-ceo2 solid solution greatly improved the low-temperature reducibility, resulting in a higher catalytic activity for the oxidation of formaldehyde. promoting effect of pt on the mnox-ceo2 mixed oxide indicated that both the pt precursors and the reduction temperature greatly affected the catalytic performance. pt/mnox-ceo2 catalyst prepared from chlorine-free precursor showed extremely high activity and stability after pretreatment with hydrogen at 473 k. 100% conversion of formaldehyde was achieved at ambient temperature and no deactivation was observed for 120 h time-on-stream. the promoting effect of pt was ascribed to enhance the effective activation of oxygen molecule on the mnox-ceo2 support.
