چکیده انگلیسی
The impact of synthesis method on catalytic performances of MnOx–SnO2 was studied for controlling formaldehyde emission during cold start and warm-up periods of methanol-gasoline/diesel fuel vehicles. MnOx–SnO2 synthesized by a redox co-precipitation method exhibited much higher activity towards complete oxidation of formaldehyde than that by a conventional co-precipitation one. The results of XPS, XRD and H2-TPR characterizations revealed that higher oxidation state of manganese, the formation of solid solution between MnOx and SnO2, and more facile redox capability were responsible for higher activity.
