Title
Impact of synthesis method on catalytic performance of MnOx–SnO2 for controlling formaldehyde emission
Abstract

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.
