Direct Observations of Ceo2-Catalyzed Soot Oxidation at the Nano-Scale Using Environmental Transmission Electron Microscopy 2008-01-0418
Environmental transmission electron microscopy (ETEM) was used to study in situ the kinetics and dynamics of CeO2-catalyzed soot oxidation at the nano-scale. From time-lapsed ETEM image series, direct insight was obtained into structural changes of soot particles in contact with CeO2 during exposure to oxidizing conditions. Based on the insight, it was shown that catalytic soot oxidation was governed by reactions at the CeO2-soot interface and that this finding was consistent with previous findings.
