Figure 3
ETEM images of carbon and 10%Fe/CeO2 recorded at 500 °C in 1 Pa O2; (A,B) – 0 min; (C,D) – 7 min; (B,D) are processed images of (A,C), respectively, by cleaning the background, tracing 10%Fe/CeO2 clusters with a red outline and erasing 10%Fe/CeO2 to increase the contrast. The movement of carbon and 10%Fe/CeO2 is marked by blue and red arrows, respectively. (E) Movement and morphology change of catalysts marked ‘4, 5, and 6’ in (B). (F) Carbon moved towards the fixed catalyst marked ‘1’ in (B).
