ETEM of carbon and 10%Fe/CeO2 during the reaction at 500 °C in 1 Pa air (~0.2 Pa O2); (A) 0 min; (B) 7 min. The 10%Fe/CeO2 catalyst clusters are circled in red lines. The movement of carbon and 10%Fe/CeO2 is marked by blue and red arrows, respectively. (C) Correlation of contact length and reaction rate ‘r’.
