Investigations of soot combustion on yttria-stabilized zirconia by environmental transmission electron microscopy (ETEM)

- Soot oxidation was carried out over yttria-stabilized zirconia catalyst.
- ETEM in situ observations of soot oxidation were performed with a 1 nm resolution.
- Video sequences show oxidation of soot at the boundary layer with the catalyst.
- Soot/YSZ contact points and their evolution with time are the key parameters.
