- •
Catalytic performances of bulk, supported and porous LaFeO3 for CO and soot oxidation are investigated.
- •
Porous LaFeO3 has enhanced surface area, richer active lattice oxygen and stronger reducibility relative to the other two samples.
- •
Porous LaFeO3 shows the best activity to both CO and soot oxidation.
- •
Porous LaFeO3 shows strong resistance to vapor and its activity can be recovered when vapor is switched off.
- •
Porous LaFeO3 is highly stable and the structure remains unchanged after the reaction.
