CO and soot oxidation over macroporous perovskite LaFeO 3

•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.
