For experiments in loose contact between soot and catalyst, the
catalytic activity depends on the BET surface area of the catalyst,
and the catalysts Ce0.85−xZr0.15YxO2 (BET = 10–13 m2/g) are more
active than the catalysts Ce1−xYxO2 (BET = 2–3 m2/g). In the loose
contact mode, the yttrium doping and loading have a minor or
null affect on the activity, and the stabilising effect of the BET
area due to zirconium doping prevails.
