Rather off the original topic but it seems that using catalysts to 'hold-onto' spare O2 in the exhaust could have many uses in ensuring the cleanest emissions throughout the whole driving cycle.
I found a paper on: Reducibility of Catalyzed Cerium–Praseodymium Mixed Oxides
that claims:
"Quantitative results indicate that [Cerium–praseodymium mixed oxides] may be useful, in conjunction with hydrocarbon traps, for treating automotive cold-start emissions. "
I think they could also be useful in DPF burn off cycle for the same reasons.
