Platinum, vandium, and water are required for the occurrence of oscillations in diesel exhaust gas upon reduction of NO x with propane on zeolites (see example on the right; X = conversion). Results of experiments with temperature‐programmed reduction suggest that the oscillations originate from redox reactions.
