  • N2O can initiate diesel-soot oxidation but requires the presence of a catalyst.

  • Non-selective ammonia-SCR can be used as an in-situ source of N2O.

  • Supported Ag can catalyse both non-selective SCR and the soot + N2O reaction.

  • Soot control achieved in diesel exhaust by NH3 addition to Ag-catalysed filter.
