Abstract
An emission control catalyst for treating an engine exhaust includes non-precious metal group (“NPGM”) mixed phase oxide catalyst having a mullite phase containing optionally in close contact with other metal oxides. The mixed phase catalyst may be included in one or more layers or zones of a multi-layered or multi-zoned emission control catalyst and optionally in combination with precious metal catalysts such as Pt, Pd and Au.
