摘要
The three-way catalytic behaviour (CO, HC and NO, conversions and light-off temperatures) of MN/CeO2/Al9O3 (MN: Pt, Ph, Pt-Ph) catalysts, fresh and aged under severe oxidizing, reducing and cycled environments, has been analyzed. The bimetallic Pt-Pi catalyst resulted the most active among those tested.
