The Pt/Pd/Rh three-way catalyst was prepared using a high-performance Ce(0.55)Zr(0.35)Y(0.05)La(0.05)O(2) solid solution and high surface area La-stabilized alumina (La/Al(2)O(3)). The activity and durability of the catalyst rapidly ageing in simulated conditions and Under the actual vehicle test conditions were studied. The results revealed that Ce(0.55)Zr(0.35)Y(0.05)La(0.05)O(2) solid solution maintains superior textual and oxygen storage properties, and La/Al(2)O(3) has superior textual properties. The catalyst had high low-temperature activity, wide air-to-fuel ratio windows. and good thermal stability. The results from the emission test of a motorcycle showed that the catalyst can meet Euro III emission requirements.
