采用一种新型的、耐高温和具有大比表面积的氧化铝为载体,制备了Pt-Rh密偶催化剂,并用其催化控制汽车冷启动期间的尾气排放. 实验结果表明,该催化剂对汽车尾气(特别是尾气中的烷烃)具有较高的催化活性,同时催化剂还具有很好的抗高温老化性能,完全能够满足高性能密偶催化剂的要求.
A noble Pt-Rh close coupled catalyst supported on a novel high surface area alumina was prepared to control the exhaust gas emission of automobiles. The results indicated that the prepared catalyst has good activity at low temperature and good stability at high temperature, which can satisfy the requirements of a high performance close coupled catalyst.
