摘　　要：研究了氯离子对Pd/La-Ce-Al汽车尾气净化催化剂氧化性能的影响。结果表明:氯离子在Pd/La-Ce-Al催化剂中的存在降低了催化剂对CO和C3H8的氧化活性。The oxidative performance of Pd/La-Ce-Al automobile exhaust catalyst caused by chloride concentration was studied. It was found that oxidative activities of CO and C3Hs were reduced when chloride ion was added to Pd/La-Ce-Al catalyst.
