摘要
制备了以贱金属氧化物,稀土及少量贵金属Pd为活性组分,以蜂窝陶瓷为载体的机动车尾气净化催化剂。研究了其制备工艺及活性组分的负载量对机动车尾气净化效果的影响。
Three types of catalyst used for autombile emissions control that were multi-metal oxide catalyst, rare earth met-al oxide catalyst, noble-rare earth metal oxide catalyst had been prepared and compared. It has been found that their catalytic performances were mainly depended on preparation factors.
