Rare earth perovskite-type oxide catalyst as a substitute for traditional raremetal catalyst has a great potential to purify automotive emission due to good catalytic activity and low cost.
The catalyst is modified by a proper amount of the rare-earth metaloxide, so the catalyst has good catalytic performance; and the preparation process has simple operation.
该催化剂经适量稀土金属氧化物改性后,具有较好的催化性能,且制备过程操作简便。
