摘要
汽车尾气是大气污染的主要来源之一,汽车尾气净化器催化是控制汽车污染的重要手段。因此本文综述了汽车尾气净化催化剂及其载体的研究进展,包括催化剂及其载体的分类及研究进展。并对金属型催化剂及稀土复合型催化剂进行了优缺点的比较,提出了汽车尾气净化催化剂的研究发展方向。
Automobile exhaust is one of the main sources of the air pollution. The catalytic purification by the purifying agents of automobile end - gas is one of the important methods of reducing the automobile pollution. Progress of catalysts for purifying auto emission and its supporters were summarized and developmental direction for purification of auto exhaust was also illustrated. And rare earth metal compound catalyst and a catalyst of the comparative advantages and disadvantages. And automobile exhaust gas purification catalyst of development.
