摘　　要：柴油烟气中的污染物对环境造成重大污染,给人类健康造成重大威胁。为了缓解这一现象,广大研究者对柴油烟气排后处理技术开展了针对性研究。结果表明:钙钛矿型四效催化技术是控制排放效果最好和前景最好的排后处理技术之一,不同的钙钛矿型催化活性组分和催化剂载体对四效催化剂的净化效果有着显著的影响。最后探讨了钙钛矿型四效催化技术存在的问题和未来的发展趋势。Pollutants from diesel smoke cause heavy pollution to the environment and pose a great threat to human health. In order to alleviate this phenomenon,most studies are carried out on treatment technology of diesel flue gas after exhausting.Research shows that perovskite type four way catalytic technology for controlling the emissions is one of the best technology. The effects of different perovskite type catalytic component and catalyst carrier on four way catalytic purification effect are significant.The paper discussed the existence problems of perovskite type four way catalytic technology and the future development trend.
