摘　　要：在节能减排政策的推动下,氮氧化物后处理技术的研究迅速兴起。存储还原(NSR)技术是非常前景的氮氧化物脱除技术。综述了近年来NSR催化剂的研究进展。重点概述了NOx存储-还原技术过程原理和影响因素、NSR催化剂的失活机制及再生、NOx存储-还原性能的检测,最后展望了NSR技术的发展前景。NOx after-treatment technology is arisen at the driving of Energy Saver and Exhaust Reducer policy. The NOx storage and reduction （NSR） technology will be the most promising way to reduce the NOx emission from lean-burn engines, The main advances in different formulated NSR catalysts in the last decade are systematically reviewed in this paper. Special attentions are paid on the NSR reaction process, the NSR catalysts deactivation mechanism and its regeneration,the determination of the storage-reduction properties of the NSR catalyst. At last, the prospect of NSR technology is proposed.
