摘　　要：NO_x排放对人体和环境造成较大危害。SCR脱硝技术已成为减少NO_x排放的主流技术,在SCR脱硝技术中催化剂占有重要作用,开发出具有高活性、高稳定性和高寿命的催化剂至关重要。阐述了金属氧化物载体、分子筛载体以及碳载体催化剂的选择性催化还原法脱除NO_x的研究进展,对SCR脱硝催化剂研究领域存在的问题进行探讨,并展望了今后研究方向。The emission of nitrogen oxides is harmful to human body and environment. At present, the se- lective catalytic reduction denitration technology has become a mainstream technology to reduce NOx emission. Catalyst in selective catalytic reduction denitration technology plays an important role. There- fore, the development of the catalyst with high active and stability, and long life is essential. The research status in the catalysts for selecti~,e catalytic： reduction of NOx, including metal oxide supports, zeolite sup- ports and carbon supports was described. Furthermore, some problems existing in the field of the SCR cat- alysts were discussed. The research prospects in future were outlined.
