NO_x选择性催化还原技术(NH_3-SCR)是当前主流的NO_x控制排放技术。近年来,Ce基催化材料在SCR催化剂的应用受到广泛的关注。目前有大量的文献报道了这方面的研究工作。本文围绕含Ce基催化材料结构、酸碱性、氧化还原能力等因素与SCR脱硝活性之间关系,系统综述Ce基SCR催化剂材料的制备,性能优化、机制和中毒方面的研究,并对其发展趋势进行展望。 NO_x selective catalytic reduction (NH_3-SCR) is the current mainstream NO_x emission control technology. In recent years, Ce-based catalytic materials in the SCR catalyst application has received widespread attention. There are a lot of literature reported in this area of ​​research. In this paper, the relationship between the structure, acid-base, redox ability and SCR denitrification activity of Ce-based catalytic materials was systematically reviewed. The preparation, performance optimization, mechanism and poisoning of Ce-based SCR catalysts were systematically reviewed. Trend outlook.
