摘要
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。
Nitrogen oxides（NOx） selective catalytic reduction（SCR） was used as the major technique for NOx elimination. In the past decades,Ce based materials have been paid widely attention and investigated. In this paper,the studies on preparations,performance,mechanism and poisoning of Ce contained catalysts and the relationships between the structure,acidity and redox property over the catalysts were comprehensive reviewed. The potential development on the applications of SCR catalysts was also discussed.
