摘要 现阶段,开发低温、高活性、高稳定性、低成本的催化剂是CO-SCR技术的重点研究方向。本文重点介绍了CO-SCR技术的催化还原反应机理,并从贵金属催化剂和过渡金属氧化物催化剂着手,对近年来CO-SCR催化剂的国内外研究进展进行了综述。众多研究表明,CO-SCR催化剂仍存较多局限性,若要实现大规模工业应用,需进一步结合理论计算,提高催化剂抗氧化性能,分析H2O、SO2和碱金属等因素在CO-SCR反应中的详细影响路径等。

Abstract:  At present, developing low temperature, high activity, high stability and low cost catalysts is the key research direction of CO-SCR technology. This paper mainly introduces the catalytic reduction mechanism of CO-SCR technology, and reviews the research progress of CO-SCR catalysts at home and abroad in recent years, starting with noble metal catalysts and transition metal oxides catalysts. Numerous studies have shown that CO-SCR catalysts still have many limitations. To achieve large-scale industrial applications, further theoretical calculations need to be combined to improve the antioxidant performance of the catalyst, and the detailed influence paths of factors such as H2O, SO2, and alkali metals in CO-SCR reactions need to be analyzed.
Key words:  selective catalytic reduction technology    catalyst    reaction mechanism    theoretical calculation    industrial application
