摘要
钙钛矿型氧化物因其成本低、活性高、结构可调等优点,在烟气脱硝领域得到了广泛研究。综述了近年来国内外钙钛矿型氧化物在脱硝领域的研究成果,分析了其在NO分解、还原(NH_(3)-SCR、CO-SCR)和NO氧化等技术中的应用及其反应机理和优缺点,并指出了未来的研究方向是优化钙钛矿结构,提升催化剂的稳定性与抗毒性。
Perovskite oxides have been extensively studied in the field of flue gas denitrification due to their advantages of low cost,high activity and adjustable structure.This paper summarizes the results of national and international research of perovskite-type oxides in the field of denitrification in recent years,and analyzes its application in NO decomposition,NH_(3)-SCR,CO-SCR reduction and NO oxidation technology and its reaction mechanism,advantages and disadvantages.The future research direction is to optimize the structure of perovskite and improve the stability and anti-toxicity of catalysts.
