摘要

•Hierarchical ordered MnFe1-δCoδOx ternary oxide catalysts were prepared.•Co doping can enhance the low-temperature performance of the NH3-SCR reaction.•The enhanced performance depends on the increased acidity and redox of Hierc-MnFe1-δCoδOx.•Co doping can retard the sulfuration rates of Hierc-MnFe1-δCoδOx catalysts.
