摘要
A highly-efficient NH3-SCR catalyst, CeO2/WO3-TiO2, was prepared by a novel stepwise precipitation approach. This catalyst showed excellent catalytic performance, with superior low-temperature activity, high N-2 selectivity and a broad operational temperature window. Furthermore, the CeO2/WO3-TiO2 catalyst could perform well even under an extremely high space velocity condition of 1 000 000 h(-1).
