This study showed that the deactivation of modified Fe/Beta SCR catalyst due to HC poisoning was reduced and the NOx efficiency has been improved. The results suggested that by adopting such modification strategy, the potential for Fe/zeolite SCR catalysts for diesel vehicle applications could be increased.
