Self-synthesis and performance analysis of a Cu-Fe composite ZSM-5 zeolitic catalyst for NOx reduction and particulate matter removal using NH3 SCR

Research progress on the preparation of transition metal-modified zeolite catalysts and their catalytic performance for the purification of engine exhausts

“…Therefore, considering the respective advantages of Cu and Fe species, researchers attempted to combine these two elements to overcome the defects of single metal catalysts. 165 Zhang et al 166 synthesized a Cu-SSZ-13 catalyst via a one-pot synthesis using a Cu-TEPA complex as an SDA. Fe-Cu-SSZ-13 catalysts were prepared using ion exchange of Fe into Cu-SSZ-13.…”
