Abstract:

We summarize the recent progress in the preparation of 8MR zeolites(CHA, AEI, RTH) for the selective catalytic reduction of NOx(NH3-SCR) in diesel, discuss the performance differences of 8MR zeolites synthesized by different routes in SCR. Finally, the challenges in the preparation of 8MR zeolites are also discussed.

Key words: 8MR zeolites, Cu-Tetraethylenepentamine(Cu-TEPA), Organotemplate-free method, Solvent-free method, NH3-Selective catalytic reduction(SCR)
