Characteristics analysis of hybrid ZSM-5 zeolite catalyst with nano La2Zr2O7 for ammonia-selective catalytic reduction (NH3-SCR) of NOx

Abstract

The characteristical effects of ZSM-5 by doping La2Zr2O7 nanoparticle was investigated based on the application of ammonia-selective catalytic reduction (NH3-SCR). The hybrid ZSM-5 zeolite catalyst was synthesized by the Ion exchange and wet impregnation method to develop Cu-ZSM-5 and 5%, 10%, & 15% of La2Zr2O7 based Cu-ZSM-5. The characterization of hybrid catalyst was analysed by XRD, SEM, XPS, BET, FT-IR, & UVVis. From the analysis of the characteristics, La2Zr2O7 doped Cu-ZSM-5 hybrid zeolite catalyst exhibits excellent properties towards the application of ammonia-selective catalytic reduction (NH3-SCR) for the reduction of oxides of nitrogen to achieve EURO VI norms
