Influence of Different Preparation Methods of Copper Loading on Na-Y Zeolite for Green Gas Emission

Abstract—This research was focused on different preparation methods of copper loading on zeolite. Cu cation supported on Na-Y zeolite (Cu-Y) was prepared by aqueous solution ion exchange and incipient wetness impregnation methods. Different amounts of copper (II) were loaded in the Na-Y zeolite. The catalysis materials were characterized by X-ray diffraction, X-ray fluorescence and Brunauer-Emmett-Teller. The results show that Cu loading did not change the structure of Na-Y zeolite. The obtained Cu/Y has enlarged pore size and octahedral shaped crystal with approximately 0.19 ± 0.08 μm diameter. 5.5 wt. % Cu/Y with impregnation method clearly exhibits a higher BET surface area and a total pore volume than 5.5 wt. % solution ion exchanged.

Index Terms—Na-Y zeolite, green gas emission, X-ray powder diffraction, scanning electron microscope (SEM).
