1. Impregnation method was established
Thin layer of metal oxides can be formed on ZSM-5 surface by incipient impregnation method
No other structure observed from the metal oxide coated ZSM-5 (SEM, XRD)
Catalytic activity was not sufficient
(except SnO-Al2O3)
- catalytic activity reason (Calc. Temp, metals)
- low reaction temperature reason
Search better metal oxides for the reaction
CeO2, NiO, VO, CaO, etc

12. Used SnO-(Al2O3)2/nano(M)-ZSM-5
Future works
Synthesize Sn-ZSM-5 crystal
(impurity level of SnO)
Loading SnO only on ZSM-5
Loading SnO-Al2O3 at pH 7.0 with higher T
& longer aging time
