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

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
