Abstract

The reactions of adsorbed oxygen species, $O_2^-$ and $O^-$, with propylene on ZnO were studied by EPR spectroscopy and temperature programmed desorption technique. Propylene interacts with adsorbed $O_2^-$ at $25^{\circ}C$ and the surface intermediate was decomposed to CO, $H_2$, $CO_2$ and $CH_4$ by raising the temperature above $200^{\circ}C$, while $O^-$ gave the products of complete oxidation, $CO_2$ and $H_2O$ above $300^{\circ}C$.

산화아연에서 흡착산소종과 프로필렌의 상호작용을 EPR과 TPD를 사용 연구했다. 흡착산소종 $O_2^-$$25^{\circ}C$에서 프로필렌과 작용, g=1.96의 반응중간체를 생성했는데 이는 $200^{\circ}C$이상에서 $H_2$, CO와 $CO_2$, $CH_4$등으로 분해되었다. 흡착산소종 $O^-$는 프로필렌과 상호작용, g=2.008의 중간체 및 완전산화물인 $CO_2$, $H_2O$ 등을 생성했다.
