摘    要:The reactions of cationic zirconium oxide clusters (ZrxOy^+) with ethylene (C2H4) were investigated by using a time-of-flight mass spectrometer coupled with a laser ablation/supersonic expansion cluster source. Some hydrogen containing products (ZrO2)xH^+(x=-1-4) were observed after the reaction. The density functional theory calculations indicate that apart from the common oxygen transfer reaction channel, the hydrogen abstraction channel can also occur in (ZrO2)x^++C2H4, which supports that the observed (ZrO2)xH^+ may be due to (ZrO2)x^++C2H4→(ZrO2)xH^++C2H3. The rate constants of different reaction channels were also calculated by Rice-Rarnsberger-Kassel-Marcus theory.

Abstract:The reactions of cationic zirconium oxide clusters ZrxOy+ with ethylene (C2H4) were inves-tigated by using a time-of-flight mass spectrometer coupled with a laser ablation/supersonic expansion cluster source. Some hydrogen containing products (ZrO2)xH+ (x=1~4) were observed after the reaction. The density functional theory calculations indicate that apart from the common oxygen transfer reaction channel, the hydrogen abstraction channel can also occur in (ZrO2)x++C2H4, which supports that the observed (ZrO2)xH+ may be due to (ZrO2)x++C2H4→(ZrO2)xH++C2H3. The rate constants of different reaction channels were also calculated by Rice-Ramsberger-Kassel-Marcus theory.
