英文摘要	Cerium-vanadium oxide cluster cations CeVO5 (+) were generated by laser ablation, mass-selected using a quadrupole mass filter, thermalized through collisions with helium atoms, and then reacted with ethene molecules in a linear ion trap reactor. The cluster reactions have been characterized by time-of-flight mass spectrometry and density functional theory calculations. The CeVO5 (+) cluster has a closed-shell electronic structure and contains a peroxide (O-2(2-)) unit. The cluster bonded O-2(2-) species reactive enough to oxidize a C2H4 molecule to generate C2H4O2 that can be an acetic acid molecule. Atomic oxygen radicals (O-center dot), superoxide radicals (O-2(-center dot)), and peroxides are the three common reactive oxygen species. The reactivity of cluster bonded O-center dot and O-2(-center dot) radicals has been studied while the O-2(2-) spies were generally thought to be much less reactive or inert toward small molecules under thermal collision conditions. This work is among the first to report the reactivity of the peroxide unit on transition metal oxide clusters with hydrocarbon molecules, to the best of our knowledge.
