The reactivity of metal oxide clusters toward hydrocarbon molecules can be changed, tuned, or controlled by doping. Cerium‐doped vanadium cluster cations CeV 2 O 7 + are generated by laser ablation, mass‐selected by a quadrupole mass filter, and then reacted with C 2 H 4 in a linear ion trap reactor. The reaction is characterized by a reflectron time‐of‐flight mass spectrometer. Three types of reaction channels are observed: 1) single oxygen‐atom transfer , 2) double oxygen‐atom transfer , and 3) CC bond cleavage. This study provides the first bimetallic oxide cluster ion, CeV 2 O 7 + , which gives rise to CC bond cleavage of ethene. Neither Ce x O y ± nor V x O y ± alone possess the necessary topological and electronic properties to bring about such a reaction.
