英文摘要	It is experimentally challenging to generate nano-sized metal oxide clusters with significant intensity as well as to resolve a single hydrogen atom by mass spectrometry (TOF-MS). Herein, the high-resolution tandem time-of-flight mass spectrometer is home-made and the experimental apparatus is capable to perform the reactivity study of nano-sized vanadium oxide clusters. The formation and distribution of nano-sized vanadium oxide cluster anions VxOy- (x up to 70) were analyzed and the photoreaction of alkene attached complex V40O101C2H4- (Or V40O101C3H6-) was studied. Larger VxOy- cluster anions can be generated typically under higher O-2 concentration and the intensity proportion (%) of vanadium oxide cluster with a certain oxygen-deficiency value Delta (Delta= 2y-5x-1 for VxOy-) in each V-x series is nearly invariant. In photoreaction of V40O101C2H4- (orV(40)O(101)C(3)H(6)(-)), the transfer of two oxygen atoms from V40O101- to C2H4 (or C3H6 and the generation of V40O99- dominants the channel. The mass resolution of the primary TOF-MS for V4O101- (similar to 1.5 nm) is up to 13002. The mass resolution of the secondary TOFMS for photoreaction is calculated to be about 4530 to resolve parent (V40O101C2H4-) and daughter ions (V40O99-). (C) 2016 Published by Elsevier B.V.
