Abstract: Vanadiumoxide cluster anions Vm16On–and Vm18On–were prepared by laser ablation and reacted withhydrogen sulfide (H2S) in a fast flow reactor under thermalcollision conditions. A time-of-flight mass spectrometer was usedto detect the cluster distributions before and after the interactionswith H2S. The experiments suggest that the oxygen-for-sulfur(O/S) exchange reaction to release water was evidenced in the reactorfor most of the cluster anions: VmOn– H2S →VmOn–1S– H2O. For reactions of clustersVO3–and VO4–with H2S, consecutive O/S exchange reactions led to thegeneration of sulfur containing vanadium oxide cluster anions VO3–kSk–(k= 1–3) and VO4–kSk–(k= 1–4). Density functional theory calculationswere performed for the reactions of VO3–4–with H2S, and the results indicate that the O/S exchangereactions are both thermodynamically and kinetically favorable, whichsupports the experimental observations. The reactions of VmOn牛겵cations with H2S have been reported previously (Jia, M.-Y.; Xu, B.; Ding, X.-L.; Zhao, Y.-X.; He, S.-G.; Ge, M.-F.J. Phys. Chem. C2012, 116, 9043), and this study of cluster anionsprovides further new insights into the transformations of H2S over vanadium oxides at the molecular level. [ABSTRACT FROM AUTHOR]
