Abstract
The effect of D2/H2 substitution on the reactions of niobium cluster cations Nb + n (n = 5 − 9) with hydrogen was studied using a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer combined with a laser-ablation/supersonic-jet external ion source. For most cluster sizes, it has been found that the reactions of the Nb + n clusters with H2/D2 mixture yield considerable amounts of Nb n HD+ even at small conversion of Nb + n . These results suggest a mechanism which involves the dissociative chernisorption of H2 on the niobium cluster, followed by the competing stabilization and back dissociation of the energized adduct.
