摘要：

V-51 NMR spectroscopy has been used to characterize the complexes formed between hydrogen peroxide and vanadate under near-neutral conditions in aqueous solution. The formation constants of the mono-, di-, and triperoxovanadates and tetraperoxodivanadate have been measured and the proton requirements for product formation determined. Under the conditions of these studies, the peroxide was found to undergo slow catalytic decomposition. Studies of the decomposition reaction suggested that the monoperoxovanadate is involved in a disproportionation of the hydrogen peroxide, which occurs by a combination of photo-and thermochemical mechanisms. The decomposition reaction is strongly inhibited by the presence of peptides.
