Reaction Dynamics of the Decaniobate Ion [H_xNb_(10)O_(28)]~((6-x)-) in Water

摘要

Key questions in geo- and environmental chemistry concern interactions between water and metal-oxide/mineral surfaces as these are responsible for weathering and for the elimination of pollutants. Large oxide ions could be enormously useful to geochemists in testing hypotheses about reaction pathways at mineral surfaces, but most dissociate rapidly, exchange oxygen atoms too quickly, or have such complicated acid-base chemistry that they are not helpful. Simultaneously, information about reaction pathways in polyoxometalate (POM) ions is needed to understand the degradation of catalysts and the structural evolutions among different POMs.
