Impact of ambient gases on the mechanism of [Cs₈Nb₆O₁₉]-promoted nerve-agent decomposition.

ABSTRACT: The impact of ambient gas molecules (X), NO₂, CO₂ and SO₂ on the structure, stability and decontamination activity of Cs₈Nb₆O₁₉ polyoxometalate was studied computationally and experimentally. It was found that Cs₈Nb₆O₁₉ absorbs these molecules more strongly than it adsorbs water and Sarin (GB) and that these interactions hinder nerve agent decontamination. The impacts of diamagnetic CO₂ and SO₂ molecules on polyoxoniobate Cs₈Nb₆O₁₉ were fundamentally different from that of NO₂ radical. At ambient temperatures, weak coordination of the first NO₂ radical to Cs₈Nb₆O₁₉ conferred partial r
