Self-assembly of polyoxovanadate-capped polyoxoniobates and their catalytic decontamination of sulfur mustard simulants

Abstract

We report the synthesis and characterization of two discrete vanadoniobates, H₆Cs₄Na₅K₇[V₅Nb₂₃O₈₀]·28H₂O (1) and H₆Cs₄Na₅K₈[V₆Nb₂₃O₈₁]·34H₂O (2), based on a brand new {Nb₂₃} and a 5/6-nuclear polyoxovanadate cap. The two vanadoniobates as heterogeneous catalysts can effectively promote the oxidative decontamination of sulfur mustard simulants.
