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

摘要

We report the synthesis and characterization of two discrete vanadoniobates, H6Cs4Na5K7V5Nb23O80center dot 28H(2)O (1) and H6Cs4Na5K8V6Nb23O81center dot 34H(2)O (2), based on a brand new {Nb-23} and a 5/6-nuclear polyoxovanadate cap. The two vanadoniobates as heterogeneous catalysts can effectively promote the oxidative decontamination of sulfur mustard simulants.
