An unprecedented Zr-added poly(POM), [H 2N(CH 3) 2] 10H 14[(Zr 2P 2W 16O 61) 3]·7H 2O, has been made under hydrothermal conditions, and as a heterogeneous catalyst, its selective oxidative degradation of a sulfur mustard simulant CEES has further been studied.
A novel Zr-added trimer, [H 2N(CH 3) 2] 10H 14[(Zr 2P 2W 16O 61) 3]·7H 2O (1), has been made under hydrothermal conditions, and contains the highest number of Zr centers in known Dawson-type poly(POM)s. A remarkable feature of this study is the first discovery of a new type of divacant [α-5,10-P 2W 16O 60] 14− fragment, which assembles with Zr 4+ ions to form a cyclic trimer. Furthermore, 1 as a heterogeneous catalyst exhibits high activity for the selective oxidative degradation of a sulfur mustard simulant CEES.
