Stability improvement of Cu-3(BTC)(2) metal-organic frameworks under steaming conditions by encapsulation of a Keggin polyoxometalate

Cu-3(BTC)(2) with an incorporated Keggin polyoxometalate was demonstrated to be stable under steaming conditions up to 483 K, while the isostructural HKUST-1 degrades and transforms into [Cu2OH(BTC)(H2O)](n)center dot 2nH(2)O from 343 K onwards.
