Stability improvement of Cu3(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 Cu(2)OH(BTC)(H(2)O)(n)·2nH(2)O from 343 K onwards.
