In this work, the hydrothermal and chemical stability towards acids, bases, air, water, and peroxides of Metal Organic Frameworks, that are commonly considered to be stable, is presented. As a proof of stability both the crystallinity and porosity are measured before and after exposure to the stress test. The major part of the MOFs examined in this study show a good hydrothermal stability except for UiO-67, NH 2 -MIL-101 (Al) and CuBTC. The chemical stabilities towards acids and bases show a similar tendency and an ordering can be proposed as: MIL-101(Cr) > NH 2 -UiO-66 > UiO-66 > UiO-67 > NH 2 -MIL-53 > MIL-53(Al)>ZIF-8 > CuBTC > NH 2 -MIL-101(Al). In the tests with H 2 O 2 most materials behaved poorly, only the UiO-66 and NH 2 -UiO-66 frameworks show a good stability.
