Metal–organic frameworks (MOFs) are widely researched but applied only in few commercial processes among others due to unknown stability. This study evaluates the stability of four zirconium-based MOFs with different linkers in water at pH 3.0 to 11.0. Results indicate that MOFs with tetratopic linkers (PCN-222, MIP-200) are more stable than those with ditopic or tritopic linkers (UiO-66, MOF-808), with MIP-200 being the most stable despite minor structural changes allowing thermal recrystallization.
