Abstract We present an iron‐containing metal–organic framework, MIL‐100(Fe), for ozone removal. MIL‐100(Fe) exhibits long‐lasting ozone conversion efficiency of 100 % for over 100 h under a relative humidity of 45 % and space velocity of 1.9×10 5 h −1 at room temperature, which is well beyond the performance of most porous or metal catalysts such as activated carbon and α‐MnO 2 . We also investigated the impact of humidity level and elucidated the plausible reaction mechanism, which is further confirmed by DFT calculations. Furthermore, MIL‐100(Fe) can be processed into films and used as filtration layer in a mask to protect personnel against ozone contamination. This study demonstrates the promising potential of MOFs in ozone pollution control, and also offers new insights for the design of ozone decomposition catalysts.
