(A) The structure of the PCN-222(Cr)/MOF-545(Zr): (a) the SEM image of the MOF, (b) 3D structure of the MOF, (c) view of the Zr 6 node, (d) Zn-OH-Zn active site in phosphotriesterase, and (e) the concept of generating singlet oxygen by porphyrin moieties in MOF under irradiation. (B) MOF-catalyzed dual-reaction to transform toxic chemical warfare agent simulants CEES and DMNP to nontoxic oxidative and hydrolytic products: (a) the setup for the experiment, and (b) kinetic profiles for hydrolysis of DMNP and oxidation of CEES with the MOF.
